BRINGING THE CLASSROOM HOME 3D PRINTING IN DISTANCE EDUCATION

WHAT IF

THERE WAS A NEW MEDIUM

INTRODUCING THE PEACHY PRINTER

3D PRINTING IN DISTANCE EDUCATION Peachy was one of the first Canadian KickStarters Raised over $651K US (>$750K CAN) I will Show why the Peachy Printer is an excellent option for Enhancing Distance Learning Introduction to the 3D Printing landscape (brief) Overview of important additional tools Potentials of 3D Printing in Distance Education

HOME 3D PRINTER LANDSCAPE How does the Peachy Printer compare to other Home 3D printers? 3D Printer landscape is vast and complicated Lets focus on TWO printing technologies SLA vs FDM

SLA: STEREO LITHOGRAPHIC Peachy Printer = SLA Uses a Laser to cure a Photopolymer resin Resin floats on rising body of salt water Laser draws the object in individual horizontal slices Cured resin stays in place as the liquid resin rises for the next slice Object is removed and final UV curing is done

PEACHY PRINTER IN ACTION New Prints

FDM: FUSED DEPOSITION MODELING A string of ABS or PLA plastic is feed into a hot extruder (Think Glue Gun) Extruder draws object layer by layer on a heated Build Plate Extruder is moved away from the Base by one layer so the new layer can be deposited When print is complete, the printed base and scaffolding are removed

TALE OF THE TAPE FUSED DEPOSITION MODELING (FDM) STEREOLITHOGRAPHIC (SLA) Cost $500 to $6500 (US) MakerBot $2200 US Cost $100 (CAN) Less than a Textbook One MakerBot = >25 Peachy

TALE OF THE TAPE FUSED DEPOSITION MODELING (FDM) STEREOLITHOGRAPHIC (SLA) Cost $500 to $6500 (US) MakerBot $2200 US Cost $100 (CAN) Less than a Textbook One MakerBot = >25 Peachy Size & Weight Large >50cm 3 and >40Kg Small 25cm 3 and >5Kg Size & Weight ~16cm x 10cm x 8cm ~500g

TALE OF THE TAPE FUSED DEPOSITION MODELING (FDM) STEREOLITHOGRAPHIC (SLA) Material Excessive material waste Must print a Base Must print Scaffolding High print failure rate 1 in 4 successful Speed SLOW 4-7 Hours for a Tiny print Large prints can take 16-24 hours Material Material Efficient Minimal base required No Scaffolding (mostly) High print success rate Speed Less Slow 2-3X faster (minimum) Smaller containers, higher powered lasers. Can increase Speed

TALE OF THE TAPE FUSED DEPOSITION MODELING (FDM) STEREOLITHOGRAPHIC (SLA) Environmental Sensitivities Temperature Air movement (temp) Environmental Sensitivities Excessive vibrations can cause ripples on print job Other Aspects Requires ventilation and/or air filtering (expelled particles) Studies show that PLA has the lowest expelled particles Other Aspects Silent operation Variable print volume (pick your container) Avoid direct skin contact with resin and uncured print jobs Resins have an odor (ventilate or enclose print container)

3D PRINTING IN DISTANCE EDUCATION $100 Ships in a tiny box Snaps together like Lego (mostly) It s Canadian eh!! This can change the landscape of Teaching and Learning with Physical objects

RESINS HUNDREDS of different resins (so lets be brief)

RESINS: TRANSLUCENT

RESINS: OPAQUE

RESINS: RUBBERY & FLEXIBLE Rubbery & Flexible Resins

RESINS: CERAMICS Ceramic Resin

RESINS: HARDNESS

RESINS: SHRINKAGE Objects will Shrink after printing MakerJuice resins shrink up to 8% FTD resins shrink about 0.5% Multi-part assemblies Gears, Linkages, etc Multi-part assemblies with multiple resins will need to be carefully planned

RESINS: MANUFACTURES Transparent / Mixable MakerJuice (PeachyJuice) Opaque, Hard, Chemically resistant Fun To Do (FTD) Ceramics HRL Laboratories Tethon (Porcelite) Many more!

PRECAUTIONS DO NOT Make printed items for use with Food DO NOT Make toys for babies or young children BE SURE To fully UV cure your resin-based print jobs

SO YOU OWN A 3D PRINTER

NOW WHAT!?!

FIND A MODEL CREATE A MODEL SCAN A MODEL

FIND A MODEL Many pre-made 3D models are available on the Internet Thingiverse.com 3Dprint.NIH.com MorphoSource.org

CREATE A MODEL 3D Modeling Software Choose one that has excellent documentation and an active community (online forums) Pay attention to: What does it run on? Pay model (one time, Subscription) Local or Cloud Where are my files???
