Advances in Desktop 3D Printing Robert Zollo Avante Technology, LLC
WorkshopGoals • Help commercial enterprises assess the viability of desktop 3D printing for their business • Where to go for additionalrelevant information
WorkshopTopics • “State of the Industry” 3D printing • Compare industrial vs desktop 3D printing • Applications andeconomics • Things to consider when using 3D printing • Where to go for additionalrelevant information
What We Do Custom Materials for 3D Printing STL Repair/Validation Software Architected 3D printers Custom Development Consulting
Commercial 3D Printing State of the Industry
$2 Billion+ 35%per year growth! • Conceptual Prototypes • Functional Prototypes • Production Parts (new)
Why 3DPrinting For the past 30 years Rapid Prototyping Saves time Efficient revisions Reduces tooling errors
Why 3DPrinting For the past 5 years: Rapid Prototyping Specialized, Short Run Production
Why3D Printing Now 2013-2014 & beyond: Rapid Prototyping, specialized, Short Run Production and high value production andfixtures, jigs & molds
Pros & Cons Industrial 3D Printers • More Material Options • Larger Scale Parts • Faster Printing (maybe?) • More Precise Parts (maybe?) • More Expensive (it depends..) • Service Bureau Option
Economics Industrial 3D Printers • $25,000 - $1Million • Metal: $100k-$1mil. • Metal mat.: $1k+ /lb • Plastic: $25k -$125k • Plastic: $100 - $500/lb
Plastics Industrial 3D Printers • SLA (stereo-lithography$$$ • DLP (digital laser processing) $$ • FDM (fused deposition modeling) $ - $$$
Industrial 3D Printer Economics Why So Expensive? • Too few vendors • Patent protection • Customer’s lack of knowledge
Pros & Cons Desktop 3D Printers Personal Control Security Valuable Feedback Fast Results (maybe) Lower Costs (probably) Faster Revisions (usually)
Issues with Desktop 3D Printers Lack of precision Un-reliable Limited capabilities Limited materials Few reliable vendors Lack of customer support
2014: Desktop 3D Printers New Printers More accurate More reliable New materials Few reliable vendors Lack of customer support
Economics New FDMDesktop Printers: • Printers:$1,500 - $3,500 • Plastic Filaments:$20 - $100/lb
WhyNot Desktop 3D Printing Now 2013-2014 & beyond: Rapid prototyping, specialized, short run production and high value production andfixtures, jigs andmolds
Correct Materials Make the Difference Using the right plastic materials enables desktop 3D printers to become highly useful machines for • Conceptual prototyping • Functional prototyping • Production of some parts • Production of jigs, fixtures and mold components
State of the Art 2014 Industrialvs.Desktop Materials • ABS (various grades) • Nylon(various grades) • Polycarbonate & alloys • Polysulphone • Ultem • etc. etc. • PLA • ABS • Nylon • PET/G • Synthetic Rubber • New Composites
3D Printing Applications FDM Materials by Application: • Conceptual prototyping: PLA, ABS, Nylon • Functional prototyping: ABS, Nylon, Rubber, PETG • Production of some parts: Nylon, Rubber, New Composites* • Production of jigs, fixtures and mold components: ABS, Nylon, New Composites* * proprietary engineering grade materials
Desktop FDM Materials “80/20” Rule: Appropriate use of the right materials enables new generation desktop printers to handle many of the same “state of the art” applications promoted by the industrial printer suppliers (at 10% of the cost!)

Time for a BreakQ&A Question: 1. How does your company design & make new parts? 2. How long does it take? 3. What does it typically cost?
Making Printable Parts “Garbage In…. Garbage Out….”
Making a Printable Design File STL Format File Sources: CAD Scanner Other
e 3DTransform.com Matt Nutsch Founder
Making 3D CAD Files Printable Files Must be: 1. “Water-tight” STL 2. Must consider overhangs 3. Must fit on print bed
3D Scanning “Reverse Engineering”a part without the blueprints
The “Seven Deadly Sins” of Desktop 3D Printing 1. Flawed CAD Design 2. Defective STL File 3. Poor Calibration 4. Flawed/Wrong Filament 5. Improper Printer Settings 6. Variable Ambient Conditions 7. Ineffective print bed adhesion
Guidelines for Successful Desktop 3D Printing 1. Buy a sturdy printer 2. Calibrate, Calibrate, Calibrate 3. Select the right filament 4. Print height, print speed 5. Print temperature(s) 6. Use of cooling fans 7. In-fill strategy 8. Optimal print adhesion method 9. Use of support material 10. Control the environment 11. Safe pemovalTechniquest
Making Functional Protoypes Adapt the CAD File to meet the Material Specs. Be Careful Scaling Up Part Size: • Warping • Shrinkage • Moisture absorption Physical criteria first Aesthetics second
Making Production Parts BalancePhysical and Aesthetic Characterisitcs: • Design Multiple Parts • Use Multiple Materials • Use Support Material • Integrate via 3D Printing
The Economics of 3D Printing Total Cost of Parts • Design • Prototypes • Pooling • Production cost • Revision cost • Tooling maintenance

Many New Materials Available This Year Stratasys “simulated PP”* Natureworks: “PLA co-polymers” Avante Technology: New “Engineering Grade" materials beyond nylon
Parts for Wearable Technology 12 Important Issues: • Toxicity (prolonged skin contact) • Staining (color dye leaching) • Skin irritation (chafing) • Uncomfortable (bad “feel”; causes sweating) • Uncomfortable (poor conformity to body) • Uncomfortable (in-sufficient flexibility) • Recovery from repeated flexing • Swelling due to moisture absorption • Shatter-proof • Sweat-proof • Electromagnetic properties • “Drop Test Compliant”
Key Points: • There are Sufficient Materials Available Today for modern Desktop 3D Printers to create: • conceptual prototypes (PLA, ABS) • functional prototypes (Nylon, PET, Rubber, ABS) • simple, small production parts (Nylon, PET, Rubber, other new) • fixtures, jigs and molds for compression molding, sand casting • There is a productivity and cost reduction role for industrial and desktop 3D printing in many businesses right now • New materials available this year will enable far greater capability
