Stereolithography is a 3D printing method using photopolymerization to convert liquid plastic into solid 3D objects. Basically, liquid photosensitive resins are cured by an UV light source layer by layer. The addition of all these layers leads to the formation of the 3D object.
Digital Light Processing (DLP)
Digital Light Processing is a similar process to stereolithography, based on the idea of using photopolymers. However, the major difference is the light source which is applied to the entire bottom of the vat filled with photopolymer resin in a single pass, generally leading to faster printing speeds. At the same time, DLP produces highly accurate parts with excellent resolution. Also, the vat is more shallow which results in even less wasted material und a more economical production.
For DLP 3D prints, liquid photopolymers are used as printing materials.
The SolFlex 3D printers are designed to be open systems. They are tested to work with materials of all leading material manufacturers. A custom-designed UV light source allows our customers to use a broad range of materials, such as clear transparent materials, biocompatible, and filled materials. Establishing strong partnerships with major material suppliers ensures cutting-edge material technology, quick and easy access to the newest applications and constant material improvement.
The software used in 3D printing is essential for the printing results. On the one hand, the software helps to prepare the objects for printing and on the other hand, it allows to navigate and monitor the printing process on the printer.
In terms of software, the SolFlex devices are compatible with most of the common slicing and nesting software packages such as Netfabb. A specially developed engine for Netfabb enables an intuitive positioning of 3D models as well as an automatic generation of minimally invasive support structures which results in reduced post-processing times.
The SolFlex family is characterized by the fact that all 3D printers are true standalone devices. Hence, print jobs can be started directly on the printer via a touch screen interface. After having created a print job, the file is transferred to the SolFlex 3D printer by using a network or USB port.
