Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a clamp for a 3D printer. Background Art

[0002] 3D printer, also known as three-dimensional printer (3DP), is a machine of cumulative manufacturing technology, that is, rapid prototyping technology. It is based on a digital model file and uses special wax materials, powdered metal or plastic and other bonded substrates to print layers of bonded substrates to create three-dimensional objects. There are various types of media that can be used for printing, from a variety of plastics to metals, ceramics and rubber materials. It is based on a digital model file. Among the metal substrates, alumina and zirconia ceramics are more commonly used. However, 3D printers often print substrates on substrates during the process, so a positioning fixture is needed to fix the substrate.

[0003] The positioning fixture usually clamps and positions substrates of the same size. Since three-dimensional objects of different sizes are often manufactured during each printing process, different substrate sizes also need to be changed. However, due to the different substrate sizes, the positioning fixture needs to be replaced. Otherwise, it is not easy to quickly position the substrate, further reducing the work efficiency of substrate printing. Utility Model Content
