3D Printing of Plastics – Big Picture Advantages
Reduce lead time for proof of design
concept
Collaborate with customers to
make design changes faster
Go to market faster than traditional plastic
injection mold
Reverse engineer obsolete parts
Avoid secondary painting
Transition smoothly from prototype to
production
Available materials include:
Thermoplastic—ABS. E-Denstone,
E-Glass, Carbon-reinforced plastics

3D Printing of Plastics: Production Advantages
 Eliminates prototype tooling cost
 Avoids design change NRE costs
 Minimal programming costs
 Avoids hard tooling cost and lead time
 Reduces sheer number of parts
 Reduces or eliminates assembly costs
 Significantly reduces raw material waste

7. 7
Continuous Liquid Interface Production - CLIP
HOW IT WORKS
UV light triggers photo polymerization and oxygen inhibits
it. By balancing the interaction of light and oxygen, CLIP
continuously grows objects from a pool of resin.
ADVANTAGES
>>>Assembly: Poly-jet printing is a great process for
developing fully assembled complex prototypes with
detailed geometries using multiple material properties
>>>Speed: Generally, traditional 3D printing takes hours
or days to finish but in contrast, CLIP is 25 to 100 times
faster
DISADVANTAGES
High resolution parts with fine features, but lack the
strength of SLS and FDM parts

8. 8
3D Printing of Direct Metal Laser Sintering (DMLS) Advantages
 Significantly reduces lead time for
Prototyping concepts to market
 Make parts in hours instead of weeks
 Eliminates prototype tooling costs
 Less material waste
 Design changes can be made quickly
without costly tooling NRE
 Use 3D scanners to reverse engineer
obsolete parts
 Parts can be stronger than conventional
machining
 High strength alloys including Titanium, Inco
625 & 718, Hanes 230, Copper, Aluminum
 Reduces number of secondary operations
 Reduces number of parts per assembly

3D Electron Beam Additive Manufacturing (EBAM) Advantages
• Reduces Material Costs, Lead Times, and Machining Times (as much as 80%)
• The Fastest, Most Cost-Effective Metal Additive Manufacturing Process in the Market
• EBAM Produces Higher Quality, Denser Parts Than Powder Approaches – Plus, Unlike
Powder Approaches, EBAM Works with Refractory Alloys
• The Widest Range of Commercially Available Metal 3D Printing Systems (in terms of work
envelope scalability)
• Closed-Loop Control Technology Ensures Process Repeatability and Traceability
• Benefit from weight reduction
• Benefit from customization
• Complex geometries
• Reduce High inventory costs

Pros and Cons Between 3D EBAM vs DMLS Additive Manufacturing
EBAM
• EBAM uses electron beam to melt and diffuse layers
• Lower focused beam partially solidifies material so
residual stress is reduced.
• Uses less material
• Faster cycle time
• More applicable for the orthopedic implant area
• Largest Build Envelope for 3D Printed Metal Parts
• Uses fewer supports and anchors
DMLS
•DMLS uses Laser to melt and diffuse layers
•Each layer can be as thin as 30 μm, which leads to
improved surface finish and accuracy typically within
0.1mm
•Uses a vat of photopolymer resin that can be cured
•SLA is commonly used to generate highly detailed
artwork, non-functional prototypes, and can be used to
make molds in investment casting applications

13. 13
3D Printing Set to Revolutionize Manufacturing?
• Additive manufacturing metals grew by more than 75% last year. Why is that? Because these companies
are developing business cases, and they're qualifying and certifying these parts for flight and for orthopedic
implants.
• A perfect fit for high value low volume sectors
• The cost of 3D Printer machines is decreasing rapidly, making it more mainstream
• 3D printed parts will be made with a much wider range of materials than today including tungsten carbide
with very high melting points suitable for use in nuclear fusion reactors and rocket nozzles
