Computer controlled motors move the nozzle around to create the shape of your object one layer at a time from the bottom up. The filament comes on a spool and is fed through a heated extruder nozzle. Our 3D printers use PLA (short for Polylactic Acid) Filament, which is a biodegradable thermoplastic polymer made from plant starch. How does it work?ģD Printing is also known as additive manufacturing because the physical model is built up one layer at a time. The process teaches accuracy, three-dimensional thinking, and working within the design constraints of the 3D printer. Putting it simply, you draft an idea beginning with a sketch and finish with a 3D physical object. With a 3D printer, library patrons can create 3D models by using computer software to build an exact replica of that model in plastic. To schedule a 3D printing appointment at your local branch, call or visit to see what services are currently being offered.ģD printing is the process of making a physical object from a digital model. Sonoma County Library is developing a program to make 3D Printers and classes part of our commitment to providing our residents with access to a variety of technologies in order to acquire new skills, explore new possibilities, and make informed consumer decisions with technology.
