Drafting with 3D Printing in Mind

Posted by LGM | Friday, September 20th

These 3 considerations should be in your mind while drafting for 3D printing

To produce a set of printed 2D construction drawings, certain preparation must be made; layouts arranged, sheets put in order, print jobs configured, etc. Similarly, to 3D print a model, certain steps must be taken to ensure a successful outcome.

Tolerances  If it is too small for the 3D print technology you choose, it will break.

The first order of consideration is referred to in the industry as print tolerance. Tolerance, as it applies to 3D printing, is how small a detail can successfully be 3D printed and survive the process. Every 3D printer has a different tolerance, so there is no definitive rule for how small a detail can be on a 3D printed part. There are several factors in determining the appropriate adjustments to make to a model to get the tolerances right such as level of detail desired, scale of printed model, the model's native CAD format, and printing technology, to name a few.
