Polypropylene (PP) is a semi-crystalline thermoplastic widely used in the industry due to its low cost, for example, a third of the plastics used in a car are polypropylene. However, the prototyping of parts made in PP is not as common as its high-volume manufacturing. 3D printing with polypropylene is ideal for quick prototypes and the validation of designs that will be subsequently injected.
Printing with PP using FDM technology requires a bed temperature of around 60 °C, and an extrusion temperature of 220 °C.
Compared with 3D printing with Nylon, printing with PP offers the advantage of more stability in humid environments as it has minimal water absorption. It has a highly elongated breaking point and flexibility (good shock resistance). It has excellent chemical resistance.
Send us your 3D file ready to print.
If you do not have the file, send us the item and we will create the CAD file.
If you need a design from scratch, our designers will gladly prepare a quote for you.
We will create the process file adapted to the technology and materials that will be used to produce your item.
We prepare and condition the printer to guarantee optimum quality.
This step is key when meeting your requirements, and it is one that we are highly specialised in.
The removal of the printing support structures, heat treatments, and surface finishes (blasting, polishing, tooling) are some of the most common post processes.
Polypropylene strengthened with fibreglass has a very high tensile modulus making it extremely useful for industry as a whole. Likewise, the versatility of 3D printing with PP when it comes to quick prototypes for design validations of injection parts is also a commonly used benefit.
Large items can be printed up to 600x325x500 mm.
Large items can be printed up to 600 x 325 x 500 mm.
One of the best qualities of the 3NTR-A2 is that almost any FDM developed filament can be used.
In addition to this service with PP, we also offer it in the following materials: Take a look and decide the one best suited to your needs.
we use a 3D laser scanner to obtain three dimensional models of items wich we do not have the drawings.
We design conformal cooling channels for plastic and aluminium injection inserts. With our inserts the cycle time is improved in addition to the quality of the injected item.
