DyeMansion Smooths 3D Prints With EIC Accelerator and EIB Money

Parts that come out of a powder-bed 3D printer are rough, matt and porous, which keeps them out of most products people touch, wash or seal. DyeMansion, a machine builder in Planegg near Munich, sells the equipment that turns those raw parts into finished goods: blasting cabinets that clean and surface them, dyeing machines that colour them, and the Powerfuse S, a chamber in which solvent vapor melts the outer skin of a plastic part so that it hardens again smooth, sealed and glossy.

The European Innovation Council chose that machine in its first Green Deal round. The Commission's list of projects selected at the 19 May 2020 cut-off names DyeMansion GmbH as the only company in Powerfuse S 4 AM, with grant-only funding. According to CORDIS, the EIC Accelerator pilot project ran from 1 December 2020 to 31 May 2023 with an EU contribution of €1,498,404 towards a total cost of €2,140,577.14. Six years later DyeMansion sells three vapor smoothing machines and is still independent, though its own accounts show it has never made a profit.

What DyeMansion Does Now

DyeMansion is operating and still buying and partnering. In October 2025 it acquired ASM, a Munich start-up founded in 2021, and with it the VX1, a compact vapor smoothing machine that more than 50 customers already used; the price was not disclosed, according to 3D Printing Industry and 3DPrinting.com. The second adds that the two companies had sold the VX1 together since October 2024. In July 2026 the Polish printer maker Sinterit began selling the VX1 and DyeMansion's DM60 dyeing system alongside its own printers, according to 3D Printing Industry and TCT Magazine. Both report that a compact Powershot blasting system is due at Formnext 2026.

The register shows the same picture of a company that is alive. North Data lists patent publications in March, April, June and September 2026, an annual report for 2024 published in February 2026, and share capital raised to €88,996 by May 2025. No insolvency or liquidation notice appears. The 2024 accounts themselves could not be read for this article.

The Technology: Melting the Surface, Not Sanding It

The cheapest way to finish a 3D-printed plastic part is to blast it with fine media, which DyeMansion also sells. Blasting removes loose powder and evens out the surface, but leaves it matt and still slightly open. Vapor smoothing goes further: the solvent condenses on the part, dissolves a thin outer layer, and the polymer hardens again once the solvent is removed. CORDIS describes the result as smooth, water-repellent and glossy, wipeable for food and medical uses and airtight enough to carry fluids or gases.

When DyeMansion launched the Powerfuse S at Formnext in November 2019, it pitched the process, which it calls VaporFuse Surfacing, as the "first chemical smoothing solution" that was clean and industry-ready, according to TCT Magazine. The machine took PA11, PA12, TPU and, in beta, ULTEM parts from several printing technologies, with cycles of 40 to 80 minutes in a 129-litre chamber, and recovered its solvent in a closed loop, according to the specifications published by 3D Printing Industry. DyeMansion was not alone: the British company AMT had UK patents granted in 2020 on its own PostPro3D chemical vapor smoothing machines, according to 3D Printing Industry. DyeMansion's 2023 management report also names "new competitors" that could push down prices.

What the EIC Project Promised, and What the Record Shows

The project set out to make the Powerfuse S a "large-scale, industry 4.0-ready, sustainable system", to develop the process for more industrial polymers and to lay the "legal, sales and operational foundations" for the market, according to CORDIS. The final periodic report says five external pilot customers ran more than 750 cycles, two further prototypes were built, one of them a Powerfuse S PP for polypropylene, and that Industry 4.0 features, augmented-reality-assisted maintenance and an as-a-service business model were developed before series production and a worldwide supply chain were set up. The project ended on its scheduled date.

Most of that can be checked outside CORDIS.

5. AR-assisted maintenanceReport onlyNamed in the CORDIS report; no separate product announcement found.

The scope was narrow, because the core product already existed before the award, and DyeMansion did what it said it would do with it. Four of the five goals have public evidence outside CORDIS; the fifth is a feature the company reported on CORDIS, for which no separate product announcement could be found. The polypropylene machine took the process to a plastic the original Powerfuse S did not cover, validated with material suppliers including HP, BASF and EOS, according to VoxelMatters.

What DyeMansion Has Achieved Since the Award

The money came before and after the grant. A €4.5 million Series A in September 2018, reported as $5 million, came from UVC Partners, btov and AM Ventures, according to Munich Startup and Tech.eu. In August 2020, three months after the EIC cut-off, Nordic Alpha Partners led a Series B of €12 million, reported in dollars as $14 million, joined by existing investors UVC Partners, btov, KGAL and AM Ventures, according to Munich Startup and Tech.eu.

In February 2022 the EIC Fund put in €4 million and the European Investment Bank lent €11 million in venture debt backed by the European Guarantee Fund, according to the EIB and DyeMansion's own release, which credits "the successful market launch" of the Powerfuse S for the EIC Fund's decision. The company appears in the official EIC Fund portfolio with a company page that gives no amount or date. Neither release states the instrument; the 2022 accounts record an extended Series B of €4.2 million signed in December 2021 and paid in the first quarter of 2022. In December 2023 a further extension of about €5.5 million was signed, with €3.5 million paid in early 2024 and the rest tied to milestones expected in 2025, according to the 2023 accounts.

Customers are named often but counted inconsistently. DyeMansion claimed more than 400 customers in 2018 and more than 600 in 2020, including BMW, Daimler and Under Armour, according to Munich Startup. Additive Manufacturing reported 425 in early 2024, and in October 2025 the company gave more than 500 customers and over 1,300 installed machines in 50 countries, according to 3D Printing Industry. The counts may use different definitions; none can be checked against an independent source.

The Money

The filed accounts, published in the Unternehmensregister and available for 2022 and 2023, show a growing business that is not close to paying for itself. Revenue rose 29.0% to €9.9 million in 2022 and 15.4% to €11.4 million in 2023, against a forecast of 25 to 30%, which the management blamed on customers holding back investment. EBITDA was minus €5.0 million in 2023 and the net loss €5,781,894.67, after €5,649,422.92 in 2022 and €5,679,099.63 in 2021. Export took 49.1% of 2023 sales.

Equity fell from €7.34 million at the end of 2021 to €0.90 million at the end of 2023, and cash from €8.41 million to €1.52 million in the year after the EIB loan was drawn. Bank debt stood at €11.40 million. Both years carry an auditor's note from Rödl & Partner of a "material uncertainty" about the company's ability to continue, because it depends on new money from investors and on reaching its sales plan. The management report for 2023 expected low double-digit growth a year and EBITDA break-even within three years. Whether 2024 met that could not be verified: the 2024 accounts are listed by North Data but were not accessible for this article.

Why Europe Should Care

Additive manufacturing is one of the areas where the Commission wants Europe to hold its edge: its advanced manufacturing policy page says it supports the sector and proposes revising taxonomy rules "to recognise the greening potential of additive manufacturing", while warning that access to finance "particularly for scale-ups" remains a critical problem. The machine builders' association CECIMO argued in April 2026 that Europe struggles "in scaling from innovation to industrial deployment", in a policy paper on the sector. The CORDIS report calls post-processing "the key to turning rapid prototyping and 3D printing into large volume AM", and the EIB's investment officer said in DyeMansion's 2022 release that post-processing "should be one of the winners following the Covid crisis".

DyeMansion is a small case of that problem. The EU paid for the product, an EU fund took a stake and an EU bank lent it most of its debt. The company built the machines and found buyers, but at €11.4 million of sales it is still a niche supplier that needs fresh capital to keep growing.
