This paper address how additive manufacturing will revolutionize production and manufacturing industries, and ultimately determine the scope of what is possible to create. Due to its versatility, additive manufacturing will allow more efficient and cost-effective means of production, prototyping, and innovation. Additive manufacturing can create new parts and devices opening up new channels of change in emerging industries, such as microfluidics, medical, and dental. This evolution is equally as critical to private and public entities who desire a competitive edge over the manufacturing market, on both a national and global scale.

Digital Light Projection (DLP) technology, kinetic absorption framework, and software algorithms constituted our basis for the engineering and design aspect of a custom method of additive manufacturing capable of meeting the demands of mass production. With the barriers mentioned above in mind, this device was built to compensate in accuracy, precision (>1 micron) and speed in the resolution of all areas of X, Y, Z orientations, coupled with a large build volume. Strategic algorithms were inserted into object fabrication to achieve parts with a superior surface finish and dimensional accuracy at rapid speeds (<5 mins per 50mm). For validation, we contrasted surface finish against other additive manufacturing solutions available on the market, using the same STL file.

We compared the printed parts under a microscope and identified statistically significant differences (p>0.001) between the finished products. Our method proved superior regarding dimensional accuracy and surface finish. The technology and methods applied in this paper are a step toward key gains in manufacturing-decreased production time, more efficient use of materials and personnel, and cost efficiency. As additive manufacturing evolves, it continues to shape the way humankind thinks about production, creation, and manufacturing while simultaneously expanding research opportunities in ways never before possible.
