A50-HT Metal 3D Printer — AO Metal
A floor-standing LPBF metal 3D printer built around a 900 °C induction-heated build plate, for tool steels and refractory metals that crack on a cooler plate. Ø50 × 100 mm build, 300, 500 or 1000 W fiber laser, water chiller included, 208 V three-phase. Every process parameter open. Designed and built in the USA. Quoted · 8–14 weeks.
What your process engineering lead actually checks
Supported by the team that runs it
We run AO Metal and partner systems daily for our own print services, so install, training, and first builds are handled by engineers who actually operate the machine. When you call support, you reach the team that qualified it.
An applications engineer on the line
Questions on build volume, laser config, throughput, or material compatibility? A named applications engineer scopes it directly — not a sales rep. Most replies in under 4 hours, NDA on request.
- The AO Metal A50-HT printer, Ø50 × 100 mm (2.0 × 3.9 in) build envelope
- A 900 °C induction-heated build plate, as standard
- A water chiller beside the printer
- AO Build Studio software and slicer, with every process parameter open
- Installation and operator training, with a named engineer for your account
- 12-month warranty on laser, scanner, blower, motors and electrical systems
What the A50-HT is
The A50-HT builds the A50’s Ø50 × 100 mm parts on an induction-heated plate that reaches 900 °C, for tool steels and refractory metals that crack from thermal stress on a cooler plate.
Some alloys only print well hot. Tool steels such as H13 and refractory metals such as tungsten, tantalum, niobium and molybdenum build up thermal stress as each layer cools, and crack when the plate below them is cooler. The A50-HT is built around an induction-heated build module: the plate under the part reaches 900 °C, and the temperature is set per job in AO Build Studio. It keeps the A50’s Ø50 × 100 mm build, its fiber lasers and its software, so files and working habits carry over. A water chiller comes with the printer and stands beside it, and the machine runs on 208 V three phase.
How it differs from the A50
- A 900 °C induction-heated build plate, as standard
- A water chiller beside the printer
- A 208 V three-phase input, 60 Hz, for a 60 A circuit
- The same fiber lasers: 300, 500 or 1000 W
- Blue laser: for copper, gold and silver choose the A50
- Glove-port door
- Build volume reducer

Materials: made for the alloys that need heat
The A50-HT runs the A50 alloy list except the metals that need the blue laser. The list is open: for an alloy we have not run yet, our process engineers develop and validate the parameters and hand over the program.
| Tool steels | H13, M300 |
| Refractory metals | W, Ta, Nb, Mo |
| Stainless steel | 316L, 17-4PH |
| Nickel alloys | Inconel 625, 718 |
