3D printing, or additive manufacturing, has over the years become a reliable manufacturing method used in various industrial areas.
There are numerous benefits.
Through the design freedoms it offers, 3D printing releases the designer's creativity and accelerates the time-to-market of your product by producing realistic and functional prototypes. It is now opening up to mass production while reducing lead times 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 which will surely have a profound effect on current manufacturing methods in the coming years. Pending the ability to obtain 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.
Although additive manufacturing has many benefits, there remains the major issue of the diverse and varied post-processing steps which are 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 manufacture or traditional processes, plastic parts need specific treatments in order to meet customers' expectations. Unpolished surfaces must be reworked using different post-processing solutions to obtain the desired finish, whether 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.
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.
CLEANING & DECONTAMINATION + INCREASE OF SURFACE AREA + ACTIVATION =
ADHESION OF METALLIC DEPOSIT
ADHESION OF ORGANIC DEPOSIT
The combination of these three functions results in sufficient levels of adhesion between polymers + metallic layers + organic finishes, such as paints and varnishes.
Metalizz has mastered all polymer surface treatments and has acquired a vast amount of rare experience in the area of metallic and organic deposits.
Pour la phase d’activation, nous utilisons des technologies connues comme les décharges corona For the activation phase, we use known technologies such as corona discharges at the polymer surface, but above all 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.
Regarding the increase in the specific surface area, we have mastered automatic sandblasting solutions using various tried, tested and validated media which can be mixed depending on the characteristics of the substrates to be treated.
Lastly, we are developing our own chemical metallization solutions in order to meet the specific characteristics of the polymers and manufacturing techniques which enables us to obtain the best possible results in terms of adhesion, and therefore performance over time, for your applications.
This mix of unique know-how is at the heart of the solutions we offer and we know how to adapt them to your projects through specific studies.
The chemical metallization processes developed by Metalizz make it possible to:
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.
Once plastic parts have been treated with the Utility Silver Layer process, they can be processed in electrolytic metallization baths which allow anything from a few microns to several millimetres of metal to be deposited to meet numerous aesthetic and functional requirements.
Although the aesthetic properties that metallization brings to plastic are well-known and undeniable (gloss, lustre, mirror effect, satin, brushed effect, etc.), its other advantages are less obvious: simulating the weight and cold touch of metal, even with a very fine deposit. This sensory aspect is highly sought-after, particularly so in perfumery applications where the density of the product is synonymous with perceived quality.
As to the functional characteristics, the metal deposit enhances the mechanical properties of the parts and also gives them technical properties such as EMI shielding.
Lastly, metallization of polymer parts is a substitute solution for 3D metal printingwhich overcomes its constraints and costs.
By adopting metallization, you will become a leader in your field in producing plastic parts with a metal finish at the speed of additive manufacture while taking advantage of the lower costs of polymers.
All 3D-printed parts can be coated in metal, whatever their design, geometry or complexity just like any part injected or manufactured in zamac.
So, widen your perspective and convert your production to obtain finished ready-to-use products and not just prototypes!
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 validating a collection, a customer presentation, an exhibition 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!
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:
So, how can you get an idea of what is possible faced with this plethora of materials and technologies?
Whether FFF, SLA, DLP, SLS or proprietary processes such as MJF, MJP, CLIP and other acronyms, we are always on the lookout and regularly test the "best sellers" of additive manufacturing to check their compatibility with our processes.
From cleaning through smoothing and metallization to varnishing, we scrutinise, examine and study the materials from every angle and submit them to numerous qualification tests: moisture regain, wettability, aptitude for metallization, chemical resistance to solvents, mechanical or physico-chemical treatments, etc. The list is long!
