Polypropylene Powder for SLS 3D Printing

Polypropylene powder, while not the most common material used for SLS 3D printing (which is nylon), is still a very popular material offered by industrial SLS 3D printer manufacturers. Polypropylene’s omnipresence in the commodity plastics market means that polypropylene is a must-have material for any manufacturer looking to offer end-use production solutions.

Polypropylene materials exhibit lightweightness, impermeability to water, chemical resistance, and ductility. With a density typically ranging between 0.895 and 0.93 g/cm3, polypropylene is one of the least dense plastics available, making it ideal for applications requiring reduced weight.

Renowned for its thermal resistance, along with hydrophobic and oleophobic properties, polypropylene finds extensive use in the food packaging sector. Through formulations with various additives, polypropylene can achieve enhanced toughness, rendering it suitable for engineering applications subjected to repetitive pressure or impact.

While the heat deflection temperature (HDT) of most polypropylene variants reaches approximately 100 °C at 0.45 MPa, which isn’t exceptionally high, it remains versatile for a diverse array of applications.
