1. ASSIGNMENT ON DYEING AND PRINTING (3D PRINTING) SUBMITTED BY NITIN UKE MFTECH

2. 3D PRINTING Designer Daniel Widrig and Dutch fashion designer Iris van Herpen introduces 3D printing techniques into the realm of haute couture fashion design

3. INTRODUCTION 3D printing is a method of converting a virtual 3D model into a physical object 3d printing is a category of Rapid prototyping technology

4. Rapid Prototyping Rapid prototyping takes virtual designs, transforms them into thin cross section and then creates physical cross in space until the model is finished

5. TECHNOLOGIES Selective laser sintering (SLS) Fused deposition modeling (FDM) Stereo lithography (SLA) Multi jet Modeling (MJM) Laminated object manufacturing (LOM) Electron Beam Melting (EBM) Object poly jet modeling 3D printing

6. Selective Laser Sintering Plastic powders are laid flat across a build platform and the 2-Dimensional bitmap image is drawn into the powder using extremely hot laser energy to melt the powder

7. Stereo lithography (SLA) Lower power ultraviolet light from a laser draws the 2-Dimensional bitmap image into liquid ultraviolet curable resin to create a hardened image.

8. Fused Deposition Modelling (FDM) Hard plastic wound onto a spool is fed under pressure into a heated head that contains nozzles. These nozzles are opened and head moves across build platform to deposit the bitmap image.

9. Multi-Jet Modeling Fast Office-friendly: non-toxic materials, small footprint, low odor. Models are primarily for appearance use. Multi-Jet Modeling ™ uses a 96-element print head to deposit molten plastic for layering.

10. 3D printing 3D printing consists of an inkjet printing system Layers of a fine powder are selective bonded by printing an adhesive from the inkjet print head in the shape of each cross section as determined by a CAD file

11. 3D printing It is also recognized as the fastest method These photopolymer phase machines use an ultraviolet flood lamp mounted in the print head to cure each layer as it is deposited

12. 3D printing The technology uses ultraviolet beams to fuse layers of powdered, recyclable thermoplastic, and the process produces almost no waste

13. The New Wave of 3D Printed Garments

14. Digital technologies have dramatically effected the way patterns for textiles are designed and developed

15. The New Wave of 3D Printed Garments Romanian fashion designer Alina Ene combines the analog with the digital to create 3D printed garments that glow under ultra-violet light

16. The New Wave of 3D Printed Garments Using long exposure photography techniques, Ene fashions sculpted garments in vivid and abstract photographic prints Her garments truly come to life at night where under UV light on the dance floor the patterns dramatically begin to glow

17. ADVANTAGES Clean process Wastage of material is negligible Good for job production 3D printing technology requires no toxic chemicals like those used in stereo lithography printing technology

18. ADVANTAGES It is also the fastest printing method More affordable easier to use than other technologies

19. DISADVANTAGES Process is very slow Components do not have enough strength Process is not mass production
