3D printing: what are the benefits?

3D printing, or additive manufacturing, has over the years become a reliable manufacturing method used in various industrial areas.

There are numerous benefits.

Thanks to the design freedoms it offers, 3D printing frees the creativity of designers. It also accelerates the marketing of your products by producing realistic and functional prototypes. It is now open to mass production, while reducing delays and limiting manufacturing costs.

From prototype to large production runs, additive manufacturing has become essential through various technologies such as FFF, stereolithography, selective laser sintering or silicon printing, Polyjet, DLP and Multi Jet Fusion. Changing the format, geometry and design has never been so easy..

And let's not forget the arrival of metal 3D printing qui bouleversera sûrement dans les années à venir les méthodes de fabrication actuelles.

Until we can get high quality 3D printed metal parts at a reasonable cost: Metalizz offers solutions for giving metallic lustre to 3D printed plastic parts via the chemical metallization process Utility Silver Layer.



Do you know about 3D post-processing?

If additive manufacturing has many advantages, there is still a downside. The various and varied stages of post-processing, often complex, time-consuming and costly.

Post-processing and finishing 3D-printed parts still currently represents a major proportion of the manual work needed for their manufacture. Depending on the application, these steps can represent between 30% and 60% of the total cost.

With its innovative processes, Metalizz shortens these processes.

Whether from additive manufacturing or traditional processes, plastic parts require specific treatments to meet customer expectations. The raw surface states must be reworked through different post-treatment solutions to obtain the desired finish (aesthetic or functional).

Cleaning and decontamination, surface activation and smoothing of polymer parts are all processes which must be mastered in order to successfully enhance 3D-printed parts with high-quality decoration and finishes, such as metallization.


Surface activation and adhesion

Making metal adhere to a plastic is a difficult step and one which in certain cases is impossible. The physico-chemical characteristics of polymer surfaces are not, in most cases, compatible with metallization processes without an activation operation on the surface being carried out beforehand to allow the metal deposit to adhere at atomic level. Surface activation requires systematic cleaning beforehand in order to remove any contaminants which could adversely affect the subsequent activation step.

In most cases, activation consists of grafting chemical elements onto the polymer surface (ligands) which subsequently generate covalent links with the metallic layers. Micro topological modifications of the surface also increase the specific surface areas of the polymers and increase the cohesion forces between the substrate and the metal deposit. The specific surface area is of major importance for phenomena which make use of surface adsorption and absorption.






The combination of these three functions results in sufficient levels of adherence. It is between polymers, metal layers, organic finishes, like paints and varnishes that everything is at stake.


Why call on Metalizz?

Metalizz has mastered all polymer surface treatments and has acquired a vast amount of rare experience in the area of metallic and organic deposits.

For the activation phase, we use technologies known as landfills corona on the surface of polymers. Most importantly, we are able to implement advanced and innovative processes using low pressure plasma with a multitude of precursor gases via automated sequences.

What's special about us? We know how to adapt these gases to the chemical composition of the polymers.


Concerning the increase of the specific area. We master automated sanding solutions with various experienced and validated media. They can be mixed according to the characteristics of the substrates to be treated.

Lastly, we are developing our own chemical metallization solutions to meet the specificities of polymers and manufacturing techniques. This allows us to obtain the best possible result in terms of adhesion, thus performance over time, for your applications.

This unique mix of know-how is at the heart of the solutions we offer. We know how to adapt them to your projects through specific studies.

Chemical metallization: what are the results?

The chemical metallization processes developed by Metalizz make it possible to:

  • initiate an electrolytic deposit on plastic materials from 3D printing (resins, powders, fibres, etc.) Utility Silver Layer
  • chemically deposit metallized layers for aesthetic reasons - LOOK LIKE CHROMIUM®
  • produce electrical conductivity on plastic
  • carry out EMI shielding and ensure electromagnetic compatibility of plastic parts – Fara D Layer.


It is by studying the requirements of those involved in the 3D printing sector that we have decided to develop chemical metallization solutions suited to their requirements.

Une fois vos pièces plastiques traitées avec le procédé Utility Silver Layer. Vous pourrez les passer dans les bains de métallisation électrolytique. Ils permettent de déposer de quelques microns à plusieurs millimètres d’épaisseur de métal. Ils répondront ainsi à de nombreux besoins à la fois esthétiques et fonctionnels.

Although the aesthetic properties que la métallisation confère aux pièces plastiques sont connues et indéniables (brillance, éclat, effet miroir, rendu satiné, brossé…). Son autre atout l’est moins : simulating the weight and cold touch of metal, même avec un dépôt très fin. Cet aspect sensoriel très recherché. Notamment pour des applications de parfumerie où la densité des produits est synonyme de qualité perçue.

As to the caractéristiques fonctionnelles. Le dépôt de métal renforce les propriétés mécaniques des pièces et leur donne également des propriétés techniques tel que le EMI shielding.

Lastly, la métallisation de pièces polymères est également une solution de substitution de l’impression 3D métal. Elle vous permet de vous affranchir de ses contraintes et de ses coûts. 

By adopting metallization, you will be a pioneer in your field of activity by making plastic parts in metal finish. With the speed of additive manufacturing, you will benefit from the lowest polymer costs.


Everything you print in 3D can be coated with metal, regardless of the design, geometry or complexity of the piece. Like any injected or made of zamak.

So, widen your perspective and convert your production to obtain finished ready-to-use products and not just prototypes!


Do you want colours?

Or to validate an idea, carry out a feasibility study or carry out consumer tests? Prototypes and mock-ups are essential in the lifecycle of a product.

With ultra-realistic models, you can accelerate customers' decision-making processes and steal a march over your competitors..

To turn designs into reality and convert raw parts into finished products, a number of finishing steps are needed in order to obtain the rendering required: smoothing, decoration, protection.

The choice of a finish or an embellishment certainly expresses the desire to stand out but above all creates a real emotional impact both by appearance and feel..

Combine polymer 3D printing and our finishing processes such as LOOK LIKE CHROMIUM® and enhance your parts.

Whether for a collection validation, a customer presentation, a show or an event, or the manufacture of limited series. The possibilities are endless.

Translucent gloss varnish, matt, opaque, coloured, metal, satin or soft touch effect - you choose!



3D Materials

Almost every week, the additive manufacturing field comes up with a new material with sometimes totally new properties.

The range of plastics currently available is already vast:

  • ABS, PLA (biodegradable), PET (100% recyclable), Polycarbonate, Polypropylene (PP), PEEK, ULTEM or flexible, composite, hybrid and soluble materials for FFF printing,
  • liquid photosensitive resins are used with SLA, DLP or even Polyjet technologies,
  • plastic powders such as polyamides (nylon), the most well-known being PA12 and PA11 (from castor oil) widely present in SLS additive manufacture.

So, how can you get an idea of what is possible faced with this plethora of materials and technologies?

Whether it’s FDM, SLA, DLP, SLS and proprietary processes such as MJF, MJP, CLIP and other acronyms, we stay on standby. In addition, we regularly test additive manufacturing best-sellers to verify their compatibility with our processes.

From cleaning through smoothing and metallization to varnishing, we scrutinize, examine and study materials from every angle. Finally, we submit them to numerous qualification tests: moisture recovery, wettability, metallization skills, chemical resistance to solvents, mechanical or physico-chemical treatments, etc. The list is long!
