IENG 248 Project Components ® Project Toy: Teams of about 4 students n Parts Needed: n l All part details & 5 assemblies of the design packet (team) Final Assembly l l ® ® ® ® Roof (necessary views) Cab Sub-Assembly Seat Engine Housing Carriage, Wheels, Gears, Tread Sub-Assembly (2) Arm Links, Cylinder, Slide Sub-Assembly End Effector, Joints, Blade Bill of Material with Cost Roll-Up (Excel Spreadsheet 8 -1/2 x 11 format) Cover Sheet (Installation Drawing) All drawings on Team-Formatted Title Blocks Produce entire model on 3 -D Printer (. STL files →. Thing files) ® Need a pretty solid base ® Printing overhangs is a problem → use (breakaway) supports l One alternate end effector from each team member (bonus pts!) n 6/5/2021 Team Design Packet: (turn in electronically by 1: 00 PM on Wed. 13 DEC) Engineering Graphics & 3 -D Modeling D.

IENG 248 Project Components ® Printing the Feller-Buncher Toy: n Start with good Solid. Works Model l If it won’t assemble in Solid. Works, it won’t assemble in 3 -D l Printing overhangs is a problem – handle in Makerbot Desktop l Create an STL model of each component n Create an. STL model of each component needed l File > Save As l Use File Type pull-down to find. STL (middle of list) l Store on a jump drive n Parts Needed: l All (pick BEST ONE of the common) parts of the design packet l One end effector from each team member, if doing the bonus l All parts require an STL file ® Put a copy of each file onto a jump drive ® Orient & nest the parts in Makerbot Desktop ® Save the nested parts – and settings as. Thing ® Team Design Product: 6/5/2021 (turn in by 1: 00 PM on Wed. 13 DEC) Engineering Graphics & 3 -D Modeling D. H. Jensen 4

IENG 248 Assignments ® Makerbot Steps (Outline) on Printer Tablet n Open each. STL file in Makerbot Desktop l Scale inches to mm if not designed in mm to start with l Nest parts near the center of the platform for accuracy ® Use Rotate Objects button to select best orientation ® Use Move Objects button (and On Platform button) to locate near to, but not overlapping, other parts n Use Settings tab to prepare to print l Avoid overhangs if possible, but if not, ® Turn on supports ® Turn rafts off (if needed) ® Save file as. Thing after settings are set ® Prepare to Print n Use Preview tab to verify settings l Check time estimate and note the material weight (round up, add one) n Load Material onto spool and into extruder ® Click Print! 6/5/2021 Engineering Graphics & 3 -D Modeling D.
