Ethan writes about choosing between machined and extrusion-printed parts. His topics include aluminum and POM machining, ABS and PETG printing, tool access, corner radii, tolerances, inserts and assembly features. He builds articles around drawings and use conditions, explaining how process choice changes cost, finish and fit, and which dimensions or loads should be checked before committing to production.
