Built to order. Designed around your needs.
The Monster Kossel is our fully customizable, large-format Delta 3D printer. Unlike off-the-shelf machines, it is tailored to your requirements — size, materials, and performance — making it ideal for businesses, labs, and advanced users who need more than standard equipment can offer.

Why choose The Monster Kossel?

- Scalable design
Built as a Delta-type printer, the Monster can be resized to suit your requirements – whether you need extra height, larger build volumes, or a compact but powerful unit. - Precision at scale
Even with tall prints, Delta mechanics keep the part stable for consistent accuracy. - Flexible extrusion system
A lightweight print head with remote motor allows for direct extrusion without slowing movement. The result: faster printing and better control with flexible or high-performance filaments. - Custom enclosure options
Choose a closed, heated chamber with filtered ventilation for advanced materials, or keep it open for standard work. - Advanced cooling
Options include air-cooled or water-cooled nozzles depending on your setup. - Silent operation
Engineered to be quiet enough to run in offices, labs, or workshops without disruption.
What makes it different?
- Made-to-measure: Each Monster is designed and assembled based on your specifications.
- Component flexibility: We select the best components on the market, independent of any single supplier.
- Future-proof: Open-source foundation means your machine can be upgraded or modified as your needs evolve.
- Swiss expertise: Designed and assembled in our Gland workshop, with full after-sales support.
