FDM 3D Printing Service.
Engineering thermoplastics, built to function.
Functional thermoplastic parts as a service — real engineering plastics like ABS, ASA, carbon-filled nylon, PPS-CF and ULTEM, printed robust and to spec in Los Angeles. Upload a part for a fast, engineer-confirmed quote.
Configure your FDM part below — we read STL geometry right in your browser, so nothing leaves your computer until you place the order. Pick your thermoplastic and finishing, and a named engineer sends a firm quote and lead time within 24 hours.
Thanks — an Additive Plus engineer will confirm your quote and lead time within 24 hours. A copy is on its way to your inbox.
Two ways to order.
Order online in minutes, or get an engineer on the phone first — either way the same team and the same QC standard carry your part through.
Order online
Most orders never need a call — upload, configure, send.
- 1Upload & configure your part. A standard mutual NDA is applied automatically before any file review.
- 2A named engineer confirms your quote in 24h. A free DfAM check runs in parallel — we flag anything before printing.
- 3We print, finish, QA & ship. Printed, support-removed, cleaned and inspected to spec on calibrated FDM systems — lead time confirmed with your quote.
Talk to an engineer
For tricky geometry, load-bearing parts or strict material programs — get it right the first time.
- 1Call us, or request a callback. We sign a custom NDA if your program needs one.
- 2An engineer reviews your part and sends a firm, optimized quote — with material, orientation and DfAM suggestions to de-risk the build.
- 3Approve by web link or P.O. — into production on the same QC standard.
What is FDM 3D printing — and when to choose it.
Fused Deposition Modeling (FDM) builds a part by extruding molten engineering thermoplastic filament layer by layer along a toolpath. It runs the same production plastics you’d injection-mould — ABS, ASA, PETG, carbon-filled nylon, PPS-CF and ULTEM — so parts are tough, chemically resistant and ready for real service, not just show.
Choose FDM for functional, engineering-grade thermoplastic parts: jigs, fixtures, housings, brackets, ducting and low-volume end-use components — especially larger, robust parts in real production plastics. FDM strength is anisotropic, so orientation is set for the load case. For fine detail or the smoothest cosmetic surface, SLA is the better call; for isotropic, support-free nylon, SLS.

FDM materials — 9 qualified engineering thermoplastics.
Nine production FDM thermoplastics — PLA, ABS, ASA, PETG-CF, PETG-HF, PA6-CF, PPS-CF, TPU 95A and PA12-CF — qualified with print parameters dialed in for repeatable results. High-performance grades on request: ULTEM 1010 (food-contact, PEEK-like), imported ABS-M30, UV-stable ASA and imported nylon carbon fiber. Priced per part, $50 minimum; spec sheets on request.
Hover over a material card to see its description and applications.
PLA
Rigid, easy-printing plastic for concept models, appearance checks and fit tests where cost matters most.
ABS
The workhorse engineering plastic — tough, impact-resistant and heat-tolerant for prototypes, housings and jigs.
ASA
ABS-like toughness with UV and weather resistance — for outdoor housings, covers and exterior parts.
PETG-CF
Carbon-fiber-reinforced PETG — stiff, dimensionally stable and easy to print for engineering brackets.
PETG-HF
High-flow tough PETG — impact- and chemical-resistant for enclosures and functional parts.
PA6-CF
Carbon-filled nylon — high strength, stiffness and heat resistance for structural, load-bearing parts.
PPS-CF
Carbon-filled PPS — outstanding chemical and high-temperature resistance for harsh-service parts.
TPU 95A
Flexible, rubber-like elastomer for gaskets, grips, bumpers and living hinges.
PA12-CF 25%
25% carbon-fiber nylon — lightweight, rigid and dimensionally stable for structural components.
High-performance grades on request
Need ULTEM 1010, imported ABS-M30, UV-stable ASA or nylon carbon fiber? These are quoted per project — tell us the spec and an engineer confirms availability and lead time.
Dialed-in parameters for every thermoplastic.
We tune nozzle temperature, layer height, wall count and orientation per material — so your parts come out strong, accurate and repeatable, batch after batch.
FDM tolerances & build envelopes.
Typical FDM capabilities — confirmed for your part and material. Tighter tolerances and finer layers available with engineer review; the exact build envelope is confirmed with your quote.
Receive parts made by people who obsess over the finish.
Every FDM order is printed, support-removed, cleaned, finished and inspected to spec — our team manages the print and QC, and runs specialist finishing like sanding, painting and threaded inserts through vetted partners. The same engineer sees your part from quote to QC, so what ships is exactly what you designed — finished with real care.
Every finish your FDM part can get — confirmed with your quote.
From as-printed to sanded, painted and threaded — combine finishing steps freely; every FDM order is support-removed, cleaned and inspected before it ships. Each finish is quoted with your part.
Standard finish
Every FDM order has supports removed, is cleaned up and inspected — dimensionally accurate straight off the machine.
Sanding & smoothing
Hand sanding and smoothing knocks back layer lines for a cleaner, paint-ready surface on cosmetic parts.
Painting
Primed and painted in your colors — solid, metallic or custom match after a smoothing pass.
Threaded brass inserts
Heat-set brass inserts give durable, reusable metal threads for bolted assemblies and repeated fastening.
Heat-set helicoils
Helicoil thread inserts add strong, wear-resistant threads where a part sees high torque or frequent assembly.
Precision polishing
Hand and mechanical polishing for a smooth, cosmetic surface on visible or contact parts.
Don’t see the finish you need?
Tell us the spec — a coating, insert, threading or environment-specific process that isn’t listed — and an engineer will confirm whether we run it in-house or through our vetted partner network, and quote it with your part.
Brass inserts (M2–M8) and heat-set helicoils (M2–M10) are available on most materials. Painting is done after a smoothing pass; finishes combine freely and are added to your quote.
FDM parts we shipped.
Printed, support-removed, hand-finished and inspected — managed from our L.A. shop.

High-temp, flame-retardant cabin brackets
Chemical-resistant brackets for harsh service
What our customers say
"Our ABS prototypes came back tough enough to test on the bench, not just look at. Snap-fits actually snapped and held. A named engineer flagged a wall thickness issue before printing — exactly what we needed."
"We moved our robot end-of-arm brackets to carbon-filled nylon FDM — stiff, light and far cheaper than machining. Real engineers helped pick the material and orientation, not a contact form."
"Functional thermoplastic parts with consistent tolerances, batch after batch. The ASA enclosures hold up outdoors and the fit is right every time. Our go-to for FDM now."

One applications engineer owns your part from quote to delivery — no anonymous queue.
On-time, in-spec — or we make it right.
If a part ships late or out of tolerance, we reprint it free. Free DfAM review on every quote, and a named applications engineer on every order — with a dimensional check and a named applications engineer on every order.
A manufacturing partner — not just a marketplace.
Most "instant quote" platforms route your file to an anonymous shop and hope it comes back right. We qualify the FDM materials and parameters we print on, manage finishing and QC end-to-end, and put a named engineer on every order — so quality and IP stay accountable to us.
