Overview FDM Resin

// FDM methodology

How we test FDM printers.

Filament machines live or die on consistency over long jobs. Here is the exact rig, the materials and the test models we use to score every FDM printer on the site.

// Materials

What we print on every machine

We run a fixed set of filaments from the same batches across every printer, so material is never the variable.

// The test suite

Six prints, one verdict

// The rig

Controlled, repeatable conditions

Every printer runs in the same room at a held ambient temperature, on the same power, with the same filament batches. We measure rather than eyeball: digital calipers for accuracy, a decibel meter at half a metre for noise, and timed logs for setup and print duration.

We test with stock profiles first, because that is what most buyers use, then note how much tuning a machine needs to reach its best.

FDM scoring priorities

All fourteen benchmark metrics apply, but for filament machines these five do the heaviest lifting in the final score.
