High performance 3D printers are now an integral part of the most advanced creative and production processes, not only in the field of prototyping, but also in the fields of design, engineering, design and architecture, art, clothing, jewelry, scientific and medical research.
There are many 3D printing technologies, which include:
Digital Light Processing (DLP), in which a tank of liquid polymers is gradually exposed to the light of a special DLP projector in safelight conditions, allowing the object to solidify. The excess polymer is removed and discarded at the end of the solidification process.
Stereolithography (SLA) or selective fusion, a concept similar to Selective Laser Sintering (SLS) and Direct Metal Laser Sintering (DMSL), which sinter only the material necessary with a special laser. Metal polymers, resins, thermoplastics, sand and glass are used. Conceptually, SLA keeps the excess product in its granular state, using it as a support and eliminating it at the end of the process.
Laminated Object Manufacturing (LOM), a lamination system that uses various techniques and provides thin layers of materials, which are subsequently joined to give life to the final three-dimensional shape.
3D Inkjet Print (3DIP), real inkjet 3D printing that generates already coloured three-dimensional objects by means of the solidification of coloured granular polymers. It allows you to obtain high details and coloured shapes, but with small dimensions, long production times and high inking costs.
Fused Deposition Modeling (FDM) or Extrusion, the most widely used, where a nozzle deposits the molten polymer, stratifying it on a support structure. Flushing materials of varying thicknesses and colours are generally used (PLA, ABS, edible materials and many others).
Gel Dispensing Printing (GDP), which is a one-of-a-kind process. A special UV curing gel allows you to build objects much faster than any other system on the market, saving a significant amount of material thanks to the elimination, except in rare cases, of the usual supports of 3D shapes.
“GDP” TECHNOLOGY IN DETAIL
The Gel Dispensing Printing (GDP) technology represents true innovation. The process is completely different from previous 3D printing systems (extrusion, incandescent or sintering) and uses a technology similar to that used in Fused Deposition Modeling (FDM) systems. When used, Dimengel®, which is sensitive to UV light, polymerises almost instantaneously using special UV lights.
This allows you to print large objects much more quickly than any other 3D printing system. The comparison is simple: it prints at a speed of 35 cm/hour, with regard to height, instead of 7 cm/hour average offered by current 3D printers.
The printing time obviously depends on the size and complexity of the form. It takes about 5 hours to print a full size sculpture of a standing human being (Adam), but it is also possible to print another subject (for example, Eva) at the same time.
Overall, GDP technology allows you to create extremely large objects very quickly.
