I show these in the video demonstrating how I could adjust the angle of the parts easier than when it was created as a single body. I discovered how it makes the design easier and made it so that it could be adjusted afterwards. I then experimented using the Part workbench, creating the arm from different bodies and also using the simple 3D shapes such as the cylinder. I tried to modify my existing design, but making adjustments broke other bits of the design and broke the overall CAD model. This was easy enough to design but I realised I'd made the arm too big and so it wasn't very stable. In my first attempt I made the arm using just the part design workbench. I created it as a two part arm so as to also provide additional adjustment. I found a small clip-on fan, but it has limited movement so I couldn't position it where I wanted to. I've therefore created this follow-on video based around using the FreeCAD Part Workbench Creating a Fan Extension Arm to 3D Printĭue to a heatwave in the UK I've been trying to find a suitable fan to cool my son. You can see my earlier video: Beginners FreeCAD tutorials, or my other 3D printer / CAD projects. I've already created a beginner video, but I found there were not many videos that explain the next step of how to create more complex models from multiple parts. This can make it difficult for beginners faced with a steep learning curve to learn the concept before they can put it into practice. It is a 3D parametric modeller, which means that models are designed by adding constraints that determine the relationship between shapes and dimensions. Being an Open Source software, this 3D CAD software presents the advantage to be entirely modular, thus you can add your own Python functionalities if needed, either download it and add it as a macro.Creating 3D CAD designs in FreeCAD - Using the Parts WorkbenchįreeCAD is an open source 3D design program available for Linux and Windows. Adapted to do-it-yourself projects or to light corporate modeling, FreeCAD allows to make a layout, has functionalities (modules) for robotic, architecture, and has also a finite elements calculations module. To get more information on the basics of this 3D modeling software, you can look for a video tutorial for FreeCAD on YouTube, for instance.įreeCAD is an Open Source software, completely free. We won’t have the opportunity to present in details the Freecad design features step by step. Nevertheless, it’s important to manage the main functionalities as we will here be focused on good design practices to create 3D models for 3D printing. You don’t need to be an expert in Freecad to follow and understand that 3D design tutorial. STL format is the reading format for 3D printers, Freecad is adapted for designing for 3D printing. With FreeCAD, it’s possible to directly export to. The operations sequence is accessible in the arborescence, which permits to modify at any time, the sizing of the manipulated parts. Written in Python, Freecad has a parametric functioning. In that way, this 3D design program is an excellent tool for modeling a functional part which you have already in mind. ( eg : each point of the drawing has a specific coordinate). It’s based on geometric shapes manipulation (entirely sized) or constraints sketches. To analyse and export in an optimal way your 3D fileįreecad is a 3D modeling software oriented to industrial design.Thus in this 3D modeling software tutorial, you will learn best practices to model, correct and export a part for 3D printing. With that FreeCAD tutorial they will learn some tips to realize a printable model with that software. This tutorial has been realized for FreeCAD users interested in 3D printing.
