‌We recently started an ASTRAL 3D YouTube channel (check it out here) and posted our first video, an unboxing of the Elegoo Mars Pro 3D Resin Printer.

The Elegoo Mars Pro offers:

Higher Precision and Excellent Performance: Z axis utilises linear guideway structure, which achieves steadier motion and greatly enhanced moving accuracy to reduce the layer lines on the 3D printed model and make the surface much smoother. The set screws of the build plate are now upgraded to larger anti-slip hexagon socket screws, which have a more stable leveling result. CNC turning CD pattern on the build plate provides a much stronger adherence, especially when printing large 3D models.

No Irritative Odor Experience: Mars Pro comes with a silicone rubber seal that can be put on the cover to prevent the resin odor from leaking. Built-in activated carbon can absorb and filter the resin odor before they are ventilated throughout the cooling fan, which gives you a fresh and safe user experience.

Light and Convenient: Remodeled resin vat made of aluminum alloy is light yet sturdy. The USB port is relocated to the front for your convenience. Mars Pro uses a new user interface with a dark theme and simple design.

Quality Prints and Consistent Success: Matrix light source consists of 28 50Watt UV LED lights that have uniform light emission, ensuring superior printing results, a more accurate printing size, and saves your time by 25% in layer exposure time. Mars Pro is the first resin-based 3D printer to use the sliced file of .ctb format, which reduces the file size by an average of 90% compared to .cbddlp format and significantly increases the printing success rate when printing bigger models.
