Electronic enclosures and mechanical parts in 3D printing

/Electronic enclosures and mechanical parts in 3D printing

Design and production of electronic enclosures and mechanical parts in 3D printing.

Made of Nylon PA12 with HP Multi Jet Fusion printing process.

There are several aesthetic and construction options available:

– natural raw finish

– blackening finish by impregnation

– liquid coated finish with any color tone based on RAL or NCS references.

– possibility of integrating silkscreen printing, digital printing, labels, sheet glass, CNC milling details, die-cut gaskets, etc.

With the Multi Jet Fusion technology is possible to create very robust, high-density parts in Nylon PA12 with extreme precision in the details.

For this reason, today is the ideal solution for prototyping and for the mass production of functional objects in plastic material.

What distinguishes us from a typical 3D printing service? In MCS we have a clear vision of the finished product, we know that, for an electronic product there are very high expectations from a technical, functional and aesthetic point of view.

Therefore, In MCS we have developed our skills in order to obtain parts with high technical, functional and aesthetic characteristics.

In MCS we don’t limit ourselves to just printing a file provided by the customer, but we are able to design and create customized and made-to-measure objects.

  • Customized electronics enclosure made with 3D printing processes, processing of PVC milled from sheet and with a digitally printed polyester overlay. An innovative solution that combines precision, functionality and design. Our implementation processes:
    • Finalising the customer’s project.
    • Production of the front panel, machined from PVC sheet, with inserts and studs for fixing the electronic boards.
    • Embossed polyester membrane, with graphics made by digital printing process.
    • 3D printed shell, in rough finish and blackened by impregnation (basic aesthetic treatment, economical, alternative to painting, but extremely functional)
    Tips & Tricks To facilitate use and installation, we have inserted magnets into the 3D shell. This solution allows the tool to be easily attached to the metal housing of the machine, improving practicality and handling. This type of solution is ideal for batches from 25-50-100 pieces/lot. Why?
    • Because with machining entirely from solid material, some shaped details would be difficult to achieve.
    • Because machining entirely from solid would lead to significant material waste due to chip removal in CNC milling.
    • Because the alternative of mould production would require significant investment in equipment, with recommended batches starting from 500 pieces per lot. Despite a lower unit cost, it’s essential to consider the amortization of non-recurring costs, taking into account production estimates and the continuity of reordering over time.
