Technology based on the first RepRap projects has grown so much that some people have already forgotten when, who and how it all started. Going to various forums, portals dedicated to 3D printing, we find a lot of information about important details and intricate details about RepRap, plastic, electronics, etc. The same machine variants have arisen so much that hardly anyone is aware of the whole ‘family’ (described quite scrupulously on the tree) genealogical ).
As every day I deal with students, I noticed that not all the things that are obvious to the old bend of 3D printing are clear to the total newbie. Fact, on the Internet you can find information on how to start ‘, various tutorials, etc., but most of them are quite old materials – and with such a rapid development of the subject, they are becoming obsolete at a dizzying pace.
This is the first thing every maker has to become familiar with. The issue of converting 3D files into physical ‘exhibits’ using the FDM technique has already been described in our pages here , and ‘do’s and dont’s’, which is what you can do with the models and what can not be done here .
What is this toolchain ? Well, drukarka 3d open source software is not yet in the version, all in one ‘, so we need several tools for the process of 3D modeling. These few small programs, or rather, programmers’, this is the toolchain. The process consists in ‘grinding’ the data from the model by each of them, and then sending the file to the printer and clicking ‘print’. This is best illustrated by the following picture
Having a 3D model, say created in Rhino (Blender, Solidworks, 3d studio or anything similar) and making sure that it meets the basic conditions – that is, waterproof, does not penetrate with itself, etc., save it to the STL format . Most CAD programs have these options, you just need to find them (search in, Save as .. ‘or’ Export ‘), it should also not be difficult.
The second, quite important thing: checking the correctness of the file . It is not necessary, but I recommend doing it every time, because then it is easiest to catch potential errors in the model. It is best to simply open the STL file with the free Netfabb program and view it from every page. If there is something wrong with it – a red exclamation mark will appear, as below. In this case, click the red cross (repair) and select the option “automatic repair” on the bottom right – most problems should be solved automatically.
