PRINT INTELLIGENCE · ADAPTIVE THERMAL CONTROL

Every layer under control.
Scrap is a thing of the past.

Print Intelligence combines computer vision with thermal imaging of every layer. A defective part is masked automatically — without ruining the whole build. Adaptive Thermal Control keeps the temperature field stable across the entire chamber.

  • 13 independent thermal zones — Adaptive Thermal Control
  • 700× more thermal data/s than the Fuse 1+ 30W
  • Automatic masking of a defective part without stopping the build
  • Installation in ~1 hour · job changeover in 5 minutes

FAQ

Fuse X1 questions & answers.

How much does the Formlabs Fuse X1 cost in Ukraine?

The starting US price is from $84,999 per printer (according to Formlabs). The price in Ukraine is available on request: we accept pre-orders, with shipping expected from Q4 2026. Request a quote.

When will Fuse X1 shipments begin?

Expected from the fourth quarter of 2026. Ask us for exact lead times for Ukraine — pre-orders are already open.

What is the Fuse X1 build volume?

330 × 330 × 565 mm (61.5 liters). The maximum part length along the diagonal is 713 mm.

How does the Fuse X1 differ from the Fuse 1+ 30W?

A 7.5× larger volume (61.5 L vs 8.2 L), a 120 W laser vs 30 W, 5.2× higher throughput, Print Intelligence with 13 thermal zones, and a 5-minute job changeover.

Which materials does the Fuse X1 support?

At launch — Nylon 12 (PA12). By the end of 2026 — Nylon 11. By June 2027 — Nylon 12 GF and TPU 90A. Open Material Mode opens up any 1064 nm powder.

Does the Fuse X1 require nitrogen?

Yes, printing takes place only in a nitrogen atmosphere (N₂): a nitrogen generator or cylinder supply is required. Factor this into the installation budget — our engineers will help you choose a solution.

What is Print Intelligence?

A quality-control system: computer vision + thermal imaging of every layer. A defective part is masked automatically without ruining the whole build. It works together with Adaptive Thermal Control (13 zones, ×700 thermal data/s).

Where can I buy the Fuse X1 in Ukraine?

LLC 3Dprint (3Dprint.ua) is an authorized Formlabs partner in Ukraine, based in Kyiv. The status is confirmed on the official Formlabs partner map. Phone: +38 095 66 168 66.
