Design Guidelines for Frosted Detail Plastic

The rules to follow in order to create successful products in Frosted Detail Plastic.


284 × 184 × 203 mm

 Max bounding box

For us to be able to make a product, each of its pieces must fit within these dimensions.

For Frosted Detail Plastics, the maximum bounding box is determined by the size of the printer we use to create your product.

To ensure the successful creation of your product, make sure the bounding box fits within our maximum limit. If it does not, you can try scaling it down, removing unnecessary features to reduce the bounding box, or considering another material with a bigger maximum bounding box.


X + Y + Z ≥ 12 mm
At least two axes must be ≥ 2.49 mm

Min bounding box

For us to be able to make a product, each of its pieces must be bigger than these dimensions.

For Frosted Detail Plastics, the minimum bounding box is determined by the printer’s ability to successfully print very tiny products.

To ensure the successful creation of your product, make sure the bounding box of your product is larger than our minimum. If it is not, you can try scaling it up, thickening, combining, or enlarging parts and features, or trying a material with a smaller minimum bounding box.


0.3 mm thick

Min supported wall thickness

A supported wall is one connected to other walls on two or more sides.

For Frosted Detail Plastics, the minimum supported wall is determined by our ability to successfully clean your product once it has been removed from the printer. Walls that are too thin will collapse when the wax-like support material is melted away in an oven.

To ensure the successful creation of your product, make sure supported walls are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a thinner minimum supported wall requirement.

Min unsupported wall thickness

0.6 mm thick

An unsupported wall is one connected to other walls on less than two sides.

For Frosted Detail Plastics, the minimum unsupported wall is determined by our ability to successfully clean your product once it has been removed from the printer. Walls that are too thin will collapse when the wax-like support material is melted away in an oven.

To ensure the successful creation of your product, make sure unsupported walls are thicker than the minimum requirement. If they are not, try making them thicker, adding supports, or considering a material with a thinner minimum unsupported wall requirement.

Min supported wires

0.6 mm thick

A wire is a feature whose length is greater than two times its width. A supported wire is connected to walls on both sides.

For Frosted Detail Plastics, the minimum supported wire is determined by our ability to successfully clean your product once it has been removed from the printer. Wires that are too thin will collapse when the wax-like support material is melted away in an oven.

To ensure the successful creation of your product, make sure supported wires are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a thinner minimum supported wire requirement.

Min unsupported wires

0.8 mm thick
1.0 mm if bearing weight (like a sprue)

A wire is a feature whose length is greater than two times its width. An unsupported wire is connected to walls on less than two sides.

For Frosted Detail Plastics, the minimum unsupported wire is determined by our ability to successfully clean your product once it has been removed from the printer. Wires that are too thin will collapse when the wax-like support material is melted away in an oven.

To ensure the successful creation of your product, make sure unsupported walls are thicker than the minimum requirement. If they are not, try making them thicker, adding supports, or considering a material with a thinner minimum unsupported wall requirement.

0.1 mm high & wide
Min embossed detail

A detail is a feature whose length is less than twice its width. Embossed details stick out from a surface.

For Frosted Detail Plastics, the minimum detail is determined by the printer’s resolution. When detail dimensions are below the minimum, the printer may not be able to accurately replicate them.

To ensure details come out clearly, make them larger than the indicated minimum. We may refrain from printing products with details smaller than the minimum since the physical product will not be true to your design. If your product has details smaller than the minimum, try making them larger or removing them.


0.1 mm high & wide

Min engraved detail

A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.

For Frosted Detail Plastics, the minimum detail is determined by the printer’s resolution. When detail dimensions are below the minimum, the printer may not be able to accurately replicate them.

To ensure details come out clearly, make them larger than the indicated minimum. We may refrain from printing products with details smaller than the minimum, since the final product will not be true to your design. If your product has details smaller than the minimum, try making them larger, or removing them.

Min escape holes

4.0 mm diameter for one escape hole
2.0 mm diameter when there are two or more escape holes

Escape holes allow unbuilt material inside hollow products to be removed.

