The MPCNC (Mostly Printed CNC) is an innovative DIY CNC machine designed by V1 Engineering that stands out for its accessibility, affordability, and versatility. This machine is primarily constructed using 3D-printed parts combined with commonly available hardware like conduit or stainless steel tubing, making it an excellent choice for makers, hobbyists, and small workshops looking to venture into CNC machining without breaking the bank.
One of the most impressive aspects of the MPCNC is its scalable design. The machine can be built in virtually any size, limited only by the rigidity of your materials and workspace. The mostly-printed construction means that anyone with access to a 3D printer can fabricate the necessary parts, while the remainder of the build relies on inexpensive materials like EMT conduit, bearings, and standard hardware store components.
The assembly process is well-documented with comprehensive instructions, though it does require patience and attention to detail. The modular design allows for easy modifications and upgrades, and the active community provides excellent support for troubleshooting and customization.
The MPCNC performs admirably for its price point. It's capable of cutting wood, foam, plastics, and soft metals like aluminum when properly configured. While it won't match the precision and speed of industrial CNC machines, it delivers surprisingly good results for hobby applications, prototyping, and light production work.
The machine can also be adapted for various tasks beyond milling—including laser engraving, plasma cutting, 3D printing, and even drag knife operations. This versatility makes it an excellent all-in-one fabrication platform for creative projects.
