How is Multi Jet Fusion different from SLS?

Selective Laser Sintering (SLS) and Multi Jet Fusion (MJF) technologies are used for different types of powder 3D printing. Unlike SLS, where the polymer is spot-fused using lasers, MJF fuses the powder and bonding agent with IR light.

For an SLS printer running at 100% capacity, it can take up to 30 hours to fuse and cool the printed product. With MJF, on the other hand, printing takes 12.5 hours, and quick cooling — 4 hours.

Products created using MJF technology have stable mechanical properties and detailed, smooth surfaces. Various materials are used for such printing, as follows:

• Polyamide HP PA 12 allows you to create durable products with complex designs, thin walls, inscriptions, and logos. This material is resistant to water, ultraviolet radiation, and chemicals, as well as being biocompatible.
• Polypropylene is the optimal material for printing prototypes and finished products: car interior elements, cases, boxes, and other items. Polypropylene products are proof against alcohols, oils, ethers, and other chemicals. They are durable and resistant to moisture.
• Thermoplastic polyurethane is suitable for creating flexible elastic products, such as shoe parts, seals, and gaskets. Products made of this material do not crack when deformed and return to their original shape. The material can withstand exposure to oils, solvents, and a number of acids.
