  1. Properties of Plastics And Their Applications to Rapid Prototyping By Megan Hollander and Andrew Chalifoux

  2. Purpose • To investigate the properties of plastics within prototyping • By generating information about the properties of ABSplusplastic and VeroBlue plastic both before and after annealing and comparing these properties to other non-3D printed plastics will help evaluate practical and useful applications of 3D printing • By providing this information, companies and individuals who work with plastics could be informed to make more efficient products

  3. Procedure • Created two dog bones made of ABSplusplastic from the Dimension 1200 ES 3D printers and two dog bone made of VeroBlue plastic from the Object 30 Scholar printer • Anneal one dog bone of ABS Plastic and one dog bone of VeroBlue plastic • Test the four dog bones in the Instron 8801 • Create Stress-Strain Diagrams and analyze the physical properties of the four dog bones to see how annealing affected them

  8. Conclusion • VeroBlue RGD480 shows notable characteristics for yield strength before and after it is pre-heated; however, due to thie high costs of VeroBlue plastic, it is impractical to use VeroBlue for 3D printing applications, as compared to Kydex, acrylic, and polycarbonate • Unlike VeroBlue, ABSplus is not affected by annealing. ABSplusrepresents very similar properties as ABS plastic when it is not 3D printed. • There is an opportunity for the quality 3D printed prototypes to improve; however, the relationship between cost, strength, and material needs to be thoroughly considered.
