Difficulties of printing 3 D printing methodology 10

Difficulties of printing § Overhanging elements § Narrow Places HARD TO HANDLE SUPPORT 3 D printing methodology 11

Simple steps to make your object: § Different software was compared: – 3 D modeling software: § Be creative 3 DS Max, Autodesk Maya, Blender, Zbrush, Cinema 4 D – Slicer software: § Choose software for 3 D object creation Print the model Slic 3 r, Craftware, 3 DPrinter. OS, Cura § FDM (Fused Deposition Modeling) printing method was chosen, because of its availability § You can use different materials for your model and also combine few 3 D Printing Choose material Choose the slicerprogram Create a 3 D object Export file in. STL format Choose the method of 3 D-printing 3 D printing methodology 12

3 D creation software comparison Software Advantages Disadvantages - High entry threshold Different file formats support User-friendly interface - 2. 141, 70 € / year (free for Educ. ) - All panels have customization A lot of simply ways to solve nonstandard problems - Bugs Blender - Huge amount of tools Free Wide area of usage - Hard to learn Bad for beginners Zbrush - Best for sculpting High entry threshold Progress timeline - Not for animation Commonly you should use another software after to rebuild polygonal mesh Cinema 4 D - Very user-friendly Perfect rendering quality Software-friendly - Sculpting Full potential only with plugins 3 DS Max Autodesk Maya 3 D printing methodology 13

Slicer software comparison Software Advantages Slic 3 r Craftware - Real-time slicing Fast also on low-end PC Very user-friendly - User-friendly interface Software operates fast and is very easy to use Live visual feedback 3 DPrinter. OS Cura 3 D printing methodology Disadvantages - There are no print time and material estimates so far - Minor bugs (still in development) - Once your G-Code is generated, you can preview it - Premium features, that should be free - Easy for beginners Fast GUI Handles huge STL moderately fast - Some minor features missing Print time estimates are sometimes off around 10 – 20 percent 14
