What is 3D Printing?
3D Printing is taking a design, whether it’s from a CAD package, a drawing package or even a scanned image. It may be commercial or freeware, it doesn’t matter, as long as you can save or export an STL file.
You can check, clean or orientate an object in programs such as Netfabb, Meshmixer or any one of the other programs available.
You can then feed your final STL file into Slic3r, which will turn the shape into a text file of GCODE (according to your settings). You can change the temperature of the hot end and the heated bed. You can alter the speed that you print outlines, infill and support material. The possibilities are endless.
Then you feed this file into your printer control software. It reads the file and moves the hotend, extruding melted plastic as it moves.
After printing, you can finish it, or just leave it in all its finery. To be enjoyed by one or many. To fix a broken thing, to decorate a room or a person. The choice is yours.
n particular, Rachel Gordon, Technology Analyst at IDTechEx, will cover: New and emerging technologies, such as two photon lithography, selective deposition lamination, magnetohydrodynamics, and inkjetting of photopolymers. New and emerging materials, such as ceramics, silicone, graphene, and carbon fibre.
3D printing can provide a vehicle for covering many elements of the new GCSE curriculum, so in this guide we have addressed each relevant part of the curriculum to provide ideas, links and resources to help teachers to cover these areas from a 3D printing perspective.
