The technology
What is LPBF metal 3D printing — and when to choose it.
Laser Powder Bed Fusion (LPBF) — also sold as DMLS or SLM — fully melts a bed of fine metal powder, layer by layer, with a fiber laser under an inert argon or nitrogen atmosphere. Because every layer is fully melted and fused, parts reach over 99.5% density with near-wrought mechanical properties — far stronger than sintered or binder-jet metal.
Choose LPBF when you need functional metal parts with complex geometry: conformal cooling channels, internal passages, topology-optimized brackets and lattices that can't be machined or cast. Layers are 20–60 µm; as-built surfaces are Ra 6–12 µm, so we CNC-machine or polish sealing faces and bores after printing, and add heat treatment or HIP for fatigue-critical aerospace and medical parts.
Engineer's takeFor very large near-net shapes, look at DED / WAAM; for high-volume small parts at lower density, binder jetting. Need a polymer or nylon part instead? Ask an engineer — we recommend the process that meets your spec and budget, even if it isn't LPBF.

★ ATO Lab · atomize + print
Can’t buy the alloy you need? We’ll atomize it — and print it.
Beyond our seven stocked alloys, our in-house ATO atomization line turns your feedstock or specification into qualified LPBF powder — custom blends, biocompatible and refractory alloys, atomized to the particle-size distribution your build needs. You get a spherical, lot-traceable powder with a Certificate of Analysis, typically in 3–4 weeks — then we run it on this same LPBF line and ship you finished, inspected parts, not just powder. One partner from a composition you can’t source to a part in your hand.
Custom & proprietary alloysBring a composition or feedstock — we atomize the blend you can’t source.
Biocompatible & refractoryMedical-grade and high-temperature alloys atomized to spec.
Atomized, then printedControlled PSD, sphericity and chemistry with a COA — then printed to spec on our LPBF line.
★ Finishing & QC
Receive metal parts made by people who obsess over density and tolerance.
Every LPBF order is printed, stress-relieved, cut from the build plate, heat-treated, finished and inspected to spec. We manufacture across our own Los Angeles shop and a vetted partner network — routing each build to the right line for your alloy, tolerance and certification — and QC every part before it ships. The same engineer follows your part from quote to final inspection, so what ships is exactly what you designed.

Frequently asked questions
Don't see your question? Our team responds personally to any inquiry in under 24 hours.
Talk to us →How much does LPBF metal 3D printing cost?
Pricing is instant — upload your STL and the calculator returns a live price as you pick the alloy and finishing, from a $50 minimum. LPBF parts are priced by part volume and alloy: aluminium (AlSi10Mg) is the most economical, titanium and Inconel the most premium. Heavy, fully solid parts cost more in dense metal, so engineers hollow or lattice where the design allows, and bulk quantities earn automatic discounts.
How fast can I get my LPBF metal parts?
Most LPBF orders ship in about 5–8 business days, including stress relief and support removal; parts that need heat treatment, HIP or CNC finishing of critical features take longer, and rush is available on a priority queue. A free engineer DfAM check runs in parallel and a named applications engineer confirms your quote within 24 hours.
How accurate are LPBF metal parts?
LPBF / DMLS holds a typical tolerance of ±0.1–0.2 mm (about ±0.2% over larger dimensions) with 20–60 µm layers. As-built surface roughness is Ra 6–12 µm — for sealing faces, bores and mating features we CNC-machine or polish to your spec after printing, reaching ±0.025 mm where the drawing requires it. Tighter tolerances are confirmed by an engineer before the build.
How strong and dense are LPBF metal parts?
LPBF fully melts the metal powder layer by layer, so parts reach over 99.5% density with mechanical properties at or near wrought material — far stronger than sintered or binder-jet metal. Final strength depends on the alloy and heat treatment: maraging steel ages past 1,900 MPa, Ti-6Al-4V exceeds 1,100 MPa UTS, and Inconel 718 holds strength at high temperature. For fatigue-critical aerospace and medical parts we add hot isostatic pressing (HIP).
Which metal alloys do you offer for LPBF?