When printing in Frosted Detail Plastics, hollow parts of your product are filled in with a waxy support material, which is melted out in an oven before we ship your product. If escape holes are not large enough, this wax will remain inside the product.

To ensure the successful creation of your product, make sure the escape holes are large enough and positioned in a way so the wax support material can successfully drain out as it melts. Insufficiently large escape holes will trap wax inside your model, making it frostier and denser than intended. This trapped wax can also cover up details on internal geometries. For most products, we recommend two holes of 2mm in diameter each. Having your holes at the opposite ends of the product (one on top, one on bottom) will also help the wax to drain more easily.

A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.


0.05 mm clearance

 Clearance

Clearance is the space between any two walls, wires, or separate parts.

Frosted Detail Plastics are printed in acrylic plastic cured by a UV light. When the clearance between parts or features is too small, partially cured acrylic can fuse together the separate bodies.

To ensure the successful creation of your product, make the clearance between parts, walls, and wires is greater than the indicated minimum. If your clearance is too small, try making the gap bigger, or consider fusing the parts or features if their independence is unnecessary.

Design Guidelines for Full Color Sandstone

The rules to follow in order to create successful products in Full Color Sandstone

Max bounding box

250 × 380 × 200 mm

For us to be able to make a product, each of its pieces must fit within these dimensions.

For Full Color Sandstone, the maximum bounding box is determined by the size of the printer we use to create your product.

To ensure the successful creation of your product, make sure the bounding box fits within our maximum limit. If it does not, you can try scaling it down, removing unnecessary features to reduce the bounding box, or considering another material with a bigger maximum bounding box.

Min bounding box

X + Y + Z ≥ 10 mm

For us to be able to make a product, each of its pieces must be bigger than these dimensions.

For Full Color Sandstone, the minimum bounding box is determined by the printer’s ability to successfully print very tiny products.

Min supported wall thickness

2.0 mm

A supported wall is one connected to other walls on two or more sides.

For Full Color Sandstone, the minimum supported wall is determined by our ability to successfully remove your product from the powder bed in the printer and clean it. Walls that are too thin will break in this process.

To ensure the successful creation of your product, make sure the supported walls in your product are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a thinner minimum supported wall requirement.

Min unsupported wall thickness

3.0 mm

An unsupported wall is one connected to other walls on less than two sides.

For Full Color Sandstone, the minimum unsupported wall is determined by our ability to successfully remove your product from the powder bed in the printer and clean it. Walls that are too thin will break in this process.

To ensure the successful creation of your product, make sure the unsupported walls in your product are thicker than the minimum requirement. If they are not, try making them thicker, adding supports, or considering a material with a thinner minimum unsupported wall requirement.

Min supported wires

2.0 mm

A wire is a feature whose length is greater than two times its width. A supported wire is connected to walls on both sides.

For Full Color Sandstone, the minimum supported wire is determined by our ability to successfully remove your product from the powder bed in the printer and clean it. Wires that are too thin will break in this process.

Min embossed detail

0.4 mm high & wide

A detail is a feature whose length is less than twice its width. Embossed details stick out from a surface.

For Full Color Sandstone, the minimum detail is determined by the printer’s resolution. When detail dimensions are below the minimum, the printer may not be able to accurately replicate them.

To ensure details come out clearly, make them larger than the indicated minimum. We may refrain from printing products with details smaller than the minimum, since the final product will not be true to your design. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.

Min engraved detail

0.4 mm high & wide

A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.

For Full Color Sandstone, the minimum detail is determined by the printer’s resolution. When detail dimensions are below the minimum, the printer may not be able to accurately replicate them.

To ensure details come out clearly, make them larger than the indicated minimum. We may refrain from printing products with details smaller than the minimum, since the physical product will not be true to your design. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.

Min escape holes

25 mm diameter for one escape hole

15 mm diameter when there are two or more escape holes

10 mm diameter when there are four or more escape holes

Escape holes allow unbuilt material inside hollow products to be removed.

When Full Color Sandstone products contain hollow cavities, they are often still filled with powder even after they are removed from the build tray. Small escape holes and difficult geometry can make it impossible to remove excess powder.

