•If a bridge exceeds 5mm, sagging or marks from support material can occur. Splitting the design or post-processing can eliminate this issue.
•For critical vertical-hole diameters, drill after printing to achieve higher accuracy.
•The addition of support will allow FDM printers to print wall angles greater than 45°.
•Include a 45° degree chamfer or radius on all edges of an FDM part touching the build plate.
•For applications with small vertical pins, add a small fillet at the base or consider inserting an off-the-shelf pin into a printed hole instead.
•Splitting a model, reorienting holes and specifying build direction are all factors that can lower cost, accelerate the printing process and improve a design’s strength and print quality.
