Design Guidelines

List of requirements to ensure successful printing and put your mind at ease.

Kindly select materials according to your requirements. Please check the properties of materials. Visit Materials for more information.

Check the thickness of your design. Every part of your model must be thick enough to be printed, survive post-production, and be safely packed and shipped. Please check the thickness design requirements for different materials.

Minimum Wall Thickness

Minimum wall thickness are the thinnest that your model can be on any given supported or unsupported walls. Please refer to below guidelines. Parts that does not meet the guidelines might warp or detach from the model during printing. Please increase the thickness or select different materials.

 

Supported Wall


Walls that are connected to other walls on two or more sides.

Minimum Escape Hole Diameter

Recommended: > 2.0 mm Diameter

Prepare at least one escape hole for hollow model so that excess material can escape during 3D Printing process. It is best to have multiple escape holes at different locations so that excess material near the hole can be remove.


Minimum Vertical Post Thickness

In the model, post is the protruding part whose length exceeds 2 times the width (embossed detail is when length less than 2 times the width). Parts that does not meet the guidelines might warp or detach from the model during printing. Please increase the thickness or select different materials.

 

Supported post is when both ends are connected to wall

Unsupported post is when one end connected to wall

Minimum Unsupported Overhang Angle


Recommended: >20° from level

If there is an overhang angle in your design, the angle of this part needs to meet the minimum requirements or else it would break off the model during peeling, post-processing or delivery.

 

Minimum Clearance


Clearance is the distance needed between two connecting or moving parts of a model. Support might not be removed if clearance less than the required distance.
