This gives you a great way of applying things like subdivision in a non-destructive way where you can come back and increase of reduce the subdivision level later and re-export a fresh copy of the model. When Blender exports a 3d model file for print, any modifiers and edge settings for the model are applied during export. 5) Use crease settings for sharp text edges The joins are cleaner with less crow’s-feet (v0.1 seemed to create a join with three vertices splayed out rather than one, v0.2 does a much cleaner job).
If you are using Booltool v0.1, I strongly recommend seeking out v0.2. Booltool is a great add-on to use for preparing 3d models for print.ĭespite Booltool v0.2 being released back in 2014, we only discovered it fairly recently. The built-in boolean modifiers do an adequate job, but it is worth getting Booltool by Vitor Balbio if you are doing a lot of 3d modelling for print. Use a Boolean Union to join your text to the main object. Move and orientate your text so that it intersects with the main model. This will avoid the disconnected faces issue above and save a few keystrokes. Convert the text to a mesh when it is still a flat 2d shape, and then extrude it to the desired thickness.To fix this, in Edit mode, select all vertices and from the menu, remove doubles. In this case, the front and back faces of the mesh will not be joined to the sides. set an extrude value in the properties panel before you convert the text to a mesh.To make the text solid, there are two methods to choose from.
If you want a bevel, wait until the text is converted to a mesh and extruded into a solid before adding a bevel modifier.
If you do, this creates weird edges and overlapping geometry when you convert the text to a mesh which you will have to clean up later. 2) Don’t Bevel the textĭo not set a Bevel on the text object. Easily keep track of scale and dimensions. If the guidelines say your text should stick out 0.8mm, then you know you need to extrude by at least 0.8 Blender units. This is really handy if you are working to guidelines dictated by the material you are printing in. Otherwise, any extrusions or other settings will get multiplied up by the scaling factor which makes life unnecessarily difficult. This way, if you add an extrusion to the text, 1 Blender unit = 1mm. Rather than scaling text in the main window, we recommend sizing the text with the size in the properties panel. We recommend using 1x Blender Unit = 1mm when preparing models for 3d print.
If you need a 3d model file to follow along with, you can download our photo frame model for free and modify it as much as you like.īe mindful of the scale and units. While 3d modelling from scratch takes time to learn, we show you an easy way to get started with Blender 3d printing text.Īdding text to an existing 3d model is of the easiest ways to make something unique and personal. Problem could be intersecting faces or non-manifold.Blender is a very powerful and flexible tool for creating and editing model files for 3d printing. Or zero faces - the size that trigger the “degenerate” test to result in that, if you would select all your mesh (in edit mode) scale it and you’ll see the toolbox will not find any “0 faces”. Like overhangs, it just informs you that there is a place that needs support. Not all warnings are dangerous for print. After that I used 3D-Print add-on and clicked make manifold. I went to edit mode selected all and triangulated faces. In your case, it needs some repairing after the boolean. When you set a right voxel size (by try and error) it makes your model clean for print, but in hight mesh density, so I usually use a decimate modifier after that, to make it more "light" to work with. ultimately, which iam using when working with a chaotic and more complicated models, there is an awesome voxel remesh. You can turn on a 3D-print addon where is an option to make manifold, also when in edit mode under mesh>clean up there is a few tools that deal with bad geometry. check if the normals are as they should be, by turn on face orientation in viewport overlays, any red is a bad sign. Go to edit mode select all and triangulate There is a lot, you can check before printing.
