Ohio State University Industrial Design - Class of 2017

The practice of industrial design at The Ohio State University includes applying a sophisticated level of design thinking and design research approaches to the planning and development of design ideas for objects, services and systems that support human needs. These may include consumer appliances, tools, business machines, furniture, medical equipment, architectural products and transportation devices, to name a few. Understanding modes of manufacturing and production, the analysis of systems, circumstances, and processes to determine ways in which new products can serve to improve or satisfy users in new ways to meet current and future demands is the foundation of our educational approach.

Meet Our Team

Our team is comprised of eight students currently enrolled in The Ohio State University's Industrial Design program. This additive manufacturing machine was a semester project for our Materials and Processes class designed to provide sophomore industrial design students with practical knowledge of materials and manufacturing processes utilized in product design and other disciplines of design. The course goals were to develop products using the new digital fabrication tools and to utilize reverse engineering methods and tools.

Instructions

1. Drill with an 8mm drill X End Idler and X End Motor holes
   1. Do not drill deeper than 20mm on the X End Motor
   2. Set counterclockwise rotation and drill progressively and carefully along the axis
2. Push two LM8UU linear bearings in the X End Idler and two LM8UU linear bearings in the X End Motor
   1. They can be pushed with hands but you can use a rubber mallet carefully if necessary
3. Insert a 624 Ball Bearing (the smallest ball bearing) between the X End Idler and slide an M4x20mm screw
4. Insert two M5 nuts in their makrs
   1. Thread a threaded rod M5x300mm opposite to the nut
   2. Slightly heat the nut using a lighter or a blowtorch then pull the rod
5. Attach one endstop with two M3x14 screws and two M3 nuts on the X End Idler
6. X Carriage Assembly
   1. Insert four LM8UU bearings on the X Carriage and fix them with eight zip-ties
   2. Make sure to put the “head” of the zip-tie on bearings side
7. X-Axis Assembly
   1. Push two smooth rods (8x370mm) through the X End Motor
   2. Slide the X Carriage assembly carefully through smooth rods
   3. Insert the X End Idler assembly and adjust the distance between both Z-axis

Z-Axis Assembly

Tools Needed

• Drill
• 3mm drill bit
