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.

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

Comes with

  • A 900 °C induction-heated build plate, as standard

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
Titanium Ti-6Al-4V, TiAl
Aluminum AlSi10Mg, 6061
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.

Who it is for

ToolingH13 inserts and dies with conformal cooling, printed on a plate hot enough to keep them from cracking.
Refractory metalsTungsten, tantalum, niobium and molybdenum parts and test coupons for high-temperature research.
Materials researchCrack-prone and experimental grades, with the plate temperature as one more parameter to study.
Short seriesNested builds on a Ø100 mm plate, for small batches of parts that need a hot plate.

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.

Common questions

Don't see yours? Email [email protected] — NDA on request, typical reply within 4 hours.

When do we need the A100-HT rather than the A100?
When the alloy cracks from thermal stress on the A100’s 250 °C plate: some tool steels such as H13, and refractory metals such as tungsten, tantalum, niobium and molybdenum. For steels, titanium, nickel alloys and aluminum the A100 is enough.
Why is there no blue laser?
The HT printers are built around the induction-heated build module and run the fiber laser. Copper, gold and silver need the 455 nm blue laser, which is offered on the A50 and A100.
What power supply does it need?
208 V three phase, 60 Hz: three lines and ground, no neutral, from a 60 A circuit through an IEC 60309 60 A pin-and-sleeve receptacle, or hardwired. By our estimate the printer peaks at about 12.8 kW with the chiller, most of it the induction generator at full output; about 1 kW for the heated plate while printing.
How much space does it take?
The printer is 1890 × 810 mm and 1950 mm tall. With the monitor arm out it takes 1890 × 1160 mm of floor, and the arm comes off to pass a 32-inch door. It weighs 750 kg, and the water chiller beside it is 750 × 560 mm, 1020 mm tall, 85 kg.
How is it priced?
In a formal quotation with the configuration, price, payment terms and lead time. Tell us the alloy and the part, or put the configuration together in the AO Metal configurator.
What do installation and warranty cover?
Installation and operator training are included, with a named engineer for your account. The warranty covers laser, scanner, blower, motors and electrical systems for 12 months.
