A Brief Guide to Constructing Your Own Blast Furnace for Metal Casting and Rapid Manufacturing. The detailed overview of this project is available at http://open3dp.me.washington.edu/2014/10/rapid-manufacturing-iteration-and-industry/. To observe the assembly in action, please refer to the accompanying video: https://www.youtube.com/watch?v=FaLqah1V5_s. Step 1: Begin by ensuring that you have accurately defined the parameters within your SCAD file, as this will affect the outcome of your 3D printing process. Convert your compiled .stl model into a workable design for assembly. The burner intake designs offered, burnersIntakeMK6 and others, cater specifically to various metal types and pipe diameters. Take note that thread-cutting onto black pipe with an inner diameter of approximately 0.87 inches (or 3/4 inch) is recommended before any further threading. For cast bronze applications using MK7 designs, set the intake at a constant width of 3/8 inches and ID tolerance is tightened by .004". In contrast, MK8 intakes follow proportional sizes while maintaining an increased ID tolerance of 0.010" tighter than the original setting. When inspecting the SCAD code for the furnace assembly, users may employ specific syntax such as "#%" to enhance visualization, particularly when identifying modules and module interfaces. For metal preparation and assembly requirements, cut steel sections to desired specifications can be efficiently handled at local steel yards, with costs ranging from $20-$25 per service. These sections can then either be tapped or welded for proper fitting, making sure that they fit precisely as specified by the SCAD designs. Upon completing these pieces, cover them in kaowool refractory material available through various sources including Seattle Pottery Supply and other local providers specializing in furnaces to seal the interior from any heat damage, ultimately resulting in a blast furnace perfectly prepared for metal casting or rapid manufacturing tasks.
