SLA print-3D print

2018-12-25


3D printingThe design process of 3D printing:

Firstly use software to build a model, and then split the 3D model to a layer-by-layer cross-section, ie, slicing, so as to guide the printer to print layer by layer.

The standard file format between design software and printers is the STL file. A STL file uses a triangular face to approximate the surface of a simulated object. The smaller the triangular face, the higher the generated surface resolution. PLY is a scanner that generates a 3D file by scanning, and the generated VRML or WRL file is often used as an input file for full-color printing.


SLA Techonology

Focusing on the surface of the photocurable material with a laser of a specific wavelength and intensity, from point to line, from line to surface solidification, complete a level of drawing operation, then the lifting table moves the height of a layer in the vertical direction, and then solidifies Another level. This layer superposition constitutes a three-dimensional entity.


The advantages of SLA Rapid Prototyping

■ It has the longest development time, the most mature technology and the most widely used.
■ The forming speed is faster and the system works stably.
■ Highly flexible.
■ High precision, can achieve micron level, such as 0.025mm.
■ The surface quality is good and smooth: suitable for fine parts.
