Farsoon Flight® 403P SLS 3D Printer – Fiber-Laser High-Performance Polymer | 400×400×450 mm
Fiber-laser SLS system: a 500 W fiber laser with dynamic optics drives build rates up to 6 L/h with a fine ~100 µm contour spot, on a 15.7×15.7×17.7 in / 400×400×450 mm build (up to 540 mm tall). Built for high-performance polymers and demanding production, with fully open parameters. Sold, installed and supported in the US by Additive Plus.
- 500 W fiber laser — up to 6 L/h, ~100 µm contour for crisp features.
- High-performance polymers — PA-F nylons, glass-bead, LUVOSINT TPU; chamber to 220 °C.
- Lead time: configured to order — US install, training & validated profiles from California.
What your process engineer actually checks
Fiber-laser speed with fine contours
The Flight® 403P's 500 W fiber laser and dynamic optics push build rates to 6 L/h while a ~100 µm contour spot holds crisp edges — speed and detail that a CO₂ system can't match together. On an open platform, you control and validate the process rather than accept a locked recipe.
An applications engineer on the line
Pre-sale help choosing materials and fiber-laser settings, post-sale troubleshooting, and a demo or sample build before you commit. We run SLS ourselves — sub-4h reply, NDA on request.
The Farsoon Flight® 403P replaces the CO₂ laser of a standard SLS system with a 500 W fiber laser and dynamic optics — driving build rates up to 6 L/h with a fine ~100 µm contour spot on a 15.7 × 15.7 × 17.7 in / 400 × 400 × 450 mm build (up to 540 mm tall). It targets high-performance polymers and demanding production parts, with fully open parameters. Sold, installed and supported in the US by Additive Plus.
Why production teams choose the Flight® 403P
Fiber-laser SLS — speed and fine detail together, on an open platform.
500 W fiber-laser speed
A single 500 W fiber laser with dynamic optics drives build rates up to 6 L/h and scan speeds to 20 m/s — a clear step up from CO₂ for production throughput.
Fine ~100 µm contour
A ~100 µm contour spot (≈550 µm fill) resolves crisper edges and finer features than a CO₂ system, while the fill beam keeps the interior fast.
High-performance polymers
PA-F nylons, glass-bead nylon and LUVOSINT® TPU, with chamber temperatures to 220 °C — built for demanding, functional production parts.
Open-parameter platform
Full control of laser, scan and thermal parameters via BuildStar / MakeStar® — develop and qualify your own process, not a locked recipe.
How Additive Plus delivers your Flight® 403P
A fiber-laser SLS system is only as good as the team behind it — here’s how we set you up.
Configure & qualify
We spec the right chamber temperature and build height for your parts and materials, and help qualify the powders you plan to run on the open platform.
Install & train
US-based installation, US power sorted with the supplied transformer, and operator training on BuildStar / MakeStar® — commissioned in your facility.
Validated profiles & support
Proven fiber-laser parameter sets for your materials, application and DfAM guidance, and local warranty and service — a named engineer replies within 24 hours.
