![]() ![]() To ensure the model you designed or imported does not have holes, the model must be made water-tight by the right tool. 3D printer usually cannot print such model. Often the design may appear to be a solid, but if there is any holes in the exterior surface, the model becomes a hollow shell with surfaces that have zero thickness. Now that we have a good looking model at the right size, the model must be made into a solid before printing, otherwise it is just a group of surfaces, or mesh. Now let’s make sure we save the model as a 123D Design file, but also export is as an STL file. After a few iterations, a 7.5cm wide Darth Vader model is achieved. More often than not, the translation tool and the scaling tools need to be used iteratively to bring out the desired result. To remove the offset, simply use the translation tool to move the scaled model down more. Now, notice the scaling will introduce more offsets. To scale Darth Vador down to size, use the scale tool: Darth Vader scaled. The Darth Vador above is rather large, as is evident by the fact the ground plane, which has a millimeter grid, is so dense that it becomes a solid plane. Autodesk 123D Design can be used scale the volume. If you import a model from an external source, often the model needs to be scaled to fit within the printer’s build volume, and your desired size. If you designed the model using the units that you actually wants to use, then this step may not be required. Darth Vader brough near origin, unscaled. Using the tranlation/rotation feature and viewing perspective cube (top-right) to bring model down to near the origin. To fix the problem using the translation and rotation feature and to viewing perspective cube at the top-right to bring Darth Vader down to the ground plane. Take the Darth Vader model below for example, after importing it into Autodesk 123D Design, one will find that it is well above the ground plane. TranslatingĪfter important a model, it is often necessary to translate the model to the origin before working with it. ![]() This blog post describes some of the most important ones. After you created or imported a 3D model, some preparation is usually required to make it 3D printer friendly. ![]()
