The most common materials for printing parts with soft plastics are TPU (Thermoplastic Polyurethane) and TPE (Thermoplastic Elastomer). TPU is a lineal chain elastomer with good chemical, wear, and abrasion resistance. The presence of hard and soft segments in its chemical composition mean that it can be combined in different proportions to adapt the hardness of the TPU to the mechanical demands of the specific application. TPE is a very elastic polyurethane based material, but additives are added to it in order to increase its capacity to warp and to recover its shape without breaking. It has a matt finish, unlike the shiny surface of TPU.
3D printers for soft plastics such as TPU and TEP require a special extrusion head to resolve any material retraction issues and to ensure that the material flow is constant.
– 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 zero, 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.
The flexibility and elasticity of TPU and TPE, together with their chemical resistance and large vibration and shock absorption capacities make them the ideal materials for the printing of deformable objects in industrial environments or for specific items.
3NTR is one of the leading professional plastic printer manufacturers. Its large AS model has a liquid cooled extruder that allows engineered plastics to be printed.
Large items can be printed up to 600x325x500 mm.
One of the best qualities of the 3NTR-A2 is that almost any FDM developed filament can be used.
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.
