Description

Technical Field

[0001] The utility model belongs to the technical field of 3D printing fixtures, in particular to a 3D printing fixture with adjustable angle. Background Art

[0002] 3D printing is a technology that uses digital model files as the basis and uses bondable materials such as powdered metal or plastic to construct objects by printing layer by layer.

[0003] In the existing metal 3D printing process, metal parts need to be clamped to ensure printing accuracy. However, the commonly used clamps cannot stably clamp special-shaped parts. There is a gap between the clamp and the metal part, which causes the clamp to not clamp tightly and affects printing. At the same time, the clamp only clamps two sides of the metal part and cannot stably clamp large metal parts. The metal part shakes, affecting printing accuracy. Utility Model Content
