Design Guidelines for Alumide

The rules to follow in order to create successful products in Alumide. Read more on model checks
Max bounding box 230 × 180 × 310 mm 150 × 150 × 150 mm

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

For unpolished Alumide, 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 consider another material with a bigger maximum bounding box.

For Polished Alumide products, the maximum bounding box is limited by the size of our polishing machines. 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 X + Y + Z ≥ 7.5 mm X + Y + Z ≥ 25 mm

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

The minimum bounding box is determined by the printer's ability to successfully print very tiny models.

To ensure the successful creation of your product, make sure the bounding box of your model 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.

Design tips

Prevent walls from warping on larger models

Large models with thin walls may warp depending on the geometry of the part. Because this material is flexible, bigger parts with thin walls will droop due to gravity. Longer walls need to be thicker than short ones.

Min supported wall thickness 0.8 mm thick 1.0 mm thick

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

For unpolished Alumide, 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 often break when the product is removed from the powder bed, or when excess dust is removed from the product. To ensure the successful creation of your product, make sure the supported walls are thicker than the minimum requirement. If they are not, try making them thicker, or consider a material with a smaller minimum supported wall requirement.

For Polished Alumide products, the minimum supported wall is determined by our ability to successfully polish your product once it has been printed. Walls that are too thin are broken by the pellets in our polishing machines. 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 smaller minimum supported wall requirement.

Min supported wires 1.3 mm thick 1.5 mm thick

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

For unpolished Alumide, 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 often break when the product is removed from the powder bed, or when excess dust is removed from the product. 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 embossed detail 0.70 mm high & wide 0.80 mm high & wide

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

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. Details that are too small can also be smoothed over in the polishing process. 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.

Design tips

Polishing will wear down and dull sharp details

The 5mm cylindrical pellets we use as polishing media can remove up to 0.1mm material from the surface of your model. With small details, this can rub away sharp corners and make them look less crisp.

Thicken your engraved/embossed text to make it easier to read

Although 0.2mm details will show up in this material, we find that text raised at least 0.5mm shows up most clearly. If you want crisper text or embossed details, try bumping the thickness up to 0.5mm.

Min engraved detail 0.70 mm high & wide 0.80 mm high & wide

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

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.

Min escape holes 4.0 mm diameter for one escape hole


2.0 mm diameter when there is two or more escape holes
Required in products bigger than 50x50x50mm

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

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. This is especially important for our water-based dyeing process â?? models cannot be successfully dyed if they cannot be successfully cleaned inside and out. 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 0.5 mm clearance

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

Alumide is printed with an SLS process that uses a laser to fuse together nylon powder. When there is a very small gap between features or parts, partially fused powder can get stuck in between. This can prevent mechanical parts from moving, or fill in intended gaps between features.

To ensure a successful product, make the clearance between parts, walls, and wires 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.

Interlocking and enclosed parts? Yes.

Alumide is printed with an SLS process that uses a laser to fuse together nylon powder. This enables interlocking parts, as long as the distance between them is greater than the indicated minimum.

Multiple parts per model file? Yes, up to 16.
Accuracy ± 0.15 mm, then ± 0.15 % of longest axis

Material Traits
Some detail is lost during polishing

The polishing media can take off up to 0.1mm of the surface. For small details, this can rub away the sharp corners of your details and make them less crisp

Material Info

Look and feel

Alumide is Nylon Plastic filled with Aluminum dust. This dust gives Alumide the sparkle, but also makes the material more brittle than the Strong & Flexible material.

Print It Anyway
We are piloting a new way for you to bring experimental products to life. With Print It Anyway, you will receive a 3D print in your hand, even if your model does not meet our design guidelines. Learn more about Print It Anyway.

All Alumide finishes are eligible for Print It Anyway.

Handling and care
This material
  • is dishwasher safe
  • not watertight
  • not recyclable
  • not foodsafe

Alumide is heatproof to 172�ºC / 342�ºF degrees. Higher temperatures may significantly change material properties.

How it's 3D printed

We start with a bed of mixed Nylon Plastic and Aluminum powder. We sinter the powder with a laser layer by layer, solidifying the powder as we go. Because of this layer by layer process, some models may see a staircase effect. How much you see this effect depends on how your model is oriented in the print tray. Our production planners are working hard to orient models optimally to ensure efficient and good lookin' trays.

We also offer Polished Alumide, which is a smoother version of Alumide. This material is great for jewelry or anything that needs a futuristic look. It gives your model a matte metallic-like finish at a lower price than our Stainless Steel and Silver materials.
