Small, medium and large FDM 3D printers

Quick answer

A small FDM printer suits desk-sized parts; medium sits around the 30 cm class and large approaches 45–50 cm projects. These are browsing groups, not strict cutoffs. The final fit depends on the three dimensions of your part and the exact machine.

Start with the part

Measure width, depth and height of the finished part. Test its orientation in a slicer and leave room for supports and a brim. Small, medium and large help you explore; they never replace X×Y×Z measurements.

How large is your part?

Three scales to start with. The exact dimensions are always in the profile.

Practical guides

Build volume is not the machine footprint. Allow space for the spool, cables, ventilation and bed travel.
