BOUNDING BOX
Maximum
284 x 380 x 380 mm
Minimum
X + Y + Z ≥ 9.0 mm
7.0 x 7.0 x 7.0 mm
Your model should be the minimum and maximum bounding box sizes. The maximum bounding box represents the largest model that that we can manufacture. The minimum bounding box size is the smallest dimension in which we can manufacture in this material.
WALL THICKNESS
Minimum Supported Wall Thickness
0.75 mm
Minimum Unsupported Wall Thickness
1.0 mm
A supported wall is connected on two or more sides. An unsupported wall is one connected to other walls on less than two sides. Walls in your model should be thicker than or equal to the minimum measurements suggested to ensure your model makes it through printing and cleaning. Walls that are too thin are prone to warping in the printing processing, or may break when we remove it from the printer and clean it.
Walls and wires close to or slightly above the guidelines may still be rejected based on the geometry. For example, extra long wires or walls protruding from an object may be damaged during cleaning. Our production team will communicate with you if the design is too weak with tips on how to strengthen it.
WIRES
Minimum Supported Wires
1.0 mm
Minimum Unsupported Wires
1.0 mm
A geometry considered a wire when its thinner in both unconnected directions than its length. Wires that are under our suggested minimums are prone to breaking in the cleaning process, or warping.
SURFACE DETAILS
Min embossed detail
0.5 mm high & wide
Min engraved detail
0.5 mm high & wide
We recommend these minimum measurements for details like embossing or engraving, based off of printer resolution.
ESCAPE HOLES
Single Escape Hole Diameter
4.0 mm
Multiple Escape Hole Diameter
2.0 mm
Pressurized air is used to blast excess powder from models that are hollow, or contain hollow cavities. In order for us to safely do this, escape holes need to be larger than 4.0 mm in diameter. For models larger than 50.00 mm³ we require two or more escape holes at least 2.00 mm in diameter.
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
0.6 mm
Clearance is the space between two parts, e.g. space between gears or a ball and socket joint.
SPRUES
2 mm thick, attached in at least 2 places per part
Sprues are wires that keep two models together. Sprues are more likely to break compared to other wires because they typically connect parts with high mass on either side. For this reason, they need to be thicker than our minimum wire thickness.
INTERLOCKING AND ENCLOSED PARTS ?
Yes.
PA12 Glass Beads Plastic is printed with a powder bed process fusing together nylon powder. This enables interlocking parts, as long as the distance between them is greater than the indicated minimum.
MULTIPLE PARTS ?
Up to 250.
ACCURACY
±0.25 mm + 0.2% of the longest axis
For example: a product with dimensions of 50x50x100 mm can be 0.25 mm + 0.002*100 mm = 0.2 mm bigger or smaller in any direction.
DESIGN TIPS
Print lines or "Stepping"
A "staircase" effect, or print lines, can occur on the surface of your print. These can become more pronounced on curved and angled surfaces.
Preventing Warping
Making your design more stiff (increasing torsional rigidity) will reduce the risk of warping. Longer walls need to be thicker than short ones.
Avoid "Spikes"
If your model has spike-like geometry where the spike is longer than it is wide, it’s possible for it to break in the cleaning process.
Orientation
Our production team does their best to evaluate your product and orient it to optimize either dimensionally accuracy or aesthetics depending on the application. Generally, the top surface will have more visible stepping than the bottom surface. The mating surface and other important features like holes are the most accurate when placed in the horizontal plane.
Holes & Small Holes
We cannot clean holes that are too small compared to their depth. Additionally, tubes with corners can be difficult to reach and we may not be able to fully clean your model.
We recommend creating multiple access points to holes and small tubes so that we can properly clean your model.
