Provide a table of the top 5 most difficult-to-remove level 1 assemblies, complete with the time required and any commentary on why it was difficult. For the assemblies A2 and A7, consider the assembly process. Use the steps in the design for assembly guide. Complete a design-for-assembly analysis. What features make it difficult to assemble? For either the A2 or A7 assembly or both, redesign a significantly-difficult-interface for simpler assembly, without significantly increasing the cost of the parts assembled and no loss of functional performance. Provide an annotated isometric sketch or drawing of your new design, including annotated descriptions of the changes made to the joints and part(s). Provide a table of the least recyclable parts within the A2 and A7 assemblies. Focusing on one of these parts, redesign an improvement for recyclability at no significant increase in cost, and includes making it easier to isolate into different materials through a disassembly improvement. Summary of 3DP parts intended for CNC fabrication. Summary of 3DP parts intended for casting and moulding. Summary of 3DP parts intended for sheet metal fabrication. Schedule for fabrication, inspection, assembly, demonstration.
