Meaning a laser of a specific wavelength and intensity is focused on the surface of the light-cured material, causing it to solidify sequentially from point to line and from line to surface, completing the drawing of one layer, and then moving the lift table in the vertical direction to the height of one layer, and then curing another layer. Stereolithography stands for “SLA”, which is a three-dimensional light-curing molding method. Flat glass and clear water are examples of optically transparent materials. Such materials are said to be optically transparent not translucent. Diamond, cellophane, Pyrex, and soda-lime glass are said to be popular demonstrations of transparent materials.ĭifferent materials allow most of the light shining on them to be transmitted and hardly reflected. In fact, many liquids are highly transparent due to the absence of molecular structure and defects (voids, cracks). But they may also have a combination of colors, making a brilliant spectrum of each color. Transparent materials have a clear appearance and an overall appearance of the same color. Of course, transparent materials also follow the law of refraction. In most materials, unlike translucent, electrons are not above their available energy level in the visible range, which prevents significant absorption, and certain materials will become transparent. Transparent media includes air, glass, water, and plastics. Transparent material allows light to pass through(light passes fully, not pass partially, or scattered) them.
