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 ph12 smooth from Citra.
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 emptied, resembling an archaeological exploration in Jurassic Park.
Next, we demonstrate the depowdering step, manually brushing away excess powder from the parts. Notably, the Lisa Pro enables the creation of functional parts without the need for support structures, showcasing its versatility and efficiency.
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 Mills 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.
