While the desktop world argues about budget bed slingers, the industrial side of 3D printing had a busy week of its own. Two new production systems debuted, reported in 3DPrint.com's June 6 news brief: a six-figure metal printer from Mastrex and a benchtop SLS machine from Sinterit. Neither will land on a hobby bench, but both say something about where the technology under your desktop printer is heading.
Mastrex MX300: metal at the production end
The Mastrex MX300 is a metal laser powder-bed fusion (LPBF) system priced at $185,000. It pairs a 300 × 300 × 350 mm build volume with dual 500 W lasers, and is qualified to run aluminum, Inconel, and stainless steel. The target markets are the usual high-value ones for metal printing: aerospace, defense, and medical, where the ability to print complex, certified metal parts on demand justifies the price tag. Dual lasers are the headline — splitting a build plate between two beams is how metal machines claw back the painfully slow build speeds that have always been LPBF's weak point.
Sinterit BIANCO2: SLS on the benchtop
At the other end of the industrial spectrum, Sinterit's BIANCO2 brings selective laser sintering (SLS) to a benchtop footprint. It uses an RF CO₂ laser, a 130 × 180 × 330 mm build volume, and prints at up to 30 mm/h. Pricing starts at €47,000, with a 15% discount offered to preorder customers. Its standout feature is openness: "Full Open Parameters" exposes more than 130 adjustable settings, letting engineers tune the process and qualify their own materials rather than being locked to a vendor's profiles — a philosophy that will feel familiar to any maker who has fought a closed ecosystem.
The expansion behind the launches
The new machines arrive as the industry's infrastructure expands to meet demand. Axtra3D, a production-grade additive company founded in 2021, announced a major European expansion built around a 17,000-square-foot facility in Vicenza, Italy, to host demonstrations, validation programs, technical workshops, and manufacturing. The company reports 55% repeat-customer growth and year-over-year gains in installed systems. "The move to this new facility marks a significant milestone in Axtra3D's evolution," said CEO Gianni Zitelli. Taken together, the launches and the expansion point to an industrial market that is still investing through the hype cycle.
What LPBF and SLS actually are
Both new machines use powder-bed processes, but they are not the same technology, and the difference matters. Laser powder-bed fusion (LPBF), the process in the Mastrex MX300, spreads a thin layer of metal powder and uses a high-powered laser to melt it into solid metal, layer by layer, in an inert atmosphere. It is how production metal parts — turbine brackets, custom implants, lightweight aerospace structures — get printed today. The dual 500 W lasers on the MX300 are about throughput: two beams melting powder in parallel roughly halve the time a single laser would take to fill the same plate, attacking the slow build speeds that have always made metal printing expensive.
Selective laser sintering (SLS), the process in Sinterit's BIANCO2, also fuses powder with a laser, but the powder is polymer — usually a nylon — and it sinters rather than fully melts. SLS's superpower is that the surrounding loose powder supports the part as it prints, so you can make complex geometries, interlocking assemblies, and intricate lattices with no support structures at all. That is why product designers and engineers prize it for functional prototypes and short-run production. Historically it lived in big, expensive industrial boxes; squeezing it onto a benchtop at a five-figure price is the same kind of democratization that FDM went through a decade ago.
For a maker, neither machine is a purchase so much as a preview. The capabilities showing up at the industrial end — parallelized lasers, open and tunable process parameters, smaller and cheaper sintering — are the same ideas that, scaled down and cost-reduced, eventually reshape what sits on a hobby bench. Watching the high end is one of the better ways to guess what your next printer will be able to do.
The materials angle is where it gets concrete. Sinterit's emphasis on open, tunable parameters is a direct response to a frustration that runs from the factory floor down to the hobby bench: closed systems that only let you run the vendor's filament at the vendor's settings. Letting engineers qualify their own powders means cheaper materials and new applications, and that pressure toward openness rarely stays at the top of the market. Mastrex's qualified metals — aluminum, Inconel, stainless — tell a parallel story about which industries are pulling hardest on additive right now, with aerospace and medical still leading because the parts are valuable enough to justify the process.
For the rest of us, the takeaway is less about these specific machines than the direction they point. A market that is launching new systems, qualifying more materials, and building out facilities is a market that is still growing — and a healthy industrial base is what keeps research, components, and talent flowing down into the affordable printers most makers actually buy. The lasers, motion systems, and process know-how that show up in a $185,000 machine this year quietly become the parts and patents that make a $300 printer better a few years later. The desktop and the factory are more connected than they look.
What It Means for Makers
- Today's industrial features are tomorrow's desktop ones. Dual lasers, open parameters, and benchtop SLS all started as high-end ideas; the desktop world tends to inherit them.
- Open parameters are a win wherever they appear. Sinterit exposing 130+ settings echoes the open-firmware ethos makers already value — control beats lock-in.
- SLS is creeping down-market. A benchtop sintering machine is still five figures, but the footprint and price are moving in the direction that put FDM on every desk.
- The industry is still investing. Expansions and new systems are a healthier signal for the whole ecosystem — including the consumer end — than a market pulling back.
