Services & technologies
3D printing services and technologies, from prototype to low-volume production
Different parts call for different 3D printing technologies. VEYSEN offers SLM, MJF, SLS, SLA, DLP and FDM. Tell us what your part needs to do, and we’ll recommend the material and process.
What we do
Prototyping
No tooling. Production starts once your file is confirmed, which suits appearance checks, fit checks and functional tests.
Low-volume production
When the quantity doesn’t justify a mold, 3D printing produces usable parts directly.
Material and process advice
Describe the application and working conditions, and we’ll recommend a material and technology from experience.
Post-processing on request
Heat treatment for metal parts, anodizing for 6061, CNC finishing of critical surfaces, thread tapping, polishing, sandblasting and painting.
Six printing technologies
Metal
SLM — Selective Laser Melting
A laser melts metal powder layer by layer to form dense metal parts. It suits functional parts that need strength and shapes that are hard to machine.
Materials: 316L, 17-4PH, AlSi10Mg, 6061, 18Ni300, Ti6Al4V
Nylon
MJF — Multi Jet Fusion
HP’s powder-bed process fuses nylon powder with a fusing agent and heat, with no support structures. It suits functional parts and low-volume production.
Materials: PA12, PA12+GF
Nylon
SLS — Selective Laser Sintering
A laser sinters nylon powder layer by layer, also without supports. It suits functional parts with complex shapes.
Materials: PA12, PA12+GF
Resin
SLA — Stereolithography
A UV laser cures liquid resin layer by layer, giving a fine surface. It suits appearance models, transparent parts and large parts.
Materials: ABS-like resin, transparent / translucent resin, high-temperature resin
Resin
DLP — Digital Light Processing
A projector cures a full layer of resin at once, with layers as thin as 0.016 mm. It suits small parts with fine detail.
Material: red wax resin
Engineering plastics
FDM — Fused Deposition Modeling
Heated thermoplastic filament is extruded and stacked layer by layer. It costs less and suits jigs and general functional parts.
Materials: ABS, PC, PETG
Tolerances
Dimensional tolerances depend on the printing technology and the part geometry. Tell us about critical dimensions when you request a quote, and we’ll assess the accuracy we can reach and whether CNC finishing is needed.
Post-processing and surface finish
Every part gets the necessary post-processing steps.
Standard finishing removes supports and support marks.
Some layer lines will still be visible.
For a finer surface, add polishing, sandblasting or painting.
