PEEK & ULTEM 3D Printing Service
Industrial PEEK & ULTEM 3D Printing — Parts Most Shops Can't Touch.
When a part has to survive heat, chemicals, or serious load, commodity plastics don't cut it. We 3D print aerospace-grade PEEK, ULTEM 9085/1010, PPSU, and Nylon CF on industrial printers running up to 500°C — for aerospace, defense, automotive, energy, and medical R&D. Made in Rockville, MD. No minimums.

Built to Survive What Breaks Ordinary Plastic
PEEK and ULTEM aren't just "stronger PLA." They're engineering polymers used where metal is too heavy, too conductive, or too expensive — and where standard plastics melt, crack, or corrode.
Extreme Heat Resistance
PEEK holds its strength in continuous service to 260°C and survives short excursions far higher. ULTEM stays dimensionally stable past 200°C. Parts that would sag or melt in ABS keep their shape and function.
PEEK: 260°C continuousChemical & Hydrolysis Resistance
Resistant to fuels, solvents, acids, and repeated steam sterilization. PPSU is autoclave-ready; PEEK shrugs off aggressive chemistries that destroy commodity polymers — ideal for fluid handling, lab, and process equipment.
Autoclave & solvent safeStrength Without the Weight
PEEK reaches up to ~100 MPa tensile strength at a fraction of the weight of aluminum, and ULTEM 9085 carries an FAA flame-smoke-toxicity rating for flight interiors. Replace metal brackets and housings with lighter, non-corroding parts.
Metal-replacement strengthPEEK, ULTEM & Engineering Polymers
We run the materials most print farms can't process — on industrial printers with the 500°C nozzles and heated chambers they actually require.

Models & prototypingPEEK, the Skull, and the Future of Patient-Specific Implants
PEEK is one of the most exciting materials in modern reconstructive surgery. Here's what the industry has achieved, what we offer today, and where we're headed.
Why surgeons are turning to PEEK
PEEK has become a breakthrough material for cranial and maxillofacial reconstruction because its stiffness closely mirrors human bone, it's radiolucent (effectively invisible on X-ray and CT, so surgeons can image clearly around it), biocompatible, and chemically stable in the body. It's used to rebuild skull defects caused by trauma, tumor removal, and congenital deformities.
The milestone: FDA-cleared 3D-printed PEEK cranial implants
In 2024, the FDA cleared the world's first additively manufactured patient-specific PEEK cranial implant (3D Systems' VSP PEEK Cranial Implant), built on a validated workflow using implant-grade Evonik VESTAKEEP PEEK and an ISO 13485 medical process. Early cranioplasties at European and Israeli hospitals showed the approach can use up to ~85% less material than traditionally machined implants — proof that 3D-printed PEEK implants have moved from research into cleared clinical use.
What DC Additive Pros offers today
Right now, we print PEEK and ULTEM for industrial and functional applications, and we produce anatomical and surgical-planning models — patient-specific skull, bone, and defect models that surgeons, residents, and researchers use to plan complex cases, rehearse procedures, and teach. These are planning, education, and research tools — not implants — and they're available now.
Where we're headed — and who we want to hear from
We're actively exploring the patient-specific implant pathway: the implant-grade materials, validated processes, and regulatory clearances it requires. If you're a clinician, researcher, medical-device developer, or investor working on cranial, maxillofacial, or orthopedic applications and want a U.S.-based additive manufacturing partner to prototype and grow with, we'd genuinely like to talk.
