Is a non-contact process which utilizes a laser to cut materials, resulting in high quality, dimensionally accurate cuts. The process works by directing the laser beam through a nozzle to the work piece. A combination of heat and pressure creates the cutting action. The material melts, burns, vaporizes, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.

Abstract
Teaching descriptive geometry, in the context of this study, is characterized by the continuous investment in recognizing digital representation technologies which can enhance the didactic activities in architectural training. This study describes this trajectory which includes the use of virtual reality, augmented reality and parametric modelling, as well as freehand drawing and the production of physical models both by automating the unfolding process and by digital fabrication processes of 3D printing and laser cutting. In addition to questioning the relevance and sustainability of the infrastructure needed to ensure the continuation of this trajectory, the potentialities identified in each of the learning activities that have been structure, are shown. Although these potentialities are specific to this context, it is considered that this type of record contributes to understand the issues being faced in teaching practices.
