![]() ![]() To certify that your shape is solid, turn on the Entity Info on the default tray and periodically select your group. Sometimes, all you need is an extra, nearly invisible point or edge to turn an interesting model into a non solid one, which will give unexpected or bad results upon the printing process. Errors are very easy to create in Sketchup. 3D printers require solid models, with non-manifold geometry and no holes in the mesh. 3D printers use millimetres as unit of measurement.ĥ. To make this process easier, we'll choose the architectural design - millimetres template. Sketchup Make is a very rigorous modeller, but we need to make sure our model is printable, that it's dimensions do not exceed those of the printer, and that small details are not too small for the printer resolution. ![]() Since we're creating for 3D printing, control over dimensions is very important. Hence this tutorial, showing how to use it to create a simple, 3D printable Sketchup model. However, at our level of teaching, Sketchup Make is the best tool. To be fair, Sketchup with its export to STL plug-in is amazing for simple pieces, and maybe the complete set of tools in the Professional version ease up the job of creating 3d printable hollow shells. From our experience, other applications, such as Tinkercad, are actually more suitable to enabling children to easily create 3D printable models. Sketchup's flexibility with geometry makes it easy to create complex and beautiful pieces that are a nightmare to prepare as prints. Unleashing this tool with children creates a specific set of difficulties, since they haven't yet acquired the necessary dexterity and rigor in modelling. And we have a lot of those buildings in Portugal.ģD printing with Sketchup has its pitfalls even for advanced users. Why church steeples, you ask? Well, if you combine a complex profile with a polygonal path in Sketchup's follow me tool, you end up with some pretty cool structures, very similar to the steeples in baroque churches. Usually I teach them to create a simple house in order for them to gain proficiency with Sketchup modelling tools, and then a dome/chess piece/church steeple to teach some more advanced techniques. This is about teaching young kids to use Sketchup Make, so it has to be simple, fast, and give quick results. This quite lengthy introduction serves as a justification for this basic tutorial. To put it in another way: when preparing children for an uncertain future of fast evolving technologies, is it more important to train them as Microsoft office ninjas, or to foster inquisitive minds and flexibility with digital tools? As a result of these ideas, my class is one of those rare ones where students enter without prior knowledge of the subject and exit a few weeks later holding their own 3D printed objects in their hands. ![]() Our focus is not in training accomplished 3D modellers or designers, but in the broadening of young children's horizons. And, in the case of Sketchup, they love using it. In our specific case, we took a good look at the curricular goals for ICT, which are generally achieved with internet research and office tools, and asked ourselves what would be more interesting: challenging pupils to create multimedia projects using office tools, or 3D modelling programs? The learning goals are the same, but the more advanced tools used give our students a broader horizon, enabling them work in projects that are far from their personal experiences. ICT class is about exposing our students to digital technology, teaching them the basics of computer use, and challenging them to learn work methodologies with digital tools. ![]() Sketchup Make is used extensively by my 11-12 year old pupils, as well as other 3D modelling apps and a 3D printer. I'm a schoolteacher, teaching Information and Communications Technology (ICT) in a Portuguese school. This tutorial is not for you, advanced users. Readers of this magazine may find this Sketchup Make tutorial a bit too simple, very elementary, and below the usual standards of the tips and tricks shared here by advanced users. ![]()
