ABSTRACT
In 2013 at the Print show in New York, XYZ Workshop launched the longest three-dimensional (3D) printed dress created at that time using a desktop printer. There are four basic types of 3D printing methods at this time: fused deposition modelling (FDM), stereolithography (SLA), granular materials binding (GMB), and selective deposition lamination (SDL). Syringe-style extrusion is essentially FDM printing except that the traditional extruder has been replaced with a pressurized syringe which allows for the extrusion of pliable materials – anything from soft foods to clay. SLA printers typically print more quickly than FDM printers, especially the digital light processing (DLP) variety. DLP machines print in seconds per layer by printing a full layer at once, instead of drawing it out line by line. In addition to syringe-style printing, edible products can also be printed with GMB technology. SDL prints are extremely strong and durable – especially after applying thin layers of Super Glue to the object.
