BigRep is returning to private ownership roughly two years after its stock-market listing, while opening worldwide orders for the ALTRA 670, a large-format industrial printer built for engineering polymers.
The two announcements put a new machine launch alongside a change in how the Berlin-based manufacturer funds and organizes its business. BigRep reports revenue growth of approximately 45% over the past twelve months, even as management acknowledges that the broader additive manufacturing market did not expand as quickly as expected when the company went public.
Three existing investors take ownership
Shareholders have approved a simplified corporate structure, leaving BigRep owned by Koehler Invest GmbH, DeKrassny GmbH and Hage Holding GmbH. All three are family-owned businesses and longstanding backers of the manufacturer.
CEO Thomas Janics-Jakomini said the listing had rested on expectations of rapid additive manufacturing market growth that ultimately proved too optimistic.
“Returning to private ownership allows us to refocus our resources on product development and growth.”

BigRep attributes its recent revenue increase to technology initiatives, portfolio additions and operational changes introduced since Janics-Jakomini became CEO in November 2024. The reported growth provides context for the ownership change, but it is not a measure of profitability.
All BigRep printers are now manufactured at the company’s own facility in Austria. BigRep says this arrangement gives it full control over its supply chain and more flexibility in production and delivery.
ALTRA 670 expands a high-temperature platform
The ALTRA 670 builds on the ALTRA 280, retaining servo motors, a ball screw drive and an industrial control system while increasing the available build space. BigRep says first-series machines are already in production.
Its central specifications are:
- Build dimensions: 1200 x 700 x 800 mm, expressed as length, width and height.
- Build chamber and print bed temperatures: up to 140°C each.
- Extrusion system: two water-cooled DSX extruders, reaching up to 450°C.
- Nozzle options: 0.6 or 1.0 mm diameter.
- Filament diameter: 1.75 mm.
- Machine weight: approximately 1,870 kg.
The official product page lists the same build dimensions using X 700, Y 1200 and Z 800 mm. That is a difference in axis labeling rather than a different build envelope.
BigRep positions the machine for large engineering-polymer parts, functional prototypes, jigs, fixtures and production aids. Its temperature capabilities support high-grade polycarbonate and other high-performance polymers, although material compatibility does not guarantee a ready-made printing profile.
The product page specifically identifies ABS, ASA and PC as recommended materials with BLADE slicing profiles. Its broader compatibility list includes reinforced nylons, PEKK, PPS and PPSU, among other polymers.
Automation addresses long print jobs
Beyond its size and temperature ratings, the ALTRA 670 includes automated calibration through topology measurement and compensation, adaptive mesh bed leveling and an HD camera for remote monitoring.
Its Relay Mode switches to the second extruder when filament runs out. A sealed dry-storage chamber holds four filament spools, while BigRep’s open material system allows compatible filament from outside suppliers.
The launch also follows other portfolio changes. BigRep introduced the ONE.5X in April as a more automated update to the ONE.5 with broader material support. It is working with Massive Dimension on pellet extrusion and Endless Industries on continuous fiber reinforcement.
Industrial customers shape the sales expansion
BigRep says its platforms use Western-manufactured control systems and comply with cybersecurity requirements it describes as part of the EU’s new Machinery Directive.
The manufacturer is emphasizing secure, traceable supply chains for defense, aerospace and other sensitive applications while strengthening its offices in Singapore and the United States.
Recent reseller additions include Alfex CNC in Australia, 3DXTECH in the United States and Phillips Corporation in Malaysia. BigRep reports more than 1,000 large-scale printers operating worldwide, with customers including Bridgestone, Kawasaki, Ford, Airbus and Daimler, as well as educational and research institutions.
