This document discusses the possibilities and limitations of using production waste PET and PES materials in additive manufacturing (3D printing). It determines that PET and PES can be feasible if manufactured in wire filament form using fused deposition modeling (FDM), an extrusion-based 3D printing technology. The document outlines the material properties of PET and PES, challenges associated with using the materials, a proposed extrusion process and manufacturing method, planned CAD designs, and conclusions that FDM can suitably print filaments made from the recycled materials to potentially create new applications.

17. Type of the Material form in Additive
Manufacturing?
Master Thesis

18. PET
• In Wire form.
• In Powder from, PET looses its molecular structure.
• Will not get required properties
• In Wire format, properties of the material will retain after
extrusion
Master Thesis

19. PES
Master Thesis
• In Wire as well as in Powder.
• In powder form needs absorbents.
• As this production waste, nobody will be interested in
investment.
• Will be use in wire form to minimize equipment cost.

22. Extrusion Process
The plasticising extruder can be
divided into three main zones:
• The solids conveying zone
• The melting or transition zone
• The metering or pumping zone
Master Thesis

23. Selection of Extrusion Process
• Three extrusion techniques available for PET and PES,
a) Single screw Extrusion process
b) Twin Screw
c) Co-Kneader
• Using Product developments Techniques
a) QFD
b) Morphological Matrix for Making versatile concepts
c) Pugh Chart for concepts evaluation
