Blocks RF50: built to produce big
The Blocks RF50 was designed for the fast production of large-scale, high-precision parts. The large print volume lets you create complex, large components faster.
Designed for demanding environments, it offers durability and compatibility with a wide range of advanced materials: ideal for aerospace, automotive, engineering and product design.

Blocks RF50: speed without losing quality
- Print Core: high-throughput print cores
- Active resonance compensation: reduces ringing even at maximum speed
- Bondtech LGX Lite extruder, with filament tension in 3 positions
- CAN bus communication, continuous and synchronised
- Filament cutter with sensor, for quick material changes
Advanced print platform
- Automatic bed levelling
- True Z-axis levelling at all four corners
- Flexible metal plate, to remove parts easily
- Even temperature distribution, for good adhesion


Think big, move faster
Large part: 347 × 131 × 4.8 mm in PETG, 0.16 mm layer, 6 h 34 min, 188 g.
Series production: 64 parts of 40 × 40 × 10 mm in PLA, 0.2 mm layer, 20 h 7 min in total (18 min 54 s per part), 4 g each.
