SnowPod: A Compact Desktop SLM Machine
3D Print Magazine introduces SnowPod as a compact desktop SLM system planned for a Kickstarter launch. Its coverage discusses enclosed powder handling, removable support structures and the software workflow intended for studios and other small workspaces.
SnowX, a newcomer to the 3D printing industry, plans to launch a desktop SLM system, the SnowPod, through Kickstarter in the fourth quarter. The startup has integrated the SLM process into a desktop system measuring 360 by 360 by 600 mm, smaller than many FDM printers. The build chamber for printing metal parts measures 80 by 80 by 100 mm.
The Chinese startup has released the first details of SnowPod ahead of its Kickstarter campaign. SnowX is building a community on social media before the machine launches. It plans to bring a desktop metal 3D printer to design studios, laboratories, offices and production environments. SnowPod can print 316L stainless steel.
Fully enclosed powder feed system
Within its compact dimensions, the startup incorporates a 40-micron laser spot. Layer thickness can be varied from 30 to 60 microns, while the Z-axis positions with 3-micron precision. According to SnowPod’s developers, the 40-micron laser spot not only produces fine details in the workpiece but also reduces the machine’s thermal load, allowing it to remain compact. The 80 by 80 by 100 mm build volume is suitable for dental applications, jewelry, art, prototypes and specialized industrial tools. Several small parts can also be combined in a single batch. To support operator safety, the printer uses sealed powder cartridges, enclosed filters and powder recovery. According to SnowX, the idea is not to teach people to handle an industrial powder process better, but to enable the machine to manage that process for them.
A proprietary support structure that breaks away easily
One of SnowPod’s distinctive features is a support structure designed for easy removal. It is based on origami structures. Its geometry and connection points keep it stable during printing while allowing it to break away easily in the intended direction afterward. The manufacturer compares removal to opening a zipper. SnowX has also developed its own slicing software, which is supplied with SnowPod. Operation is designed so that a print job can be started with one click. Slicing and calculation of the laser toolpath take place automatically.
AI monitors the build
The machine operates under controlled gas, temperature and humidity conditions. It monitors these conditions itself and makes adjustments when needed. The oxygen level in the build chamber is reported to be no more than 2.5 ppm. The build chamber door can only be opened once specified safety requirements have been met. SnowX supplies NitroPod, a compact nitrogen generator, to produce nitrogen. It extracts high-purity nitrogen from ambient air and releases the oxygen.
A high-resolution camera and AI algorithms monitor the printing process layer by layer. When deviations are detected, such as the workpiece lifting due to the recoater, the user is alerted to the weak point. More than 90% of unused powder can be recycled, depending on the geometry of the workpiece. The first material supported by SnowPod is 316L, with other materials under development.
SnowX’s developments over the coming months can be followed on its official social media accounts. Pricing for early Kickstarter backers will also be announced there.
