Update! As of 2024, there is a new Multi-PHS available — see the first overview video here: https://www.youtube.com/watch?v=K_xENBcnMSA
Join us as we embark on the intricate process of depowdering and sandblasting parts from the Lisa Pro 3D printer, specializing in powderbed SLS technology. Today’s focus is on nylon PA12, specifically nylon pa12 smooth from Sinterit.
The powder handling station plays a crucial role in the production workflow, efficiently managing messy powder by directing it into an integrated powder sieve. This sieve refreshes the powder, ensuring it’s ready for the next print. The entire system includes a post-processing sandblaster, creating a seamless and effective workflow.
Starting the process, we press a button to initiate the vacuum, securing the powder during depowdering. The cake, containing various parts, is then carefully excavated, much like an archaeological exploration in Jurassic Park.
Next, we demonstrate the depowdering step, manually brushing away excess powder from the parts. SLS, Selective Laser Sintering, or Powder bed fusion, allows the creation of functional parts without the need for support structures.
Exploring the Lisa Pro’s capabilities, we discuss its nitrogen gas chamber, allowing for a broader range of materials. Additionally, we provide insights into other models like the Lisa X, a galvo-based system with remarkable speed, and the upcoming Nils 480 for continuous production.
With most parts depowdered, we transition to the sandblasting phase, using two nozzles for different part sizes. The sandblasting process enhances the surface finish, although for finer details and prototyping, the shown method proves sufficient.
Examining the final products, we highlight the robustness of solid nylon 12 parts. Variations in printing angles are discussed, teasing a deeper exploration in an upcoming video on slicing and program usage for production or prototyping.
