InssTek MX-Fab DED Metal 3D Printer – 5-Axis DMT Production | 800×1000×700 mm
The InssTek MX-Fab is an all-in-one 5-axis DED metal 3D printer with a 31×39×28 in / 800×1000×700 mm work envelope — a 1,000 W (up to 2,000 W) ytterbium fiber laser, DMT closed-loop melt-pool control, and up to six powder feeders for multi-material and functionally graded parts.
- ✔ 5-axis DED with real-time DMT melt-pool feedback — dense, near-net-shape metal
- ✔ 30+ qualified alloys: Ti, Ni superalloys, stainless & tool steel, CoCr, Cu — multi-material in one build
- ✔ Fabrication, cladding, and repair on one platform
- ✔ Lead time: configured to order — request a quote for delivery & installation
What your process engineer actually checks
Melt-pool control you can trust
DMT's closed-loop vision system measures and corrects the melt pool every layer — density and repeatability without babysitting the machine, and parameter sets that transfer across builds.
An applications engineer on the line
Factory-trained engineers, not a ticket queue. Alloy qualification, DMT parameters, and process troubleshooting in under 24h — we run directed-energy deposition and powder work ourselves. NDA standard.
The InssTek MX-Fab is an all-in-one 5-axis DED metal 3D printer that builds, clads, and repairs dense metal parts up to 31×39×28 in / 800×1000×700 mm — driven by InssTek’s DMT closed-loop process that measures and corrects the melt pool in real time, layer by layer.
Why engineers choose the MX-Fab
Directed energy deposition with closed-loop control — built for production, repair, and multi-material parts.
DMT closed-loop melt-pool control
Coaxial vision cameras measure melt-pool height every layer and adjust laser and powder in real time — dense, repeatable deposits without constant operator tuning.
True 5-axis deposition
An A-axis of −100° to +100° plus a 360° C-axis let the nozzle follow complex geometry and add metal to existing parts — cladding, repair, and near-net-shape fabrication on one bed.
Up to six powder feeders
The CVM feeder runs a standard 2 up to 6 hoppers at 0.05–20 g/min, so you can grade composition mid-build or combine alloys — e.g. an Al-bronze liner inside an Inconel 625 shell.
Inert-gas process integrity
The optional argon chamber holds >99.999% purity at ≤50 ppm O₂ — the oxygen control reactive alloys like titanium need for sound, low-oxide deposits.
How Additive Plus delivers it
Configured to your alloys and parts, installed by engineers who run directed-energy deposition themselves.
Configure to your parts
We size the laser (1,000 W, up to 2,000 W), optics module and feeder count to your alloys and part envelope before you commit.
Install & train on-site
Factory-trained engineers install the system, dial in your first alloys, and train your operators on MX-OS and MiXO Pro.
Qualify & support
We help build DMT parameter sets for your alloys and stay on the line for process development — sub-4h reply, NDA standard.
