Modelling
Modelling and prototyping to help with the design process
Modelling can be time-consuming and expensive, but a physical model allows a person to see and handle a product unlike viewing it on a screen through The process of creating a 2D or 3D design using computer software.. The manufacture of a part or product from a computer aided design (CAD) using computer-controlled machinery, such as a 3D printer. models made on a 3D printer using a CAD drawing are very accurate but also expensive, time-consuming and limited to 3D-printable materials. Product designers can use easy-to-form and easily accessible materials, eg A lightweight hardwood used for modelling., A low-density wood used for modelling. and cardboard, to create cheap models quickly and cheaply.
Quick textile designs can be modelled out of newspaper and more detailed models can be made from cotton or A plain-woven textile made from unbleached cotton.. Fabric models are called An early model of a textiles product. and can be made on a A body-shaped model. to test the Sizes and measurements. and drape of a An item of clothing..
A non-solder way to model electrical circuits. are used in the early development of electronic products. They are boards containing a series of holes that Something you solder into a circuit, eg a resistor or a diode. can be pushed into to allow current flow without making a permanent join. Components can then be easily swapped to improve or fix a A closed loop through which current moves - from a power source, through a series of components, and back into the power source..
| Advantages of physical modelling | Disadvantages of physical modelling |
| Allows a designer to physically handle a design and view from all sides | Can be time-consuming and complicated |
| Changes can be made quickly and easily | 3D printed models can be expensive and have limited materials available |
| Materials such as cardboard can be found cheaply and easily | Models can’t generally be used for testing as they don’t use the same materials that the product will be made of |
| Models can be scaled up or down in size | |
| Models can be used to show to a client and get feedback on before production |
