Introduction: Silicone 3D-printing for Negative Silicone Mold
/ * The processing of silicone provides the possibility of negative silicone moldings.
3D printing is carried out with the silicone negative-form processing for the reproduction technique.
"serial 3D-printing" in the sense of lithography or analogue photography. Silicone negative molds can be used to cast various materials. The Silicone Machine can be used to connect a 300-ml silicone cartridges, which can be purchased at any hardware store, to a 3D printer and process silicone. Two Nema 17 motors, which are adapted to the 3D printer, press the silicone out of the cartridge. The silicone enters a special extruder and is extruded. The extruder can be connected to the usual FTM 3D printers, such as: - Makerbot Replicator 2 / 2X - Ultimate 2+ - Prusa i3 - etc ... The silicone machine stands apart from the 3D printer as an addition to the 3D printer.

Step 5: Serial 3D Printing
Since prehistoric times things were copied, rebuild and rearranged, books were transcribed manually before the invention of the printing press. Reproduction technologies are evolving out of a long history of previous techniques like lithography and photography. The “serial 3D printing” is a contemporary version that is enhanced with a negative silicone mold. Meaning that this negative form is generated based on its digital replica. The printed silicone negative mold is the origin for the subsequent series. As the negative film is the origin for the analogue image the negative silicone mold is the origin for the physically produced series.
Step 6: MANIFESTO - Serial 3D-Printing
Bremen, Juli 2015 author: Vincent Brinkmann
1/9 The one who does serial 3D printing sees himself as the producer of a series that is generated from digital data. With help of 3D printing a mold version is made.
2/9 The mold version is directly produced from digital data so there is no for a physically existing positive version.
3/9 The creating act is the cast of the objects. The producer decides which material is being used.
4/9 The casting itself becomes a ritual. In the making of a series the cast turns into a connection between its creator and the object and, through the serial repetition production becomes a ritual.
5/9 The series is produced by a number of copies determined by the artist. The copies are numbered with the appropriate total number.
6/9 Serial 3D printing critically reflects the handling of mass production. Mass production serves as artificial divergence, as the initial point of difference between object and repetition out of which a series is created.
7/9 The trace turns into the patina of the shape and is embedded in the object. The technique of reproduction remains visible.
8/9 Mistakes happen. In the technique of reproduction of serial 3D printing you cast from a mold form; all casts are unique and individual.
9/9 Serial 3D printing becomes the valid technique of art that must spread and find application.
