About this product
The Farsoon Flight HT601P-4 is a large-format, quad-fiber SLS system built for speed and detail: four 300 W fiber lasers — 1,200 W total — scan a 600 × 600 × 600 mm cubic build at up to 20 m/s, with a 220 °C chamber for engineering polymers. Efficiency and Quality scan modes plus adjustable laser spot size tune each build for throughput or fine detail. It pairs an open platform with an interchangeable build cartridge and an Advanced Powder Management System for continuous production. Debuted at Formnext 2024. Sold, installed and supported in the US by Additive Plus.
Why production teams choose the Flight HT601P-4
Quad-fiber speed and detail on a large cubic bed — with open process control.
Cubic 600 mm build volume
A 600 × 600 × 600 mm cube — 23.6 in per side, 216 L — prints tall or bulky single parts and dense nested batches that a 400 mm system can’t fit.
Quad 300 W fiber lasers
Four 300 W fiber lasers — 1,200 W total — scan the 600 mm bed in parallel at up to 20 m/s (66 ft/s) for high-throughput production.
Efficiency & Quality modes
Adjustable laser spot size plus Efficiency Mode (overlapping lasers for speed) and Quality Mode (single-laser for fine detail) tune each build for throughput or precision.
Open platform, continuous production
Full parameter control with an interchangeable build cartridge, an Advanced Powder Management System that recycles, mixes and sieves powder, and smart production-line integration.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What size parts can the Flight HT601P-4 build?
The Farsoon Flight HT601P-4 has a 600 × 600 × 600 mm (23.6 × 23.6 × 23.6 in / 216 L) cubic build volume — a full 600 mm in every axis, so it handles tall or bulky single parts and dense nested batches that a 400 mm-class SLS system can't fit. The cubic envelope suits large housings, ducts and high-nest production runs.
How many lasers does the Flight HT601P-4 have and how fast is it?
The Flight HT601P-4 uses four 300 W fiber lasers — 1,200 W total — scanning in parallel at up to 20 m/s. Efficiency Mode overlaps the lasers' scan fields for maximum build speed, and an interchangeable build cartridge lets one build cool and unpack while the next runs, keeping the machine in near-continuous production.
How is the Flight HT601P-4 different from the CO₂ HT601P-2?
Both share the 600 × 600 × 600 mm cubic build and 220 °C chamber. The Flight HT601P-4 uses four 300 W fiber lasers with adjustable spot size and Efficiency/Quality scan modes — faster scanning and finer detail; the HT601P-2 uses dual 100 W CO₂ lasers and is positioned as the lower-cost option. Choose the HT601P-4 for speed and detail, the HT601P-2 for cost-efficient volume.
What materials can the Flight HT601P-4 run?
The Flight HT601P-4 runs PA12 and PA11 nylons for general functional parts, PA6 for higher heat and stiffness, PBT as an engineering thermoplastic, and TPU for flexible parts. Because it is an open platform, Additive Plus can help qualify additional SLS powders and supply validated parameters for each material you plan to run.
Is the Flight HT601P-4 an open or closed material system?
The Flight HT601P-4 is a fully open platform. You control laser, scan and thermal parameters through Farsoon's BuildStar and MakeStar® software, and you are not locked to a single powder supplier. Additive Plus helps you develop and validate profiles for third-party or custom powders so you can optimise cost and part performance.
What are Efficiency and Quality scan modes?
Efficiency Mode overlaps the four fiber lasers' scan fields for maximum build speed on large or high-nest jobs. Quality Mode uses a single laser for the finest surface detail and edge accuracy. Combined with adjustable laser spot size, you can bias each build toward throughput or precision without changing machines.
What does delivery, install and support look like?
Additive Plus sells, installs and supports the Flight HT601P-4 in the US: site and power planning, commissioning, operator training on BuildStar / MakeStar®, validated material profiles, and local warranty and service. Lead time is configured to order — request a build slot and a named engineer will confirm timing and configuration.
