In-Depth Information
• Do your parts require fully dense wall thicknesses (with the additional material cost
and weight) or is a latticework interior acceptable?
• Space multiple parts to make the most economic use of the 3D print material.
• Ensure 3D model surfaces are watertight; that is, complete with no gaps. Objects
cannot have open faces.
• Are parts balanced? Is it possible to understand where the centre of gravity is?
• When printing assemblies, leave sufficient gaps between moving parts. Also ensure
two separate objects do not share a common edge, instead always leave a gap.
• Carefully consider scale and sizing. Smaller scale models use less material and cost
less. Ensure your parts can fit within the print envelop. Larger prototypes can be as-
sembled from a range of smaller 3D printed parts, which are then screwed or glued
