An introduction to 3 D printing

• A (very) brief look at 3 D printing methods. • How Fused Deposition Modelling (FDM) works. • Introducing Open. SCAD. • Designing your first 3 D object. • From file to physical object – how things actually get printed. • 3 D printing tips and techniques. • Ready-made models.

How does FDM work?

Open. SCAD • • Open Source All platforms Simple to use Design complex objects

You can even 3 D print… A 3 D printer!

(But let’s not get ahead of ourselves just yet…) Open. SCAD lets you create simple 3 D geometric shapes. cube([50, 50; ([ cylinder(h=30, r 1=10, r 2=10) sphere(30)

And then use functions to combine shapes into complex objects… rotate([45, 0, 0([ cube([50, 50, 50; ([ translate([100, 0, 0([ cube([50, 50; ([

Different functions can add objects together. Or take them away. difference(){} union(){} Takes one object away from another Joins two objects together

And now it’s time for a live demo…

Once your design is finished, it needs to be ‘sliced’ for the 3 D printer. Finished Open. SCAD design stl file Design imported into slicing software. (Cura) GCODE file

And now it’s your turn!

A final few words… Thank you for coming today! Please leave us feedback via knowledgemakers@googlegroups. com Our next Knowledge Makers meetup will be on June 28 th You can also create, share and download some amazing 3 D designs on http: //www. thingiverse. com
