04 — Additive

Industrial 3D printing —
from prototype to series part.

Additive manufacturing with HP Multi Jet Fusion, FDM and SLA for prototypes, functional parts and series parts. We print and finish in-house and deliver ready to install. As part of our fixture systems or as a stand-alone service.

· Processes

Three processes,
one standard.

Selected by part, material and quantity. All machines in-house.

01 · Powder bed

HP Multi Jet Fusion

Production-grade functional parts in PA12: high strength, fine detail, economical from quantity 1 to small series. Our workhorse for load-bearing parts.

02 · Fused deposition

FDM

Large build volumes and engineering thermoplastics — for robust fixture components, gauges and prototypes with short lead times.

03 · Stereolithography

SLA

Highest surface quality and detail fidelity — for visible parts, fine geometries and precise-fit prototypes in product development.

· Applications

What our customers use
3D printing for.

From one-off to series — always with function, installation and unit cost in mind.

05 · Development

Functional prototypes

Fitting prototypes in a few days — assembled with clamping elements and threaded inserts and testable under real conditions.

06 · Part consolidation

One-piece air distributor

Previously welded from individual parts, now printed in one piece — flow-optimised, no weld seams, with integrated mounting.

07 · Fixture building

Vacuum fixtures

Contoured support with inserted sealing cord — parts are held flat by suction, free of distortion.

08 · Hybrid manufacturing

Part supports, machined

3D-printed base body, functional surfaces then CNC-machined — lightweight, dimensionally accurate and directly marked.

09 · Mechanical engineering · Lubrication

Oil distribution components

Internal channels printed directly, grease nipples screwed in — ready to install in one piece.

3D-gedruckte Lackierabdeckungen
10 · Surface technology

Paint masks

Contoured masks for painting — instead of taping each part by hand. Reusable and fitted in seconds.

Drill jigs

Contoured to the part, with inserted drill bushes and quick-release clamps — lightweight, clearly marked and usable directly on the structure.

12 · Finishing

Painted parts

Printed and painted — a robust, coloured surface in signal colour that no longer looks 3D-printed.

· In-house post-processing

Printed is only half finished —
what matters is the post-processing.

Complete post-processing of our 3D-printed parts in-house — printed, finished and ready to install from a single source.

The same part — three stages of post-processing

Nine finishes, one point of contact.

Dyeing

In a dip process under pressure and heat, the dye penetrates up to 200 µm into the open pores and bonds with the base material — permanent, abrasion-resistant, not a paint.

Smoothing

Chemical vapour smoothing: pores close, small irregularities even out. The result is a smooth, practically pore-free surface.

Painting

Protected, refined surface in any RAL colour — matching your product, machine or corporate identity.

Flocking

Wear-resistant flock coating: protects delicate parts, improves sliding properties and prevents marks on high-value components.

05

Rubber coating

Elastic coating for grippers and fixtures: distributes surface pressure, dampens impacts, holds without marks — ideal for holding and clamping functions.

Infiltration

Sealed surface for higher stability, compressive strength and water-tightness — also protects against contamination.

Electroplating

Galvanic metal coating (copper, nickel) for functional or decorative surfaces on plastic parts.

EMC & ESD coating

Conductive coatings against electromagnetic interference and unwanted electrostatic discharge — for electronics environments.

Powder coating

Robust, impact-resistant coating in RAL colours — for parts under mechanical stress in daily production.

Plus: mechanical post-processing.

Fitting threaded inserts

Metal threaded inserts for load-bearing, repeatedly detachable screw connections in plastic parts.

CNC finishing

Fits, functional surfaces and bores are machined to tolerance.

Structures & textures

Custom surface structures for friction, haptics or heat dissipation — printed directly.

Assembly of add-on parts

Clamping elements, inserts and standard parts are fitted — the part arrives ready to install.

· Frequently asked questions

Questions about 3D printing.

Can threads be printed directly?+

Yes. Threads can be printed directly. For highly loaded or frequently loosened screw connections we alternatively fit metal threaded inserts — we choose the right solution for the requirement.

Which processes and materials do you use?+

HP Multi Jet Fusion (PA12), FDM for large or technical parts, and SLA for fine, smooth surfaces. We recommend the process based on function, quantity and surface.

How quickly will I receive my part?+

Prototypes usually within a few days. For post-processing such as dyeing, smoothing or painting, allow a few extra days depending on the process.

Do you also finish parts not printed by prexels?+

No. We offer post-processing for our own 3D prints — that way we guarantee material, process and result from a single source.

Is 3D printing suitable for series parts?+

Yes. With HP MJF we produce reproducible series — such as housings, brackets or interior components — including post-processing and quality inspection.

What tolerances can be achieved in 3D printing?+

With HP MJF typically ±0.3 % of nominal length, at least ±0.3 mm. On request we machine fits and functional surfaces — milling tolerances then apply.

How large can a part be?+

The HP MJF build volume is approx. 380 × 284 × 380 mm. Larger parts are split in the design and joined, or produced by FDM.

What data do you need for a quotation?+

A STEP or STL model is enough. For post-processing or tolerances, a drawing or a short note on the functional surfaces helps.

Is there a minimum order quantity?+

No. We produce from quantity 1 — from a single prototype to recurring series.

3D printing or milling — which makes sense for my part?+

Complex geometries, undercuts and small quantities favour 3D printing. Simple shapes, tight tolerances or metal favour milling. Often the combination is best — we recommend the right process.

Got a part,
process undecided?

Send us a sketch, photo, STEP file or requirements specification — we recommend the process and post-processing and get back to you with a first solution approach.
