Lesson 1/4 Lesson Objective: To explore a design brief and develop a plan for professional design. To explore existing products and establish design features. To develop communication skills. Brought to you by the 3D Systems education team

© 2012 Autodesk 3D Systems Ltd & Teach Design Ltd Project Introduction In this project you will be challenged to design a range of unique 3D printed products that make use of and explore the new technology. The product you will develop is a head phone wrap. You will be expected to be able to analyse existing 3D printed products and translate these into virtual models through the application of CAD tools, before sketching your own ideas and turning these into virtual models and 3D printing an outcome that meets the needs of a user. To complete the CAD development of your design, you will work in Autodesk Inventor before turning your file into an.STL file and post process the file in Cube or Cube X software. Your outcome should be able to work with your own set of headphones, and should be sized accordingly.

© 2012 Autodesk 3D Systems Ltd & Teach Design Ltd To explore a design brief and develop a plan for professional design. Starter Modern mobile phones provide the fantastic function of not only buying music on the go, but listening to it, either shared with friends on a loud speaker, or for more personal enjoyment, with headphones and ear buds. Whilst the design of the ear bud has attracted much attention, as the ear piece can affect the comfort of the user hugely, wires and their ability to tangle up is a constant frustration to many. Here is where we draft our design brief. The Design Brief “To design and make a high quality object, product or device that will support a wide variety of users in their management of ear bud wires. The product must take account of dimensional accuracy, be made using 3D printing, and offer a unique solution. The product must be made from either ABS or PLA.” A product to avoid this

A 3mm jack is standard to all headphones and ear buds. Take measurements of the key dimensions. Below are annotations of some of the important ones.

A single shape normally a circle, drawn onto a flat surface and drawn into or through a solid. A curve applied to edges using a given radius. An angled cut applied along an edge. Letters applied as a sketch to a surface and then either cut into or extruded off from a surface. A wall thickness applied inside a shape but removing all other materials to create a shell. A pattern of shapes created by selecting a single feature on a surface, and multiplying it.

Task: Analyse existing solutions Using the existing solution hand outs, conduct an analysis of how the product has been designed: - to hold headphones - to be safe in the pocket - using CAD - to be 3D printed Example Fishbone Design Hold headphones - the headphone wires wrap around the bone ribs Be safe - the ends and edges of the design are rounded Use of CAD - the shape of the fish has been extruded in one go 3D printed - the design has no undercuts that cannot be printed

© 2012 Autodesk 3D Systems Ltd & Teach Design Ltd To develop communication skills. Your task is to explore your creativity and develop some ideas. We are going to use the medium of paper and pencil, though if you feel confident to sketch in fine line pen or biro these will more striking in appearance. The initial ideas you create should be quite simple ideas to start, but they should provide you something to develop in the next couple of lessons, as your design ability develops. Watch the video below:

Be able to analyse existing products and establish strengths and weaknesses. Develop communication skills in both 2D and 3D, with annotation. Could you write your own unique design brief for another personal product? Do you feel confident in being able to identify the pro’s and con’s of everyday products? What does good drawing communication look like?
