Fundamentals
3D printing limitations — what to know before ordering
Layers, supports, tolerances, shrinkage and surface finish — practical constraints worth considering while the part is still being designed.
Design
3D printing tolerances and fits — a practical guide
How to design holes, clips and mating components so that printed parts actually assemble and move as intended.
Design
Orientation, layers and infill — what really strengthens a print
How build direction, wall paths, layer height and infill affect strength, appearance, weight and production cost.
Guide
How to prepare a model for 3D printing
Walls, supports, scale, tolerances and file formats — a complete checklist before submitting a model for a quote.
Materials
Choosing material for a functional part
PLA, PETG, ASA, ABS or TPU? Match material to temperature, load, environment and how the part will be used.
Technology
FFF or SLA — which technology should you choose?
A practical FFF/FDM and SLA comparison covering detail, finish, strength, size, supports and post-processing.
