A100-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. Ø100 × 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 A100-HT printer, Ø100 × 100 mm (3.9 × 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 A100-HT is
The A100-HT builds on a Ø100 × 100 mm plate, four times the area of the A50-HT, heated by induction to 900 °C — for nested builds and short series in crack-prone alloys such as tool steels and refractory metals.
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 A100-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 A100’s Ø100 × 100 mm build, four times the A50-HT plate area, with the same fiber lasers and software, so a process proven on the A50-HT moves up as a file. 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 A100
- 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 A100
- Glove-port door
- Build volume reducer

Materials: made for the alloys that need heat
The A100-HT runs the A100 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 |

| Cobalt chrome | CoCr |
| Copper alloy | CuCrZr, on the fiber laser |
| Research alloys | NiTi, Fe-Co-V, magnesium, high-entropy alloys |
Pure copper and precious metals need the blue laser: choose the A100.

What else you need to run it
Argon, a wet vacuum cleaner (explosion-proof for reactive metals) and a powder sieving machine. A heat-treatment furnace, a band saw or small lathe and polishing tools are recommended for finishing. The configurator puts the whole set together and plans it in your room.
