Guides, comparisons,
and things worth knowing.
Long-form explainers on materials, print technologies, cost, and where to find printable files. Written by the people running the machines.
3D printing materials: the complete guide
PLA, PETG, ABS, TPU — how they behave, where they fit, and how to pick between them.
ComparisonPLA vs PETG: which filament should you use?
Detail, toughness, temperature resistance, and printability compared side by side.
ComparisonPLA vs ABS: strength, heat, and post-processing
When ABS's higher temperature ceiling matters and when PLA's easier print wins out.
