Class Description

Session 1: Overview of slicing 3D models, its applications, and the basic principles behind it. Dive into essential safety protocols for operating your Glowforge with glass, covering eye protection, ventilation, and handling techniques. Discussion - different types of 3D models and their suitability for slicing. Show sources of 3D models and learn about the materials that can be used for slicing and how to assemble the 3D model. Detailed overview of a CO2 laser engraver like the Glowforge machine, including its components and functionalities. Introduction to laser engraver software interface. Explore the interface of your laser software, focusing on design creation, importing graphics, and optimizing settings for glass engraving. Introduction to slicing software. Get hands-on with slice positions and slice thickness, experimenting with settings to understand sizing and aesthetics. Session 2: Exploration of slicing techniques for laser engraving. Learn techniques for creating custom artwork. Delve deeper into laser settings for fine details, achieving layer effects, and exploring specialized techniques like raster engraving. Understand how to adjust power and speed settings of the laser engraver for different materials and in particular types of glass for trophies. Discover post-processing techniques for assembling and finishing your model, adding that professional touch.
