3D Printing Mold Material Processing

3D Printing Mold Material Processing

3D-printed materials are regarded as inherently defective due to macroscopic structural inhomogeneities and defects that are typically associated with the selected additive manufacturing process, often manifesting as non-nominal features in the designed build geometry. These include surface texture characteristics such as roughness and waviness, as well as residual powder—such as channels, pores, and cavities—and thread machining. In particular, surface waviness and finish quality are critical considerations. Consequently, more advanced post-processing steps, such as CNC machining, may be required when using processes like AFS-D friction stir additive manufacturing or AW-DED arc-wire directed-energy deposition 3D printing.

3D Printing and Traditional Machining

3D Printing and Traditional Machining

3D printing, also known as additive manufacturing (AM), emerged in the 1990s. Unlike traditional subtractive manufacturing methods, 3D printing is a technology that uses computer software to create three-dimensional models through design and scanning, and then builds up objects layer by layer by depositing discrete materials such as powders or filaments.

Introduction to Heat-Shrink Tool Handles

Introduction to Heat-Shrink Tool Handles

Heat-shrink tool holders are an important tool in modern machining. They offer a novel solution to the challenge of material connection. The unique principle behind their operation is to use a heat-shrink sleeve to reduce the length of the tool holder, followed by the application of a heat-activated adhesive patch to lock the shortened length in place, thereby achieving the desired connection.
