What is SAF technology in 3D printing?

SAF technology, or Selective Absorption Fusion, is a method of sintering polymer powders. How does it work? The process involves selectively applying an infrared absorption fluid to a layer of powder. An infrared lamp then moves over the entire surface, fusing only those areas that have been covered with the liquid. Because the heat is distributed evenly throughout the chamber, each part has identical mechanical properties. Most importantly, SAF technology eliminates the need for support structures, significantly reducing post-production time and minimizing material waste.

Key advantages of SAF printers

• Unparalleled production speed. By melting the entire layer at once, the process is much faster than with other powder technologies such as SLS.
• High repeatability and precision. The technology ensures dimensional consistency of 99.7% of the work surface with an accuracy of 100 microns.
• Material savings. No need to print support structures and the ability to recover up to 80% of unused powder make production more economical and environmentally friendly.
• Easy to use and intuitive. SAF printers are designed with ease of use in mind, reducing the time required for deployment and operator training.
• Remote production monitoring. The ability to monitor the printing process from anywhere increases flexibility and control over production.
• Industrial reliability. The use of high durability components guarantees long and trouble-free operation of the device.
  

  Applications of SAF printers in practice

  The flexibility and efficiency of SAF technology make it applicable to a wide range of industries, supporting both rapid prototyping and volume production of final parts. Where are they used?

• Automotive – vehicle interior components, housings, brackets and spare parts,
• Consumer electronics – device housings, connectors and technical components,
• Industrial equipment – guards, hinges, handles and other machine parts,
• Medicine – customized surgical instruments and medical apparatus components.
• Aerospace industry – manufacturing lightweight and durable structural parts.

SAF technology is compatible with a variety of materials, including tough PA-11 and PA-12 polyamides and flexible polypropylene (PP), allowing the print properties to be tailored to specific needs.

Comparison of SAF with other 3D printing technologies

SAF technology stands out from other 3D printing methods, especially in the context of mass production.

• SAF vs SLS : although both technologies use polymer powders, SAF uses an absorbent fluid and an IR lamp, while SLS sinter the material using a laser. This translates into higher speeds, better thermal control and greater repeatability with SAF technology.
• SAF vs. FDM/SLA: Compared to FDM and SLA technologies, SAF offers much higher productivity for large batch production, better surface quality and excellent dimensional accuracy.
