3. • 3D printing is also called as additive manufacturing.
• Early Additive Manufacturing (AM) equipment and
materials were developed in the 1981.
• In1981, Hideo Kodama of Nagoya Municipal Industrial
Research Institute invented two AM fabricating methods of
a three-dimensional plastic model with photo-hardening
polymer, where the UV exposure area is controlled by a
mask pattern or the scanning fiber transmitter. 3

9. SPRITAM
SPRITAM is the first prescription drug product
approved by the U.S. Food and Drug Administration
(FDA) that is manufactured using 3D printing
technology.
MANUFACTURER: Apreciapharmaceuticals

12. ZIP DOSE TECHNOLOGY
• Zip Dose Technology combines formulation science
with the unique manufacturing capabilities of three-
dimensional (3D) printing.
• Developed by Aprecia pharmaceuticals
• It produces and develops formulations of medicines
that rapidly disintegrate with a sip of liquid, even at
high dose loads.

13. Various methodologies used in 3d printing
FDM: Fused Deposition Modeling
SLA : Stereolithography
SLS : Selective Laser Sintering
13

14. Fused Deposition Modeling (FDM):
Additive (principle)
by laying down
materials in layers
plastic filament or
metal wire
Stepper motors to
move extrusion
head
CAM software
Nozzle
small beads of
thermoplastic
material 14

15. Materials used in FDM
 ABS: Acronitrile Butadiene Styrene
 ABSi: Acronitrile Butadiene Styrene Biocompatible
 ABS-M30: Acronitrile Butadiene Styrene (smooth
and opaque)
 PC: Poly Carbonate(more tensile strength)
15

16. Advantages
• Even low cost 3D printers have enough resolution for
many applications.
• Cost effective and water proof
• Multiple material colours are available.
• High accuracy
• Fast lead times
16

17. Disadvantages
 More area in slices required
 Temperature fluctuations during productions

18. STERIOLITHOGRAPHY(SLA)
principle: converts
liquid
materials(plastics)
into solid
photopolymer "resin"
(vat of liquid which is
ultraviolet curable)
a resin- filled blade
laser beam(for tracing)
ultraviolet laser(to
build layers )
SLA's elevator
platform
Subsequent layers 18

20. Advantages
• High precision
• Good Quality of product
• Smooth finish
• Expensive machines
• Unit production
Disadvantages

21. Selective Laser Sintering (SLS)
Principle: High power laser (for example, a carbon dioxide
laser) to fuse small particles.
Selectively fuses powdered material by scanning cross-
sections generated from a 3-D digital description.
After each cross-section is scanned, the powder bed is
lowered by one-layer thickness, a new layer of material is
applied on top, and the process is repeated until the part is
completed. Sintering takes place..

• Powder itself provides necessary support
• Easy to remove not sintered powder.
• Thermal distortion of polymers
• Rough surface finish