When products contain hollow cavities, they are often filled with powder even after they are removed from the build tray. If escape holes are not large enough, or the geometry of the product makes it difficult to shake or blast the powder out, we cannot successfully clean it. To ensure a successful, cleanable product, make sure to include sufficiently large escape holes for each hollow cavity in your product. Multiple escape holes are recommended for large hollow parts. A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape; so, multiple escape holes at both ends of the cavity are recommended. If your escape holes are insufficient, try enlarging them, adding more, or filling in the hollow space.

A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.

Clearance

0.9 mm clearance

Clearance is the space between any two parts, walls or wires.

Full Color Sandstone products are printed by depositing a binder material onto a bed of gypsum powder, layer by layer. If features are too close together, it can be difficult to clean out excess powder.

To ensure the successful creation of your product, make the clearance between features is greater than the indicated minimum. If your clearance is too small, try making the gap bigger, or consider fusing the parts or features if their independence is unnecessary. You can also try a material with a smaller minimum clearance.

Design Guidelines for Gold

The rules to follow in order to create successful products in Gold.

Max bounding box

89 × 89 × 100 mm

For us to be able to make a product, each of its pieces must fit within these dimensions.

For Gold, the maximum bounding box is determined by the size of the printer we use to create a wax version of your product, as well as the limitations of the plaster molds used for casting.

To ensure the successful creation of your product, make sure the bounding box fits within our maximum limit. If it does not, you can try scaling it down, removing unnecessary features to reduce the bounding box, or consider another material with a bigger maximum bounding box.

Min bounding box

2.4 × 2.4 × 0.6 mm

For us to be able to make a product, each of its pieces must be bigger than these dimensions.

For Gold, the minimum bounding box is determined by our ability to successfully cast very tiny products.

To ensure the successful creation of your product, make sure the bounding box of your product is larger than the minimum. If it is not, you can try scaling it up, thickening, combining, or enlarging parts and features, or trying a material with a smaller minimum bounding box.


0.8 mm thick

 Min supported wall thickness

A supported wall is one connected to other walls on two or more sides.

For Gold, the minimum supported wall is determined by our ability to successfully print your product in wax and then cast it in a plaster mold. Walls that are too thin will break in the mold-making process.

To ensure the successful creation of your product, make sure supported walls are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a thinner minimum supported wall requirement.

An unsupported wall is one connected to other walls on less than two sides.

For Gold, the minimum unsupported wall is determined by our ability to successfully print your product in wax and then cast it in a plaster mold. Walls that are too thin will break in the mold-making process.

To ensure the successful creation of your product, make sure unsupported walls are thicker than the minimum requirement. If they are not, try making them thicker, adding supports, or considering a material with a thinner minimum unsupported wall requirement.

Min supported wires

0.8 mm thick

A wire is a feature whose length is greater than two times its width. A supported wire is connected to walls on both sides.

For Gold, the minimum supported wire is determined by our ability to successfully print your product in wax, create a plaster mold, and then cast and polish the metal object. Wires need to be strong enough to not break during the wax printing and plaster casting process, and to allow metal to flow within the part during metal casting.

To ensure the successful creation of your product, make sure supported wires are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a smaller minimum supported wire requirement. If you have bulky areas of a model connected by thin wires, these wires will need to be significantly thicker than the minimum to allow the metal to successfully flow within the model.

Min unsupported wires

1.0 mm thick

A wire is a feature whose length is greater than two times its width. An unsupported wire is connected to walls on less than two sides.

For Gold, the minimum unsupported wire is determined by our ability to successfully print your product in wax, create a plaster mold, and then cast and polish the metal object. Wires need to be strong enough to not break during the wax printing and plaster casting process, and to allow metal to flow within the part during metal casting.

To ensure the successful creation of your product, make sure unsupported wires are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a smaller minimum unsupported wire requirement. If you have bulky areas of a model connected by thin wires, these wires will need to be significantly thicker than the minimum to allow the metal to successfully flow within the model.


