Engineering notes on designing, specifying and ordering 3D printed parts, written by the HenleyPrint3D engineering team.
Featured, Design
Layer orientation and part strength, with a worked example
A worked bracket example: the same load needs 8.3 mm lying flat and 11 mm standing up.
Design
Why 3D printed holes come out undersized, and how to dimension them
Holes print 0.1 to 0.4 mm small. Where the error comes from, offsets by process, and ISO 273 clearance sizes.
Materials
Heat deflection: choosing a plastic for under-bonnet parts
What HDT measures, why 0.45 MPa and 1.82 MPa figures differ, and how to pick a printed plastic for a hot engine bay.
