Use of robotic additive manufacturing for the shaping potentials lattice geometries from extruded biopolymers
Author(s): Cesar Bacca
In the research carried out for the development of a robotic additive manufacturing process, rectangular prisms were manufactured from a biopolymer composed of water, glycerin and corn starch. In a first stage, experimental test benches were implemented to select the extruder components and also to define the raw material combination: starch percentage (15%, 20% and 25%) and glycerin percentage (0%, 15% and 30%). The material was extruded at two pressure levels and at five extruder speed levels, obtaining extrusion speed ranges, the rate of extruded material and the extrusion diameter of the material. In a second stage, these parameters were adapted to control the positioning of the extruded material by means of an 8DOF robotic platform, and thus define impressions with lattice-type sha... view more»