7 production LPBF alloys: 316L stainless steel (corrosion-resistant, marine and medical), 17-4PH stainless steel (precipitation-hardening, high strength), 18Ni300 maraging / mould steel (tooling and conformal-cooling inserts), AlSi10Mg aluminium (lightweight brackets and heat exchangers), Ti-6Al-4V titanium Grade 23 (aerospace and biocompatible medical), Inconel 718 nickel superalloy (high-temperature) and CuCrZn copper alloy (high thermal and electrical conductivity). Custom and biocompatible alloys are atomized in-house by ATO Lab. We accept STL, STEP, OBJ, 3MF and IGES — no CAD file? We can redraw from a sketch, photo or sample.
What post-processing and finishing is available for metal parts?
Every LPBF order includes stress relief, removal from the build plate (wire-EDM or bandsaw) and support removal. Optional, priced per part: solution / age heat treatment, hot isostatic pressing (HIP), CNC machining of critical features, precision polishing (Ra 3.2), passivation for stainless, electrophoresis coating, helicoil and brass thread inserts, and thread tapping. An engineer specifies the right finishing route for your alloy and application — and if you need a finish that isn't listed, just ask.
What is LPBF 3D printing, and how is it different from DMLS, SLM, DED or binder jetting?
Laser Powder Bed Fusion (LPBF) — also marketed as DMLS or SLM — fully melts a bed of fine metal powder layer by layer with a fiber laser under an inert argon or nitrogen atmosphere, producing fully dense functional metal parts with complex geometry and internal channels. Choose LPBF for high-accuracy, high-density metal parts. For very large near-net shapes consider DED or WAAM; for high-volume small parts at lower density, binder jetting. Not sure? Ask an engineer — we recommend the process that meets your spec and budget.
How big can LPBF metal parts be?
Build envelope is up to about 400 × 400 × 400 mm depending on the machine and alloy, with most parts running in our 250 × 250 × 325 mm class systems. Parts larger than the build plate are split and joined with engineered, qualified joints, or routed to our DED / large-format metal lines.
How do supports, orientation and trapped powder affect my design?
LPBF needs supports on down-facing surfaces and steep overhangs (below ~45°) to anchor the part and conduct heat — these leave witness marks we grind or machine off. Hollow or channelled parts need drain/escape holes (≥ 2–3 mm) so unmelted powder can be removed; trapped powder adds weight and can't be certified. Our free DfAM check flags overhangs, thin walls, trapped volumes and distortion risk before we print — upload your file and we'll advise on orientation.
Can you print parts with internal channels and lattices?
Yes — internal cooling channels, conformal waterlines, manifolds and lattice structures are exactly where LPBF beats machining and casting. We design self-supporting channel cross-sections (teardrop or diamond) where possible, add powder-escape holes, and verify clearance with the DfAM check. Tell us the flow, pressure or mass-reduction target and an engineer optimizes the geometry.
Are your metal parts certified for aerospace and medical?
We work to AS9100, ISO 13485 and NADCAP-aligned practices and are ITAR-aware. Tell your engineer the standard you work to and we'll confirm what we can support before the build.
Can you atomize a custom or biocompatible alloy I can't buy?
Yes — our in-house ATO atomization service turns your composition or feedstock into qualified, spherical LPBF powder with a controlled particle-size distribution and a Certificate of Analysis, typically in 3–4 weeks. This covers custom blends, biocompatible and refractory alloys you can't source off the shelf. Send us the spec and we'll quote the atomization run and the print together.
What is the minimum order, which files do you accept, and where do you ship from?
Minimum order is $50. We accept STL, STEP, OBJ, 3MF and IGES files — no file? We can redraw from a sketch, photo or sample. Print services and warehouse are in Los Angeles; shipping is calculated per order and shown at checkout. Upload your part for an instant price.
Is my design protected?
Mutual NDA is standard before file review — no exceptions, no extra charge, typical turnaround under 1 hour. Your files are read locally in your browser for quoting and never leave your computer until you order; every project is handled by a named engineer and managed end-to-end from our Los Angeles shop.
