Lights-Out Additive Manufacturing
No operators. No exposure. No downtime.The first SLS 3D printer that prints, cleans, and post-processes entire batches — then starts the next build automatically. Safe for any workshop, no powder room required. Just 24/7, lights-out production.

Meet Prima Materia
The first SLS 3D printer that handles the entire workflow — printing, depowdering, and post-processing — in a single sealed system. No breakout station. No manual labor. No downtime between builds. Just 24/7 lights-out production, safe in any workshop.
Replaces your printer, breakout station, and post-processing line — at a fraction of the combined cost.
The SLS workflow is broken into pieces.
We made it one.
Today's SLS production requires a printer, a separate breakout station, manual depowdering, sieving, and post-processing. Each step introduces labor cost, powder degradation, and safety risk.
Prima Materia streamlines every step of production, so you can focus on what matters most.

Prima Materia
Print, cool, depowder, and post-process — continuously and autonomously under inert atmosphere. One sealed footprint replaces an entire production line.
Need more throughput? Add another unit. Linear scaling, zero added complexity.
One machine. Entire workflow.
Build after build.
Autonomous Print-to-Part
The Prima Materia handles laser sintering, controlled cooldown, depowdering, and post-processing within a single sealed system. Load powder, submit your build file, retrieve finished parts.
Continuous Production
Industry-first back-to-back build capability. When one build volume completes, the next begins automatically. No manual reset, no operator, no downtime between cycles.
Inert Atmosphere
The entire workflow — from sintering through depowdering — occurs under inert gas. Delivering the highest dimensional accuracy and powder reuse rates while eliminating operator exposure.
What Prima Materia Makes Possible
Scale Without Scaling Headcount
Replace a fleet of SLS printers, breakout stations, and dedicated operators with two Prima Materia units running continuous 24-hour cycles. A single technician oversees both.
Projected Outcomes
- 2–3× throughput per machine
- Labor cost per part drops dramatically
- Floor space consolidates
- Higher powder reuse rates
- Capacity for production contracts
The math behind lights-out manufacturing
Every SLS part you produce today carries hidden costs: the operator who babysits the build, the technician who breaks out and sifts powder in open air, the degraded powder you discard after oxygen exposure, the floor space for three machines doing what one should.Prima Materia compresses that entire cost stack.
| Cost Driver | Traditional SLS Fleet | Prima Materia System |
|---|---|---|
| Machines required | Printer + breakout station + post-processing | 1 integrated system |
| Operators per shift | 1–2 per printer | 0 during build cycles |
| Builds per 24 hours | 1 (manual reset between) | 2–3+ (continuous) |
| Powder reuse rate | 50–70% (open-air degradation) | 80%+ (inert atmosphere) |
| Floor space | 3× footprint (multi-machine) | 1× footprint (integrated) |
| Safety overhead | PPE, ventilation, monitoring | Self-contained / sealed |
