German Service Bureau Malping Adds Industrial FGF PEEK 3D Printing

A small company in Neuhausen auf den Fildern, Germany, is quietly building a niche that most desktop-focused 3D printing services have not bothered to enter. Malping now offers fused granulate fabrication (FGF) PEEK as a production service for industrial customers, using an AIM3D ExAM 510 system that prints directly from pellet feedstock rather than spooled filament.

The difference matters more than it sounds. Filament-grade PEEK is expensive to produce because the extrusion step that turns pellets into spool adds cost and introduces variability. Buying PEEK in granulate form and feeding it straight into the printer removes that step entirely. Malping says the approach cuts large-part costs by 40 to 60 percent compared to conventional filament-based FDM, and the ExAM 510's 510 x 510 x 410 mm build volume lets the company print parts in one piece that would otherwise need to be split and bonded.

Who actually needs this

PEEK is the high-performance polymer that shows up in aerospace brackets, medical implants, and oil-and-gas seals. It holds its mechanical properties at 250 degrees Celsius and resists most chemicals, which makes it useful where nylon or PETG would deform. The catch is that PEEK demands high extrusion temperatures, heated chambers, and careful drying. Most desktop printers cannot handle it reliably, and even the ones that can rarely justify the cost for small batches.

Malping founder Bastian Gaedike frames the business around function, not material: "Our customers do not buy a material, they buy a function." The company consults on material selection before committing to a print, which means a customer who would be fine with polyamide does not get upsold into PEEK. That approach is unusual in a market where many service bureaus lead with their most expensive option.

In-house finishing closes the tolerance gap

FGF on its own does not hit the tolerances that CNC machining can reach. Malping pairs the ExAM 510 with in-house CNC post-processing, bringing functional surface tolerances down to plus or minus 0.05 mm. That combination is rare. Most FGF operations hand off finishing to a separate subcontractor, which adds time and risk. Keeping it in-house means the company can quote a complete part from CAD file to delivery without splitting the workflow across vendors.

Material range beyond PEEK

Alongside PEEK and carbon-fiber-reinforced PEEK, Malping runs PPS-GF20 (a polyphenylene sulfide filled with glass fiber) and PEKK, another high-temperature polyketone. It also operates a Vision Miner 22 Idex filament system for smaller, higher-detail work, so a customer can order a hand-sized PEKK prototype on one machine and a meter-scale PEEK bracket on another in the same job.

What this means for the market

Large-format high-temperature polymer printing has been an industrial process for years, but most of the equipment has been priced beyond the reach of small and medium manufacturers. Malping's model sidesteps the capital expense by offering it as a service, which opens the technology to firms that would never buy an ExAM 510 outright. The company is also exploring ESD-safe and other specialty granulates, which could draw business from electronics and medical firms that have specific material certification requirements.

The 3D printing service market is crowded at the low end, where dozens of print farms compete on PLA and PETG turnaround times. Malping is aiming at the opposite end of the spectrum, where the barriers to entry are higher and the margins are better. Whether the company can sustain that position depends on execution, but the FGF PEEK niche is one that very few competitors are currently serving.
