Use of ST LED UV curing protective box to do research on SLA Rapid Stereo lithography Prototyping Resin

SLA rapid prototyping technology was first developed by 3D System from the United States, and its working principle is as follows: data files of three-dimensional entities transmitted by a computer, after the slicing machine software, drive a scanning laser head, emit UV laser beam and scan in the liquid resin surface -min. Those points on liquid resin surface begin to polymerize to form a solid-state. After each level of the scan is completed, the table dropped the thickness of a solidified layer. A new layer of liquid resin covers the scanned surface, and then a scraper scratch accurately this new layer of resin to ensure that its thickness uniformity. If the entity has left the structure, processing software can be pre-judged and generates the necessary structure to support process. In order to prevent adhesion of the entities in the table, processing software must also generate a grid-like framework at the bottom of the entity firstly, to reduce the physical contact area with the table. SLA Rapid Prototyping Stereo lithography Resin university research is research focus of a lot of universities. We need to do a lot of tests to verify the characteristics of light-cured resin, including the requirements of light curing, curing speed, viscosity, glass transition temperature, micro-hardness after curing characteristics. Because rapid prototyping systems are valuable, a large number of tests are generally not very realistic. The use of ordinary mercury lamp can not meet the requirements of scientific research in terms of the control of exposure, quantify and the security.

GOOD launch a full-automatic LED UV Curing Machine (ST-LED), can meet the study conditions of the light-curing resins.

1．Light intensity suitable: 100Mw-8600MW/cm2 @ 320-390nm. And the light intensity can be adjusted from 10-100%.
2．Computer chip processor: built-in program modules, they can set the exposure time. With ST-LED UV light meter, it can measure the energy of the overall mJ/cm2
3．A full range of UV protection: the process of curing, ST-LED UV Ultraviolet Radiation shielding all directions, does not produce infrared light.

Under normal circumstances, light-cured resin can be solidified within the 3-10S. Equipment is very compact, and can be placed in your laboratory, only need to connect 100-240V power supply; you can start a controlled light-curing.

The use of GOOD LED UV light curing machine, can make you focus on more resin formulations, and the obtained quantitative data are more convincing.
