How we run it

Metal 3D printing

DMLS is rarely the cheapest way to make a simple part. It dominates when the part geometry is impossible — or nearly impossible — any other way.

02 · What only DMLS enables

Geometries that break CNC.

Topology-optimized brackets

Organic weight-reduced shapes from generative software (nTopology, Fusion 360). Aerospace brackets routinely 40–60% lighter at equal stiffness.

Conformal cooling channels

Curved cooling channels follow the part geometry rather than straight drilled holes. Cuts injection mold cycle time 15–40% in tool inserts.

Lattice and gyroid structures

Internal lattices reduce weight, absorb impact, or act as heat exchangers. Impossible to machine; trivial to print.

Integrated assembly reduction

Multi-part assemblies become one-piece DMLS parts. Eliminates fasteners, seals, tolerance stack-up. Example: GE Catalyst turboprop reduced 855 parts to 12.

Functionally graded density

Solid walls transitioning to internal lattice in a single print. Structural stiffness where needed, weight savings elsewhere.

Hybrid DMLS + CNC workflow

Print near-net shape in DMLS, then CNC-machine critical mating surfaces. Best of both worlds: complex geometry + precision interfaces.

DMLS is rarely the cheapest way to make a simple part. It dominates when the part geometry is impossible — or nearly impossible — any other way.

FAQ

Metal parts with geometry CNC can't reach — questions

What metals can PifyC 3D print via DMLS?

Titanium Ti-6Al-4V (Grade 23, medical-grade ELI available), aluminum AlSi10Mg, stainless steel 316L and 17-4 PH, Inconel 625 and 718 (superalloys), maraging tool steel MS1 (1.2709). Custom alloys may be available with 4–6 week lead time depending on powder availability.

What is the build volume for DMLS?

Our DMLS system has a build envelope of 250 × 250 × 300 mm. Larger parts must be split and welded or fastened. For parts up to that size, we can pack multiple parts into one build to reduce per-part cost.

What tolerances can DMLS hold as-printed?

As-printed tolerances are ±0.1 mm or ±0.2% of the feature dimension, whichever is greater. Surface finish is Ra 6–10 µm as-printed (rough). For precision mating features and smoother finishes, we recommend hybrid workflow: DMLS print + CNC finish of critical surfaces. This achieves ±0.01 mm tolerances on bearing seats, threaded holes, and alignment features.

Do you offer HIP and heat treatment for metal 3D printed parts?

Yes. Hot Isostatic Pressing (HIP) for porosity reduction, solution annealing, age hardening, and stress relief. HIP is standard for flight-critical aerospace parts, taking as-printed density from 99.8% to 99.99%+ and closing internal voids. We work with vetted certified HIP partners.

Is DMLS suitable for production, or just prototypes?

DMLS is production-capable. Our aerospace customers use it for flight-qualified brackets, medical customers for implantable titanium components (with post-processing), and motorsport teams for optimized brake calipers and suspension components. For runs above ~200 parts, compare total cost against CNC or investment casting.

What is unique about topology-optimized DMLS parts?

DMLS enables geometries CNC cannot reach: organic weight-optimized shapes (typically 40–60% lighter than machined equivalent), internal lattice structures, conformal cooling channels in mold inserts, integrated features that would otherwise require assembly. Combined with generative design software, topology-optimized DMLS parts are transforming aerospace brackets and motorsport components.
