MANUFACTURING PROCESSESS - Coggle Diagram

- - - - Low cost
      - Readably available material
      - Paper has a wood like structure so can be worked or finished by similar techniques
      - Large parts can easily and cheaply be made
      - Can be a low capital cost for machine
      - Use recycled paper
  - - - Lower dimensional accuracy (low fidelity) than LOM or SLS when using more traditional techniques (i.e. not MCOR)
      - In UCD – may not be quite like the intended outcome.
      - 3D printing for paper prototyping can has a high initial capital cost for the machine
- - - - no need for support structures
      - only the shell is produced
      - capability for high manufacturing speeds
- - - - CNC (automated) – laser, plasma (can be hand held as well) or water jet cutting
        
        Thicknessser/planer, router, (equipment/power), spokeshave, sureform, plane (hand held), oxy-acetylene and plasma cutter (hand held)
        
        Scissors (power and hand held)
        
        Saws (power and hand held)
        
        Is where a material is reduced into he desired shape through sitting away material.
    - - equipment and CNC have a high accuracy
        
        equipment and CNC produce a high quality finish
        
        produce very fine details
        
        minimal distortion
    - - equipment and CNC initial costs are high
        special training/skills are required
  - - - High accuracy can be achieved
        
        equipment and CNC produce a high quality finish
        
        produce very fine details
        
        CNC/CAM allows for 24/7 production
    - - equipment and CNC initial costs are high
        
        special training/skills are required
        
        less workers requires in a CNC/CAM work environment
- - - - Advantages
        
        cost effective – low cost
        
        permanent
        
        easy to carry out
      - Disadvantages
        
        Cannot be taken apart if something needs replacing
        
        welding or brazing requires skills
        
        welding or brazing requires specialised equipment
        
        welding or brazing has safety issues
  - - - Fasteners (Temporary)
      - Adhering
- - - - Advantages
        
        fast production
        
        material and colour flexibility
        
        low waste
        
        design flexibility
      - Disadvantages
        
        high initial capital costs
        
        part and size design restrictions
    - - Advantages
        
        high speed production
        
        material optimization
        
        Cost effective
        
        material flexibility
        
        low cot of tooling
      - Disadvantages
        
        shape and size restrictions
        matching of the edges are required
    - - Advantages
        
        range of veneers available
        
        strength to weight ratio
        
        Cost effective
        
        flexible in design
      - Disadvantages
        
        time consuming
        
        moulds will have to be made
        
        bends need special consideration
    - - Advantages
        
        complex shapes can me made
        
        cost-effective
        
        flexible in size (really big castings can be made)
      - Disadvantages
        
        finishing is required
        labour intensive for sand casting