0.40 mm high & wide

Min embossed detail

A detail is a feature whose length is less than twice its width. Embossed details stick out from a surface.

For Gold, the minimum detail is determined by the wax printer’s resolution. When detail dimensions are below the minimum, the printer may not be able to accurately replicate them. Details smaller than the minimum may also be lost or warped in the polishing process.

To ensure details come out clearly, make them larger than the indicated minimum. We may be unable to print products with details smaller than the minimum, since the final product will not be true to your design. If your design has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.


0.35 mm high & wide

Min engraved detail

A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.

For Gold, the minimum detail is determined by the casting process. Gold products are printed in wax, and then a liquid plaster is poured around them and solidifies into a mold. When liquid metal is poured into this mold, the pieces of plaster that create engraved details can break off if they are too small.

To ensure details come out clearly, make them larger than the indicated minimum. We may be unable to print products with details smaller than the minimum, since the final product will not be true to your design. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material that can print in finer detail.

Min escape holes

4.0 mm diameter for one escape hole

2.0 mm diameter when there are two or more escape holes

Escape holes allow unbuilt material inside hollow products to be removed.

To create Gold products, a plaster mold is poured around a wax print of your product, and then Gold is cast into the plaster mold. For products with hollow areas, escape holes are essential for two parts of this process. First, the liquid plaster must be able to enter the hole to fill in the hollow area. Then, once the metal is cast, the escape hole must be large enough to allow removal of the hardened plaster from the hollow area. If escape holes are too small, the hollow area may be completely filled in with metal or plaster.

To ensure the successful creation of your product, make sure the escape holes are large enough to allow the plaster to get in and out. Multiple holes make this process easier. If your holes are not big enough, you can enlarge them, add more, or fill in the hollow areas so they are solid. Positioning escape holes at the opposite ends of a product (one on top, one on the bottom) will help the finishing process.

A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.

Clearance

0.3 mm clearance

Clearance is the space between any two parts, walls or wires.

Gold products are printed in wax, and then a liquid plaster mold is poured around them. If the clearance between features is very small, the plaster may not fully infiltrate tiny gaps. Even if it does fully infiltrate the gaps, a plaster wall that is too thin can break when the liquid metal is poured around it. Both issues can cause defects in your product.

To ensure the successful creation of your product, make the clearance between walls and wires greater than the indicated minimum. If your clearance is too small, try making the gap bigger, or consider fusing the features if their independence is unnecessary. You can also try a material with a smaller minimum clearance.

If your clearance is too small, try making the gap bigger, or consider fusing the features if their independence is unnecessary. You can also try a material with a smaller minimum clearance.

Design Guidelines for Silver

The rules to follow in order to create successful products in Silver.

Max bounding box

89 × 89 × 100 mm

For us to be able to make a product, each of its pieces must fit within these dimensions.

For Silver, the maximum bounding box is determined by the size of the printer we use to create a wax version of your product, as well as the limitations of the plaster molds used for casting.

To ensure the successful creation of your product, make sure the bounding box fits within our maximum limit. If it does not, you can try scaling it down, removing unnecessary features to reduce the bounding box, or consider another material with a bigger maximum bounding box.

Min bounding box

2.4 × 2.4 × 0.6 mm

For us to be able to make a product, each of its pieces must be bigger than these dimensions.

For Silver, the minimum bounding box is determined by our ability to successfully cast very tiny products.

To ensure the successful creation of your product, make sure the bounding box of your product is larger than the minimum. If it is not, you can try scaling it up, thickening, combining, or enlarging parts and features, or trying a material with a smaller minimum bounding box.


0.8 mm thick

 Min supported wall thickness

A supported wall is one connected to other walls on two or more sides.

For Silver, the minimum supported wall is determined by our ability to successfully print your product in wax and then cast it in a plaster mold. Walls that are too thin will break in the mold-making process.

To ensure the successful creation of your product, make sure supported walls are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a thinner minimum supported wall requirement.


0.8 mm thick

Min unsupported wall thickness

An unsupported wall is one connected to other walls on less than two sides.

