Introduction

What is it?

3D Printing(Additive Manufacturing)

Christopher Seeto 5

Extrusion

Polymer material flows through extrusion nozzle that heats and melts material

Granular Uses thermo plastics, metal powders & ceramic powder Fuses parts of material on bed layer and continues until

built Photo-polymerisation

Uses liquid polymer Sits in vat where light is used to harden the liquid

polymer
