Voron
Voron 2.4 r2 (self-build) review
Not a product — a documented open-source design you source and build yourself. The most capable machine on this list if you enjoy the build as much as the printing.
Best for: Experienced makers who want to build, not buy.
What we like
- Fully open, infinitely modifiable
- Quad gantry levelling is genuinely excellent
- Every part documented and replaceable
What we don't
- A 20–40 hour build with no support line
- Kit quality varies wildly by vendor
- You are your own warranty

Specifications are the manufacturer's published figures. "Max speed" is a headline number no printer sustains across a whole part — treat it as a ceiling, not a throughput estimate.
