The time required to model a single component and then develop the component’s family consumes a great deal of time and is a strenuous task. Thus, making it more appropriate to design open source hardware for scientific equipment. The main benefits are being able to export to standard parametric models using Python language with its libraries and the ability to use and integrate the models in its graphical interface. Our findings show that although Python for FreeCAD is more arduous to learn, its advantages counterbalance the initial difficulties. We have created a parametric open source hardware design to compare these tools. In this work we analyze OpenSCAD and compare it with FreeCAD Python scripts. This is an important deficiency because it is key to share the design in the most accessible formats with no information loss. However, OpenSCAD lacks the ability to export to standard parametric formats thus, the parametric dimensional information of the model is lost. OpenSCAD is the most widely used scripting tool for parametric modeling of open source labware. Parametric design using a solid modeling programming language allows customization and provides a source file for the design. In addition, parametric modeling is encouraged in order to facilitate customization for other experiments. PLA is used as a feedstock material in desktop fused filament fabrication 3D printers.Open source hardware for scientific equipment needs to provide source files and enough documentation to allow the study, replication and modification of the design. In 2010, PLA had the second highest consumption volume of any bioplastic of the world. 3Polylactic acid or polylactide (PLA) is a thermoplastic aliphatic polyester derived from renewable biomass, typically from fermented plant starch such as from corn, cassava, sugarcane or sugar beet pulp.3D printers, laser cutters, milling machines and many other technologies can be used to physically create the files shared by the users on Thingiverse.

It is free software and available for Linux/UNIX, MS Windows and Mac OS X. 1OpenSCAD is software for creating solid 3D CAD objects.In this case I only changed the variables following the instruction inside and this is the final version: Label for mailbox in OpenSCAD The printed label for mailbox Even this time I found a solution in Label on Thingiverse. I usually put a paper label on my outdoor mailbox, but I needed a new one more strong, maybe printed in grey PLA 3 Translate() cylinder(r=7.75, h=bone_height) Translate() cylinder(h=bone_height, r=16) My modified script (in bold my changes): $fa=1 īone_height = 6 //set this to how thick you want the tag I changed some dimensions of it and added the back side in order to have two different phone numbers, this is my final and adapted version: Dog tag in OpenSCAD Dog tag front view Dog tag back view I found Reinforced Dog Tag on Thingiverse. So I do another one this time with my 3D printer. The metal tag of my dog was broken and it was necessary that my dog has new one, because he usually tries escape from my garden and goes into the public streets. So I have adapted two things downloaded from Thingiverse 2

You have full control over the modelling process and enables you to easily change any step in the modelling process or make designs that are defined by configurable parameters. And it is very easy to do, because it reads a script file, very easy to understand, that describes the object and renders the 3D model. With OpenSCAD and the parametric design you have to simply edit a text or a variable in a editor and after a render you can save the STL file, ready to the slicer! I will show you two examples that have facilitated my life.Įxpert, but looking in Thingiverse I have found a lot of things than can be edited using this opensource software. In these cases you can model from zero your object or try to edit it directly in your software. Sometimes you have to change a little aspect, as the text or one or more dimensions, of your object before printing.
