Comments Off on Can 3D print provide the necessary tolerances for shaft and hole in RC?

Yes, in theory 3D printing can achieve bilateral tolerances for shafts and holes in RC cars, but the precision depends heavily on the type of 3D printing technology used, the material, and post-processing techniques. FDM is commonly used for hobbyist 3D printing, but it typically has lower precision due to… Continue reading →

Comments Off on CNC machining for RC

CNC machining is valuable for producing certain RC car parts due to its precision, versatility, and the high-quality finishes it can achieve. Unlike molded plastic, CNC-machined parts—typically made from metal or reinforced plastic—are highly durable and capable of withstanding the demands of intense RC car racing or off-road use. One… Continue reading →
