Blender has supported 3D printing modeling and file formats since 2002. However, with Blender version 2.67 this now is even more accessible and powerful, thanks to the 3D Printing Toolbox and real-time Mesh Analysis features.
Dolf Veenvliet is a Dutch artist who has been exploring 3D printing for sculpture design for many years. He is an enthusiastic user of Blender, owns a MakerBot printer, and is a big fan of anything open and shared. On his website macouno.com you can find many examples of his work.
In this case, I took the male and female thread objects in this file and printed them. Then I printed the male thread part at 99% and 98% size and tried all three. When they were done printing, I could not get any of the male objects to screw into the female threads more than, at most, half a turn, and then, they fight in quite tightly.
Ive been trying to use blender for a 3d print project. Somewhat new to blender and very new to 3d printing in general. Blender is a bit painful to work with in few respects. Imagine trying to create an object like a bottle. It has curves and an inner/outer surface. Most tutorials sugest creating the outline and then either the spin tool or the screw modifier. Both options can generate a bottle like model. Ive also tried using a cylinder and extruding upward along a path. The model looks fine with all 3 methods. Then you try to bisect it and everything goes wrong. Its not a solid shape and bisecting reaveals all manner of artifacts. I want to basically split it down the center to create 2 parts. Then I want to add some pegs so the parts fit together. Once again Im relatively new to blender and a pro might bang this out in a few minutes. But for me Ill definitely try the above alternatives. This article describes the pitfalls of surface based modeling vs solid modeling and is the exact issue Im hitting. I have no confidence if I print my blender model it will work. Then again this will be my second 3d print ever. Thanks for the article.
I have successfully built the facial object in blender but my problem is that it just won't print after i've sliced it in cura, perhaps because it doesn't seem to be watertight. I have tried mesh repairs and other things in blender but nothing seems to work.
How do you handle the clothes / Armour / object of the character?
I model them as separate objects, and the body mesh is separate. Do we need to make it one Continuing mesh? For example how would you do a skirt and hair mesh for a model for printing?
If this is the wrong place to put this post, I apologise. I couldn't find anywhere on the Blender site to do with 3d printing, so I thought I'd try here. Please point me in the right direction if there is one here!
Above is a 22mm M4 bolt with a nut printed at a 6% x/y increase, as per nikolai-r, neophyl and Zoltan suggestions, and while I wouldn't describe it as a loose fit, the nut does fit finger-tight all the way up. This was printed at 215/200C in 0.09mm layers (0.2 for the first). I made the thread deeper than the default settings in Bolt Factory, and set the pitch at 0.85mm to improve separation of the thread while printing.
Blender is a popular CAD software that people use to create unique and detailed designs, but people wonder whether Blender is good for 3D printing. I decided to write an article answering this question, as well as giving more useful information that you can use.
The key to creating printable models is making sure they contain no errors which could impede the printing process and being able to export them as STL (*.stl) files. Both conditions can be fulfilled using Blender.
As Blender is such a popular program among creatives, there are many courses available online, and they cover numerous topics, including 3D printing. Chances are, if you were facing an issue related to 3D printing in Blender, someone has had it before and found a solution for it.
There are also more complex courses tailored to more specific interests, for example this paid course called Blender to Printer that has a general Blender learning version and a 3D printing for character costumes version.
It also includes 3D reconstruction, photo scanning and printing, which is an interesting bonus. It is taught on an example-based approach, which some people might find more helpful than a more general overview.
This focuses more on the steps you need to take to ensure an existing model is suitable for printing. The teacher is using a previously created model and analyzes it to see if it is watertight or if it is strong enough to be printed.
This course provides a complete overview of Blender modelling and printing. According to its description, it is suitable for both beginners and more advanced users course including both introduction to 3D modelling and awareness of 3D printing issues.
Once you have an idea of the tools available to you, as well as a reference, you can start modelling or sculpting, depending on your preference and the kind of object you want to create. I added some videos at the end of this section that walk you through modelling in Blender for 3D printing.
Once you finish your model, there are a few things to check to ensure smooth 3D printing, such as making sure your model is watertight (joining all the meshes in the model into one using CTRL+J) and checking for non-manifold geometry (geometry that cannot exist in real life).
FreeCAD is a better option for 3D printing if you want to create more rigid and mechanical real-life objects. It makes setup for 3D printing easier, because of its accuracy, however it is not the best when it comes to designing more organic or artistic models.
From a 3D printing point of view, both programs can import, modify and export STL files, although FreeCAD models need to be converted into meshes before being exported. Much like Blender, FreeCAD allows you to check whether your geometry can be printed properly.
Thus, FreeCAD is a better option for you if you are designing more rigid parts and need dimensional precision. It offers accessible Workbenches to assist in fulfilling the 3D printing requirements, including ensuring proper meshing.
The 3D Print Toolbox is an Add-on that comes with the software itself and contains tools for getting your model ready for 3D printing. Its primary benefit for the users is checking for and fixing errors in Blender models so that they can be exported and printed successfully.
The 3D Print Toolbox offers useful tools for ensuring the 3D printing process will go smoothly, and there are many detailed tutorials about how to use it, here is one for Blender 2.8 which I found useful.
The model would either appear too big or too small on the printing bed. The reason for this issue is that Cura is assumes the units of the STL files are millimeters, and therefore if you work in meters in Blender, in the slicer the model may appear too small.
3D Printing computer-animated replacement parts for stop-motion films is slowly becoming a standard for big animation studios. But for smaller productions and individual stop-motion artists, it is still a new and unexplored area. Studio Fantasmagoria in Tbilisi, Georgia developed a workflow for animating facial expressions in Blender and 3D printing them as separate objects for each frame.
Since the model seems to be not airtight, what would be the cause of this? Do I possibly have duplicate vertices that need to be merged or something? As for manifold, am I supposed to be modeling the hollow bits inside my model? I know blender has a solidify modifier that does this.
So I got a chance to mess around in blender a little bit more, and it definitely was my model I built having poorly connected edges. I have been messing with OpenSCAD and have been digging that for less organic modeling. The STL sizing issue makes sense that it would be incorrect depending how the model was imported and by what.
Ram Singh is the author of this video series where he teaches Blender in 7 days. You can easily see how dexterous he is in the tool after a few minutes watching it and I personally liked the pace of the course which is not slow and you can learn a lot in a short period of time. For 3D printing you will need at least to watch the series until day 3, covering the basics, editing objects and modifiers.
The first step is to get rid of elements we don't need in 3D printing, which are the camera and light. To delete them, just select them in the right sidebar, the one with the Scene Collection, and press X while selecting camera and light or use the context menu.
I am currently doing a project with 3d printing.
That means all my geometries are based on curves.
If I want to export something for rendering it has to have a thickness right? So I tried just piping the whole curve, but that makes my exported .obj file 3GB big.
I'll preface this by saying that up until very recently, all of my 3D modelling experience has been in Sketchup for the purpose of 3D printing. When you're modelling for printing, you ideally want to remove ALL internal lines/faces, otherwise it can cause undesirable effects when slicing.
In this case, when I check the design it shows that the bottom face is an overhang face (shown with yellow color). However, if I change the overhang parameter in 3D printing tool box from 45 to 90 and then check the model, it doesn't show any overhang faces and it seems that everything is okay. I don't think increasing the overhang parameter could be a good idea. However, this is my first time that I'm trying to design a model for 3D printing. Can this model with the overhang parameter equal to 90 be printed using a 3D printer? How can I fix the overhang problem in this simple model.
