What your process engineer actually checks
Dual fiber lasers, fastest 403-class throughput
Two 300 W fiber lasers scan in parallel to push build rates to 9 L/h — the highest in the 403 class. For a production floor, that throughput is the difference between meeting a volume commitment and outsourcing it. On an open platform, you keep control of the process while running fast.
An applications engineer on the line
Pre-sale help choosing materials and dual-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-2 is the highest-throughput system in the 403 class: two 300 W fiber lasers scanning in parallel push build rates up to 9 L/h on a 15.7 × 15.7 × 17.7 in / 400 × 400 × 450 mm build (up to 540 mm tall). It’s built for serious polymer production, running high-performance nylons and TPU with fully open parameters. Sold, installed and supported in the US by Additive Plus.
Why production teams choose the Flight® 403P-2
Dual fiber lasers for the fastest 403-class throughput — with process control you keep.
Dual 300 W fiber lasers
Two fiber lasers scan in parallel for build rates up to 9 L/h — the highest throughput in the 403 class, for teams whose priority is volume.
Serious production throughput
A 400 × 400 × 450 mm build (up to 540 mm tall) with scan speeds to 20 m/s — sized and paced for repeatable batch production.
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-2
A dual-laser production SLS system is only as good as the team behind it — here’s how we set you up.
Configure & qualify
We spec the chamber temperature and build height for your parts, and help qualify the powders you plan to run on the open dual-fiber 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 dual-laser parameter sets for your materials, application and DfAM guidance, and local warranty and service — a named engineer replies within 24 hours.
