3-D Printing

3-D printing, also called rapid prototyping, creates three-dimensional objects by laying down successive layers of material. In a world where more and more schools have 3-D printers, it is no surprise that some are now 3-D printing dragsters.

While the ABS and other materials used might not be traditional, they do have a more predictable and consistent mass than a body blank made of wood. As with CNC milling, the dragster must first be designed in a CAD program and be digitally connected to a 3-D printer to print out the design.

However, when using 3-D printing, extra precautions should be taken because normal body blanks have predrilled cartridge holes to ensure proper depth for a safe launch.
