Post-processing

Downstream processes for hygienic components.

Post-processing for industrial applications

After SLS printing, a component is not yet a finished product. Only targeted post-processing turns it into a functional component that can be used directly in your application.

We process your components exactly to drawing and requirements, with a focus on dimensional accuracy, function and clean, reproducible execution.

Clean components as the foundation

No air pockets, no foreign particles, no powder residue. A uniform, clean surface is the prerequisite for reliable function and safe processes.

Especially for components with strict hygiene requirements, cleanliness plays a central role throughout the entire manufacturing process. It starts with controlled powder preparation and ends with shipping.

A key element is complete depowdering. Internal channels and complex geometries are also reliably cleaned, so that no residues remain in the component.

This is particularly crucial for functional components, pneumatic structures or sensitive applications.

Ready to use

You receive a fully finished component that can be integrated into your application without any further rework.

This reduces your internal effort, avoids interface problems and ensures safe and fast commissioning.

Do you manufacture your components yourself?

No problem. We also offer all our post-processing methods as a stand-alone service, so you get exactly the finishing your components need.

Finishing

Information

Thread cutting (internal & external)
Metric, fine, imperial and special threads possible.
Internal threads from approx. M2 to M25 as well as various pipe and UN threads available.
Printed threads are possible directly from approx. 6 mm; re-cutting is often recommended for functional reliability.
LMD thread inserts
Stainless steel thread inserts for load-bearing connections and compressed air and vacuum applications.
With integrated sealing surface for O-rings, suitable e.g. for Piab vacuum nozzles.
The required installation geometry (CAD template) must be taken into account in the design.
KerbKonus thread inserts (Ensat)
Self-tapping stainless steel thread inserts (e.g. Ensat-S, -SB, -SBD).
Standard sizes from M2 to M12 available, special types on request.
No pre-tapping required, as they are self-tapping.
Optimum hole diameters and installation conditions must be taken into account.
Reaming holes (fits)
Production of precise fitting holes (H7).
Recommendation: design holes approx. 0.1–0.2 mm below nominal size.
Reamers available in the range 1–26 mm (H7, partly in 0.1 mm increments).
Dyeing
Components can be dyed in many standard colours, e.g.:
black, brown, yellow, green, red, blue, orange, violet and many more.
Custom colours can also be realised on request.
Chemical smoothing (vapour smoothing)
Improved surface quality through chemical smoothing.
Reduces roughness, closes pores and increases the tightness of components.
Ideal for applications with high demands on feel, appearance or media contact (e.g. air, liquids).
Also improves cleanability and reduces dirt adhesion.
Flocking
Application of a velvety surface by electrostatic flocking.
Reduces friction and noise and improves the feel.
Ideal for applications with sensitive surfaces or for noise damping.
Painting
Application of paint coatings for visual enhancement or functional improvement. ESD coatings are also possible.
Available in various colours and surface finishes (matt, gloss).
Additional protection against dirt and environmental influences.
Functional coatings
Non-stick and sliding coating, temperature-resistant functional coating, elastic non-stick coating (soft-touch / textured surface), smooth easy-to-clean coating, corundum coatings
Grinding (mechanical finishing)
Manual or machine processing of surfaces to improve dimensional accuracy and function.
Suitable for sealing surfaces, contact surfaces or moving components.
Reduces roughness and improves the fit, e.g. for O-rings or guides.
Assembly of components
Complete assembly of assemblies including bought-in parts possible.
Integration of e.g. suction cups, air connections, thread inserts as well as milled and turned parts.
On request including standard quick-change systems and functional testing.

Assemblies & Assembly

Precise manufacturing. Precise finishing.
Precise assembly.

M9 A5547

Do you need not just individual components, but a complete, ready-assembled unit?

We manufacture according to your drawings and design data and, on request, take care of the complete assembly. We combine additively manufactured components with standard components, bought-in parts and mechanical and electronic components.

This way you receive your assembly to your specifications – fully assembled and ready for integration into your application.

As always: The highest quality is our standard.

Unpacking, cleaning & shot peening

Careful unpacking. Thorough cleaning.
Surface densification.

For components with internal channels, complex geometries or high hygiene requirements in particular, thorough cleaning is crucial for subsequent function and process reliability.

So that you can rely on your components, LMD uses a well-thought-out post-processing concept. Our APS unpacking station for the EOS P3 systems, developed together with Siebtechnik, enables controlled powder management. By strictly separating materials and production batches, we minimise the risk of foreign material and contamination.

Your components then undergo two coordinated blasting passes. We clean internal channels and hard-to-reach areas with special tools and check that the channels are free of loose powder residue.

Particularly in hygiene-critical applications or with downstream valves, remaining powder residue can cause significant problems. To treat even complex internal geometries in a targeted way, we develop our own cleaning and post-processing solutions – including for the chemical smoothing of internal surfaces.

Your advantage: you receive carefully cleaned, inspected components prepared for your application. Unpacking, cleaning, blasting and shot peening are already included in the part price.
