What are the process parameters of stereolithography?

What are the process parameters of stereolithography?

Stereolithography (SL) is one of the most popular RP process used for rapid tooling applications. There are several process parameters contributing to the strength of an SL product. The contribution of three parameters; namely, layer thickness, post curing time and orientation are most significant.

What are the process parameters of SLA system that influence the part quality?

The part characteristics of SL product are essential for the intended functional applications. The parameters are layer thickness, orientation, Post curing, hatch spacing and over cure.

What is unique about the stereolithography process?

Advantages. One of the advantages of stereolithography is its speed; functional parts can be manufactured within a day. The length of time it takes to produce a single part depends upon the complexity of the design and the size. Printing time can last anywhere from hours to more than a day.

Is 3D printing stereolithography?

Stereolithography (SLA) 3D printing is the most common resin 3D printing process that has become vastly popular for its ability to produce high-accuracy, isotropic, and watertight prototypes and end-use parts in a range of advanced materials with fine features and smooth surface finish.

What materials can be used with stereolithography?

What are the material options for Stereolithography?

  • Polypropylene: A flexible, durable resin that mimics a stiff polypropylene.
  • Polypropylene/ABS blend: Strong, white plastic similar to a CNC machined polypropylene/ABS blend.
