SLA 3D printing technology is the result of technological innovations in prototyping and production businesses. Printing Technology has developed rapidly owing to the needs and demands of designers, engineers, and more such stakeholders to incorporate technological advancements in their respective work fields.
The SLA 3D printing process includes the production of 3D models, cosmetic prototypes, and more complex parts using computer-controlled moving UV laser beams. It is managed through pre-programmed CAD software. The reason for the popularity of this printing method in the hardware industry is its ability to create 3D prototypes or models in as fast as 24hours. The parts are constructed using a wide variety of materials that provide various features, resolutions, and surface quality.
The models created through SLA 3D printing are used in various industries, including toys, automotive, house applications, medical devices, etc. It is a technological marvel, that enables various industries to create physical working models from digital models incorporating a wide variety of materials. You can find some good manufacturers of SLA 3D printing in China for your next project.
Let’s discuss the materials used for SLA 3D printing:
ABS-like Resin
The ABS-like resin material is used for its high strength and good dimensional stability. Owing to its properties like impact resistance, ease to give secondary finishing, and quality appearance it is commonly used for automotive parts, consumer packaging, electrical housing, toys, etc.
Heat deflection: 46 degrees Celcius
Minimum wall thickness: 0.6 MM
Minimum hole diameter: 1.0 MM
Hardness: 79 Shore D
Shrinkage rate: 1%-3%
Impact strength: 23-29J/CM
Clear/Translucent Resin
This material is used to create translucent models due to its ability to provide near-colorless transparency. The translucent material offers low moisture absorption quality. It is the perfect choice for general applications, including flow-visualization models, light pipes, and lenses.
