The process of producing high-quality prints can be difficult, despite the apparent simplicity of 3D printing. An important component is “pressure advance,” which modifies the filament feed speed to lessen printing artefacts when the print head changes speed.
The correct pressure advance level has until now been determined empirically. However, Mike Abbott, an engineer, has created the novel Rubedo system, which automates pressure advance calibration.
Laser triangulation is carried out by Rubedo using a laser line generator and a camera mounted on the printer’s extruder. Using OpenCV software, the system scans a test print that contains several lines printed at various pressure advance values to find bulges and thinning brought on by speed changes while printing.
Abbott’s Rubedo system offers a solution to a long-standing issue in the 3D printing industry. His method saves time and yields prints of higher quality. In a video, the system’s design is thoroughly described and demonstrated in action.
Overall, Abbott’s work represents a significant step forward in the field of 3D printing. By automating pressure advance calibration, Rubedo streamlines the printing process and makes it easier to achieve high-quality results.
