A30 Metal 3D Printer — AO Metal
Every laser parameter is yours — no cartridges, no annual licence, no locked recipes. A test build costs about 71 g of 316L. Fully open material system: the machine runs any metal powder you qualify, and we supply validated parameters for the standard alloys. Desktop LPBF, Ø30 × 60 mm (1.2 × 2.4 in) build, 200 W laser (300 W optional), 120 V. Designed and built in the USA. From $59,000 · 8–14 weeks. Installation and commissioning in the USA: facility and gas planning, start-up and operator training by our US service team.

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.

What the A30 is
The A30 is an entry-level benchtop laser powder bed fusion printer: a fiber laser melts metal powder directly into fully dense parts in one step. It is built for the work that comes before production — developing an alloy, dialling in a process window, printing test coupons, and teaching students what those parameters actually do. It runs from a dedicated 120 V single-phase, 50 A circuit with argon under 2 L/min, so it installs in an ordinary laboratory rather than a machine hall.

What a trial actually costs in material
This is the number laboratories ask for and rarely get. For a build of test coupons 10 mm tall:
| Stainless 316L | 71 g |
| Ti-6Al-4V | 41 g |
| Aluminium AlSi10Mg | 25 g |
| CoCr | 77 g |
| Copper | 81 g |
A full-height build takes about 453 g of 316L or 260 g of titanium, and the metal that ends up in a 10 mm cube is 7.9 g. Trying a new alloy here is a question of grams, not kilograms — which is what makes parameter development affordable at all.
Fully open — and we mean the parameters
- Laser power, scan speed and strategy
- Hatch spacing and layer thickness
- Contour and infill exposure — per zone, so different regions of one build can run different settings
- Your own parameter sets, stored in AO Build Studio
- No cartridges and no chipped powder
- No approved-material list
- No annual software subscription
- No permission needed to run a powder you bought or developed yourself
The machine also arrives with the parameter sets our team has already validated — and if your alloy is not in that set, we develop the parameters and hand the program to you. Changing material takes about an hour, so a laboratory can move between alloys within the same day.
Where the A30 stops — and what to take instead
Two things are not available on the A30, and it is better to know now than after the order. The 455 nm blue laser is offered on the A50 and the A100, and a 900 °C build plate on the A50-HT and A100-HT only. The blue laser is what makes copper, gold and silver workable, because those metals absorb blue light far better than infrared. And the build envelope is Ø30 × 60 mm (1.2 × 2.4 in): if your parts are larger, the A50 at Ø50 × 100 mm (2.0 × 3.9 in) or the A100 at Ø100 × 100 mm (3.9 × 3.9 in) carry the same open platform.
Make your own powder, measure it, print it
We are the US distributor for ATO ultrasonic atomizers and for Microtrac particle analyzers including the Camsizer X2. Put them next to the A30 and the loop closes inside your own laboratory: atomize your material into spherical powder, measure particle size distribution and morphology, print, repeat. When you would rather not run that part yourself, we make custom alloy batches in three to four weeks.
