Description

Technical Field

[0001] The invention relates to the technical field of 3D printers, and in particular to a portable carbon fiber 3D printer and a method for using the same. Background Art

[0002] A 3D printer, also known as a three-dimensional printer (3DP), is a device that uses cumulative manufacturing technology (i.e. rapid prototyping technology). It is based on a digital model file and uses adhesive materials such as powdered metal, special wax or plastic to print layers of adhesive materials to create three-dimensional objects. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will print the product layer by layer according to the pre-edited program.

[0003] The traditional 3D printer structures mainly include gantry structures and box-type four-support structures. These two types of printers have complex structures, large volumes, high production costs, and are difficult to operate. The most common 3D printer is a gantry-type three-coordinate 3D printer, which has been widely used for its structural stability and long-term durability. However, because the gantry-type 3D printer uses three guide rail slider mechanisms to perform three-coordinate positioning, it occupies a large space, is heavy, has a slow printing speed, and requires more power and energy, which cannot achieve better energy-saving effects and meet human requirements for space. The box-type structure is also more popular on the market, but it has a more complex structure, is not easy to assemble, is troublesome to maintain, and requires very high precision parts, and the cost of the entire model is high.
