Prototal was one of the first prototype manufacturers in Europe to use a 3D printer. Already in the 1980s we were printing parts for constructors, consultants and procurement departments throughout Scandinavia. The technology is constantly advancing at breakneck speed, and the possibilities offered by 3D printing are increasing accordingly. Nowadays, for instance, 3D-printing is also used in series production. When you choose us as supplier, you get more than just a prototype. You get our experience, know-how and the reassurance that we understand your future manufacturing process. We make sure your prototype construction is fully customised and ready to take the step to full production.
Stereolithography – or SLA 3D printing – is used mainly where surface finish, a high level of detail and dimensional accuracy are most important. SLA is also excellent for design models or master patterns for casting. You can customise the prototype by choosing several different materials to obtain the correct transparency, flexibility or rigidity. In the case of design models, the part is polished and lacquered to make it as similar to the end product as possible. We add different surface textures, graphics, print and colours. SLA is one of a number of alternatives in rapid prototyping / additive manufacturing / 3D printing.
Selective laser sintering, or SLS, is used where the functionality and durability of the prototype are important. By choosing different materials, you can get parts with extreme flexibility, rigidity and resistance to aging. SLS is the best option if you need your product to be made from a durable material. SLS is a free-form fabrication method where we create the prototype directly from your CAD data without first producing a die. By means of various types of post-processing, design models can be produced, for instance. In this case the part is polished and lacquered to make it as similar to the end product as possible. We add different surface textures, graphics, print and colours. SLS is one of a number of alternatives in rapid prototyping / additive manufacturing / 3D printing.
Multi Jet Fusion, or just MJF, is the new type of SLS fabrication.
With its amazing speed and resolution, the printer sets a new standard for what is possible in 3D printing. The machine is ideal for prototypes as well as series production in quantities that have not previously been associated with additive manufacturing.
The machine also offers a finer level of detail and better resolution than corresponding methods using thermoplastics. The properties of the parts exceed those obtained via selective laser sintering, SLS.
The printed models can be e.g. infiltrated, lacquered, dyed or polished to achieve the desired finish. MJF is one of a number of alternatives in rapid prototyping / additive manufacturing / 3D printing.
Fused Deposition Modelling, extrusion. This method offers high levels of dimensional and geometrical accuracy. An application with good thermoplastic properties which often means that FDM technology is the preferred choice.
PolyJet is a 3D printing method that uses liquid acrylic polymers as base material.
A high level of detail and excellent surface finish are just some of the advantages of this method.
