Pennsylvania Special Processing (PSP) is an advanced manufacturing technique used to produce high-performance parts and components. PSP involves the use of a combination of subtractive and additive manufacturing technologies to create intricate parts with tight tolerances and complex geometries. PSP can be used to create items from a variety of materials, including metals, plastics, composites, and ceramics. The two main types of PSP are direct metal laser sintering (DMS) and selective laser sintering (SLS). DMS utilizes a high-powered laser to sinter metal powders into a three-dimensional part. SLS involves the use of a laser to selectively fuse plastic, composite, or ceramic powder into a finished product. Both processes involve the use of a computer-aided design (CAD) program to control the laser and create the desired product. Pennsylvania Special Processing is ideal for producing parts with intricate geometries and tight tolerances that are difficult to achieve with traditional manufacturing techniques. PSP can also be used to produce parts with complex internal features, such as channels and cavities. The process is also cost-effective and has a shorter lead time than traditional methods.
