In the images above we can see the designs of Raul Polit Casillas, a systems engineer at NASA's Jet Propulsion Laboratory in Pasadena, California. The parameters that worked for me in this experiments were: Since you are working with strict rules and small tolerances you should make sure to print your model in high qualities (between 0.10 and 0.20 mm layer thickness).
Do not activate the supports function when performing the gcode (these could affect the prototype functionality).And to make the model bigger, ensure that the distance under the bridges is no more than 10 mm.To make the figure smaller, ensure that the staple thickness is at least equal to 1 outer perimeter + 1 inner perimeter (approximately 1.6 mm).To determine this, you need to experiment with the G-code and the 3D print's functionality. When it comes to scaling the model, you must consider the smallest possible size for the modules and the feasibility of the scaling. You can use it as a reference in your projects to verify that your 3D models adhere to the design guidelines and also you can get your own copy of the poster by requesting it through the official HUBS website: here.įor this project, the most "restrictive" rules in our design will be: But instead of seeing the rules as a restriction, let's see them as an advantage taking their qualities and using them to our favor to make functional parts.īelow are the full-scale 3D models I made with Tinkercad 3D Designs based on the HUBS poster "Design Rules for 3D Printing". By following these guidelines, designers can optimize their designs for 3D printing, improve the quality of the finished product, and streamline the 3D printing process. The goal of these rules is to help 3D designers create models that can be successfully printed, with good structural integrity and appearance, and without the need for excessive material or support structures. These rules provide recommendations for factors such as design simplicity, orientation, tolerance, wall thickness, infill, and support structures. The 3D design rules from 3D Hubs are a set of guidelines designed to help ensure successful 3D printing of digital designs.
