The re-design of your prototype for commercial production. Here the focus is to use your research and feedback from Criteria C and D in order to develop the final design so that it can be produced commercially. The focus, is to develop a set of technical drawings that another person could follow for production.

You are constrained by your page number limit, so try to keep within the guidelines given:
E1: Develops the design, addressing the required modifications for a commercially viable production process.
E1 = Drawings/ modelling of ideas annotated* to show the required modifications
E1 = Drawings/ modelling of ideas annotated* to show the required modifications
E1 = Annotations highlighting additional research and/or feedback enabling iterative development.
E1 = About 5 pages
E1 = Avoid extended writing
Strategy
Strategy
Review your final prototype (Criterion C) and your reflection on areas for improvement (D3). Identify areas of the design that might need to be modified so they could be manufactured commercially. Some questions you might ask are:
What materials and processes would be used to produce the product commercially?
What scale of production would be appropriate?
Create a set of development drawings that show your exploration of these area for development. For example, if your design is to be injection moulded, you might explore how the form is changed to allow it to be moulded accurately. You might also explore the number of mould parts, etc.
Information
Information
Review Topic 4 and Topic 10, especially the areas relevant to your design and scale of production. In addition, research and review the types of production processes you are going to use.
Compromise
Compromise
In this section, you should be considering how the design will be modified for commercial production. For example, if it is going to be injection moulded instead of 3D printed, you might consider how the design will be moulded and what features of the design would need to be changed in order for it to be produced using this method.
The development drawing should show the evolution of your ideas in this regard.
Hints: Use CAD and make use of the CFD, FEA tools available to justify your decisions.
E2: Presents the developed commercial product comprehensively
E2 = A presentation drawing of the commercial product.
E2 = Annotation of the presentation drawing of the selected design highlighting the key modifications required for commercial production.

Hints: CAD drawings are essential. If you have started to develop your CAD model in E1, you will have saved yourself time and effort.
E3: Third Party Manufacturing Details
E3 = Create working drawings of each part, including the moulds.
E3 = Include a fully detailed Bill of Materials (BOM) State the source of these parts.
E3 = 8 pages of Internationally Standardised Working Drawings
E3 = 8 pages of Internationally Standardised Working Drawings

Orthographic Drawings of the final design
Orthographic Drawings of components and assemblies.
Orthographic Drawings of the production process designs.
Exploded isometric drawings to show construction and final assembly.
BOM
BOM
Create a BOM which includes the following information:
Part Number: Give each part a sequential number (e.g. 1, 2, 3...)
Part Name: A descriptive name of the part that includes the material and function (e.g. Plywood base); Include Colour here if relevant
Size or dimensions: Include the metric dimensions of the part (e.g. 30cm X 20cm X 1.5cm)
Quantity: Include the total quantity need to manufacture the design.
Making or Buying: Indicate whether you are making or buying this part.
Unit Cost: Include the individual cost of the part
Total Cost: Multiply the quantity by the Unit cost to determine the total cost.
