What is 3D printing?

What is 3D printing? Creating products by forming successive layers of material based on 3D Data

Example https://en.wikipedia.org/wiki/3D_printing

What is required for 3D Printing?

What is required for 3D printing? 3D Printer 3D Data

How to create 3D Data?

3D Data Examp l e STL(ASCII)

Definition of Triang l e (po l ygon)

Definition of Triang l e (po l ygon) Successive triang l e definitions

Format is so simple

But creating 3D Data from scratch is so hard task

3DCG/CAD software

Many 3D software provides Python API

Many 3D software provides Python API You can manipulate 3D data via Python

Script Modeling ‣ You can create 3D mode l even if you are not fami l iar with 3DCG/CAD software ‣ You can create shapes that are difficu l t for hand creation ‣ Modifying shape is easy

Script Modeling with Blender and Python

What is Blender? • Deve l oped since 199 5 • Open source software, Mu l ti p l atform • Language: C, C ++ , Python ‣ Python is used as API interface ‣ B l ender has its own python interpreter in the software （ 3.5. 1 in B l ender 2 . 77 a ） asyncio!!

Connect b l ender and minecraft wor l d using Python

Convert this kind of 3D data to Minecraft B l ocks!!

Implementation Overview Consists of two main pars. Convert 3D mode l Transport b l ocks into B l ocks into Minecraft Converting Transporting

Script Modeling with OpenSCAD and Python

What is OpenSCAD? • CAD software, Open source (GPL) • Mu l ti p l atform （ Win, Mac, Linux ） • Imp l emented by C ++ (Qt) • Create 3D mode l using origina l programming l anguage • No GUI to manipu l ate 3D data

Feature of OpenSCAD • Very good for Software Engineer • Written script can be kicked from command l ine ‣ Generate mode l in Server ‣ Create mu l tip l e mode l with command

Neck tie composed of mu l tip l e characters

Generate by 1 command ‣ You can pass arguments from command l ine to OpenSCAD script

OpenPySCAD • Generate OpenSCAD code from Python code ‣ https://github.com/taxpon/openpyscad • Insta ll via pip command $ pip install openpyscad

OpenPySCAD • Union operation Cube([20, 10, 10]) + Cube([10, 20, 10]) union(){ 
 cube([20, 10, 10]) 
 cube([10, 20, 10]) 
 };

OpenPySCAD • Difference operation Cube([20, 10, 10]) - Cube([10, 20, 10]) difference(){ 
 cube([20, 10, 10]) 
 cube([10, 20, 10]) 
 };

OpenPySCAD • Rotation c1 = Cube([20, 10, 10]) c1.rotate([0, 0, 45]) rotate([0, 0, 45]){ 
 cube([20, 10, 10]) 
 };

Conclusion

Script Mode l ing is FUN!! Script Modeling is FUN!! • Let's start tody Let’s start today https://flic.kr/p/ef4VBP CC BY 2.0
