On 9 June 2026 Formlabs unveiled the Fuse X1 — a large-format industrial SLS printer. It genuinely lowers the barrier to entry: a technology until now reserved for large contract manufacturers becomes available to mid-sized production companies. As an authorized Formlabs partner, we explain what this machine is, how it relates to SLA printing (Form 4L) and how to choose the right solution for real tasks — without overpaying and without buying "for show".

What Formlabs announced

The Fuse X1 is a selective laser sintering (SLS) ecosystem for producing functional parts in short and medium runs. Key declared specs (per Formlabs and industry media):

  • Build volume: 330 × 330 × 565 mm.
  • Packing density: over 30% of the chamber volume, versus the 10–15% typical of MJF.
  • Throughput: production-quality parts in under 24 hours, up to half the cost per part and triple the throughput of comparable systems.
  • Availability: orders open, first deliveries in Q4 2026.
  • Installation: fits through a standard door, single-phase power without special HVAC, setup in about an hour.

SLS or SLA? The Fuse X1 alongside the Form 4L in the Formlabs ecosystem

This is the question we hear most from clients. The two Formlabs technologies complement rather than compete with each other:

  • SLA (Form 4L) — large-format resin, top accuracy and smoothness. Ideal for visual prototypes, casting patterns, parts with high aesthetics.
  • SLS (Fuse X1) — nylon powder, support-free printing, durable functional parts and real series. For end-use parts: jigs, housings, tooling, spare parts.

In short: need a perfect surface and detail — SLA; need strength and series production — SLS. The choice depends on the part, not on trends.

Who benefits from an in-house SLS

Cheaper industrial SLS does not mean "for everyone". An in-house machine pays off with a steady, regular workload and requirements for speed and confidentiality (everything stays with you). For irregular, one-off batches it is wiser to start with print-on-demand and move to your own equipment once volume becomes predictable. First calculate your real monthly parts volume — only then decide on a purchase.

Why buy from an authorized Formlabs partner

The hardware itself is just the start. As an authorized Formlabs partner we provide what really determines the return on investment:

  • Task-based selection — we help assess whether the Fuse X1, the Form 4L or print-on-demand is the cheapest route to your goal.
  • Genuine hardware and warranty — full manufacturer support, materials and consumables.
  • Onboarding and training — installation, first prints, post-processing, powder handling.
  • Technical support — because in production, response time matters, not just the machine price.

That is the difference between "buying a printer" and "launching a working production line".

Summary

The Fuse X1 signals a broader trend: industrial SLS is getting cheaper and entering mid-sized companies. But "more accessible" is not "needed by everyone" — base the decision on workload, control and the real cost per part. Start with a conversation about your task: we will match the technology and equipment that actually pay off.

Frequently asked questions

Fuse X1 (SLS) or Form 4L (SLA)?
SLA — top detail and smoothness (prototypes, aesthetics). SLS — durable functional parts and series. The specific part decides.

When is the Fuse X1 available?
Orders open, deliveries announced for Q4 2026 (Formlabs data, June 2026).

Why buy from an authorized partner?
Genuine hardware, manufacturer warranty, onboarding, training and fast technical support — these determine the real return on investment.
