This instructable is designed to give users new to 3d printing some qucik tips and techniques to create better designs suitable for Desktop FDM 3D printing in the software ZBrush from Pixologic. This instructable assumes the reader has some knowledge in navigating the ZBrush interface. The transpose tool can be used for more than moving,scaling, or rotating your design.
It can also display ticks on its line so that it can be used for measurements. A perfect fit shown in the software does not mean a perfect fit after 3d printing. Because 3d design software ignores the friction and material inaccuracies present in the real world. Therefore for snap fits, always leave at least 0. For looser fittings such as hinges or chainmail, the spacing between your surfaces is crucial. A minimum space of 0. Setting up your transpose tool for measuring can help give you accurate spacing between your design's parts.
When sculpting details onto your model, it is recommended to slightly exaggerate details for 3d printing. This means making your surface details with slightly deeper cuts and more pronounced surface texture.
It also means making slender parts slightly thicker. Printing resolution limitations. Most desktops FDM printers available today come with a 0. As a result you can lose shallow engraved or embossed surface details.
For standard FDM printer it is recommend to apply details with a minimal depth or height of 1 mm for best results. Note parts under 3 mm in thickness are prone to breakage during and after printer, especially when removing print supports. If your mesh is under polygons in Zbrush even after using Decimation plugin to optimize mesh you can use the Clay Polish tool to estimate potentially how much detail you will lose during 3d printing on a desktop FDM printer with a standard 0.
High poly models are nice, but a design with a resolution that is too high can bog down a computer processing power and the exported files can be too large in size for a 3d printer slicer software to handle.
DynaMesh allows you to maintain the uniform resolution and polygon distribution of your mesh. ZRemesher will recreate a new polygonal structure for your model, with a controlled flow of polygons and a global polycount value.
In just a few seconds you can convert a , polygon DynaMesh to a 10, poly retopologized model with a natural flow of polygons. From there you can project all the fine details from your original sculpture.
When designing an object you would like to print in a FDM material such as ABS or PLA, keep this safe zone in mind if you are concerned your model will require support to be constructed.
Your ZBrush 3D model typically has an incredible level of detail — and is therefore also quite heavy. While this is perfectly fine when modeling within ZBrush, it can make things tricky when you want to export your file to different software or if you want to 3D print it. With i. In a nutshell, this plugin allows you to greatly reduce the poly count of a model while preserving the high-resolution detail.
Printers typically do not need any detail information that is smaller than 0. Avoid increasing the file resolution to more than 0. We have a dedicated tutorial about file resolution here , in case you want to learn more about this. In the image below you can see an original ZBrush file with a poly count of 11,, left , and an optimized 3D model with a polygon count of , While this dramatically reduces the file size, the level of detail practically stays untouched.