For Silver, the minimum unsupported wall is determined by our ability to successfully print your product in wax and then cast it in a plaster mold. Walls that are too thin will break in the mold-making process.

To ensure the successful creation of your product, make sure unsupported walls are thicker than the minimum requirement. If they are not, try making them thicker, adding supports, or considering a material with a thinner minimum unsupported wall requirement.

Min supported wires

0.8 mm thick

A wire is a feature whose length is greater than two times its width. A supported wire is connected to walls on both sides.

For Silver, the minimum supported wire is determined by our ability to successfully print your product in wax, create a plaster mold, and then cast and polish the metal object. Wires need to be strong enough to not break during the wax printing and plaster casting process, and to allow metal to flow within the part during metal casting.

To ensure the successful creation of your product, make sure supported wires are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a smaller minimum supported wire requirement. If you have bulky areas of a model connected by thin wires, these wires will need to be significantly thicker than the minimum to allow the metal to successfully flow within the model.

Min unsupported wires

1.0 mm thick

A wire is a feature whose length is greater than two times its width. An unsupported wire is connected to walls on less than two sides.

For Silver, the minimum unsupported wire is determined by our ability to successfully print your product in wax, create a plaster mold, and then cast and polish the metal object. Wires need to be strong enough to not break during the wax printing and plaster casting process, and to allow metal to flow within the part during metal casting.

To ensure the successful creation of your product, make sure unsupported wires are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a smaller minimum unsupported wire requirement. If you have bulky areas of a model connected by thin wires, these wires will need to be significantly thicker than the minimum to allow the metal to successfully flow within the model.


0.40 mm high & wide

Min embossed detail

A detail is a feature whose length is less than twice its width. Embossed details stick out from a surface.

For Silver, the minimum detail is determined by the wax printer’s resolution. When detail dimensions are below the minimum, the printer may not be able to accurately replicate them. Details smaller than the minimum may also be lost or warped in the polishing process.

To ensure details come out clearly, make them larger than the indicated minimum. We may be unable to print products with details smaller than the minimum, since the final product will not be true to your design. If your design has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.


0.35 mm high & wide

Min engraved detail

A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.

For Silver, the minimum detail is determined by the casting process. Silver products are printed in wax, and then a liquid plaster is poured around them and solidifies into a mold. When liquid metal is poured into this mold, the pieces of plaster that create engraved details can break off if they are too small.

To ensure details come out clearly, make them larger than the indicated minimum. We may be unable to print products with details smaller than the minimum, since the final product will not be true to your design. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material that can print in finer detail.

Min escape holes

4.0 mm diameter for one escape hole

2.0 mm diameter when there are two or more escape holes

Escape holes allow unbuilt material inside hollow products to be removed.

To create Silver products, a plaster mold is poured around a wax print of your product, and then Silver is cast into the plaster mold. For products with hollow areas, escape holes are essential for two parts of this process. First, the liquid plaster must be able to enter the hole to fill in the hollow area. Then, once the metal is cast, the escape hole must be large enough to allow removal of the hardened plaster from the hollow area. If escape holes are too small, the hollow area may be completely filled in with metal or plaster.

To ensure the successful creation of your product, make sure the escape holes are large enough to allow the plaster to get in and out. Multiple holes make this process easier. If your holes are not big enough, you can enlarge them, add more, or fill in the hollow areas so they are solid. Positioning escape holes at the opposite ends of a product (one on top, one on the bottom) will help the finishing process.

A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.

Clearance

0.3 mm clearance

Clearance is the space between any two parts, walls or wires.

Silver products are printed in wax, and then a liquid plaster mold is poured around them. If the clearance between features is very small, the plaster may not fully infiltrate tiny gaps. Even if it does fully infiltrate the gaps, a plaster wall that is too thin can break when the liquid metal is poured around it. Both issues can cause defects in your product.

To ensure the successful creation of your product, make the clearance between walls and wires greater than the indicated minimum. If your clearance is too small, try making the gap bigger, or consider fusing the features if their independence is unnecessary. You can also try a material with a smaller minimum clearance.
