![]() ![]() The tool’s simplicity of use means that engineers and others involved in product development can become fully conversant with the software within minutes, rather than the weeks or months required to become skilled with traditional 3D CAD tools. Developed in conjunction with SpaceClaim, the leading provider of flexible and powerful 3D modelling software for engineers, DesignSpark Mechanical overcomes two major barriers to entry faced by potential users that are new to 3D design: prohibitive cost and the considerable investment in learning time associated with traditional 3D CAD tools.īased on ‘direct modelling’ technology, users can create geometry easily with powerful and intuitive gesture-based modelling techniques. Even though the little knob at the tip of the finial prints solid, it isn't very strong and can break off easily, so be careful.Available completely free of charge, DesignSpark Mechanical is a powerful 3D CAD modelling software tool that is very easy to learn, and provides a highly intuitive user experience to help engineers create design concepts in 3D faster than ever before. I printed using ABS with 0.2 mm layers and 40% infill for strength, and of course, I used support material. The finial will need support material when it prints, and after it is removed, the underside of overhanging surfaces will be rough- you'll have to do a little sanding. ![]() I chose the first option and printed a small cylinder along with the finials. ![]() The first option wastes a small amount of filament, the second can be tricky because plastic can drool out of the nozzle while it is waiting and that will put a blob of plastic on the print every time it starts a new layer. You can print an additional object at least as tall as the finials to give the printer something to do while the tiny finial parts cool between layers, or you can add custom gcode for every layer change that just makes the printer wait for maybe 10-20 seconds to start printing after each layer change. There are a couple ways to prevent the print quality problems that printing tiny layers can cause. If the nozzle goes back to a small area before it has had a chance to cool, you'll end up with a blob. Notice that when the printer gets to the top of the print, the area on each finial will be very small and will complete printing quickly. ![]() I printed four of these at the same time using ABS. ![]()
