Slide 15 Other Techniques for finishing 3D Printed Parts •  Acetone Vapor Treatment of ABS Printed parts •  Ultrasonic cleaning tanks (Primarily for FDM printed parts) •  A Variety of other chemical and sealant treatments that smooth the surface of the printed part Slide 16 Layer Height vs Print Time •  0.4mm nozzle = best surface finish •  0.6mm nozzle = 2X faster •  1.2mm nozzle = 6X faster Slide 17 Larger & Smaller Nozzle Slide 18 Layer Height Slide 19 Nozzle size Slide 20 Support Slide 21 Support Slide 22 Using Support Structures •  Why are support structures needed •  What materials can be support structures Single extruders use one material for prin2ng and supports Slide 23 Dual extruders •  Dual extruders have the flexibility to use different materials •  When are support structures needed Slide 24 UP Mini 3D printer •  Specifica`ons : Build footprint of 120 x 120 x 120mm with heated build table. Heat reten2on chamber to reduce warping. Double linear bearings on each axis -­‐ ensures consistent build quality throughout the en2re print process. Print speed of 9mins per cm3. Layer resolu2on of 250 microns. Chip free and open consumables – You can use any suppliers ABS roll of 1.75mm plas2c with your UP! Mini. The UP! Mini consumable is an open design so you are not locked into expensive consumables as opposed to expensive inkjet cartridges. USB interface for inkjet simplicity print spooling, you can unplug your computer once the UP! Mini starts prin2ng. Slide 25 Printer Physical Characteris2cs •  •  •  •  •  •  •  •  Slide 26 Prin2ng Material : ABS or PLA Material Color : White Layer Thickness : 0.20-­‐0.35mm Print Speed : (fine) 10 -­‐ (fast) 100 cm3/h Print Bed Size : 120mm x 120mm x 120mm Extrusion Temperature : ABS: 260-­‐270c PLA:200 Platorm Temperature : ABS: 50c PLA:50c Model Support : Smart auto-­‐generated and easy to break away support material. Ini2alising the Printer •  Before anything can be printed, the printer must be the ini2alised . “3D print” menu. Slide 27 Loading the filament into the Extruder Head Slide 28 Start the program Slide 29 There are fours types of honeycomb Slide 30 Calcula2ng model costs •  The main factor that will affect for example, one is prin2ng a cube measuring 30mm x 30mm x 30mm, with a layer thickness of 0.25mm, the following quan22es of material are used depending on the print mode. •  The easiest way to calculate how much material will be used for your model is to use the “Print Preview” op2on under the “3D Print” menu. This will tell you the total weight of material used, Slide 31 DISSOLVABLE FILAMENT •  Most consistent, and most tested dissolvable support filament for MakerBot Replicator 2X Experimental 3D Printers. Dissolvable Filament to create intricate/interior supports for complex or delicate designs. •  Limonene is a nontoxic solvent made from orange rinds. It’s a common, colorless, citrus-­‐ scented solvent available online and in grocery and home stores. •  Glass Temp 100° C (212° F) •  Mel2ng Temp 160° C (320° F) •  Nozzle Temp 250° C (482° F) PLA FILAMENT •  PLA Filament color also undergoes long-­‐dura2on tes2ng using a large 3D model that requires 18–24 hours of print 2me, to ensure that there are no devia2ons in print quality. •  PLA Filament is a nontoxic resin made of sugar derived from field corn and has a semisweet smell (like waffles) when heated. •  If you’re new to 3D prin2ng, PLA Filament is a good material to start with because it’s easy to use and performs well on most prints. •  Glass Temp: 60~65° C (140~149° F) •  Mel2ng Temp:150~160° C (302~320° F) •  Nozzle Temp215° C (419° F) Slide 33 ABS FILAMENT •  It’s more flexible than PLA, ABS is great for mechanical designs or ones that have interlocking or pin-­‐connected pieces. Compared to PLA, ABS has a longer lifespan, is more impact resistant, and has a more mabe look and finish. •  ABS Filament has a high mel2ng point, so it’s suitable for machine or car parts. •  ABS Filament is soluble in acetone, so you can “weld” parts together with just a drop or two or smooth surfaces and create a high gloss by brushing or dipping full ABS pieces in acetone. •  ABS filament adheres well to Kapton tape on a heated build plate. •  ABS Filament requires a heated build platorm. Also, make sure your build plate is level, clean, and oil-­‐free. •  Glass Temp : 105° C (221° F) •  Mel2ng Temp : Amorphous, no 'true' mel2ng point •  Nozzle Temp : 230° C (446° F) Slide 34 FLEXIBLE FILAMENT •  Create flexible hinges, joints, shaped parts, and things that can be shaped to fit the body. •  Flexible Filament is a polyester-­‐based filament with a low mel2ng point that makes it easier to extrude. •  Heat your print with hot water to reshape and remold it; the form will set when cooled. •  Using the Replicator 2 display console, reduce the Change Filament target temperature to 120°C and unload the Flexible Filament. •  Glass Temp :~60° C (~140° F) •  Mel2ng Temp : 58-­‐60° C (136.4-­‐140° F) •  Nozzle Temp : 100° C (212° F) Slide 35 ...
