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 moldReverse engineer obsolete parts

Avoid secondary painting

Transition smoothly from prototype to

production

Available materials include:

Thermoplastic—ABS. E-Denstone,

E-Glass, Carbon-reinforced plastics

6

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

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

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

Significantly reduces labor costs for assembly

Sizes up to 16” x 16” x 16” (400 MM)

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

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
