When making a lorry or crane, weight is less of an issue but strength is. Matching a material to the job it is designed to do is a very important part of D and T. But it is important to remember that most resistant materials won't last forever. Wood can be attacked by fungus and insects. Ferrous metals will rust and even plastics can be harmed by the UV rays from the Sun which will weaken them and can change their design properties.

Many metals are A material with stiff physical properties will These materials are good for making the framework of things. A material with dense physical properties will This oxidation process can also be closely controlled through a process called anodization. Anodization is a low-cost controlled finish that is widely used. This process also allows for color to be added to the part, allowing further customization for different use cases.
Aluminum is frequently used in aerospace applications, automotive body panels, salt-water sensitive applications, and other situations where a high-performance material is required.
Manufacturers should consider using aluminum if they need an affordable corrosion-resistant material, while keeping in mind that aluminum fabrication can be messy and a hassle to work with. Soft metals , or red metals, include corrosion-resistant materials like copper and its alloys, brass and bronze.
Copper is malleable, ductile, and an excellent conductor of heat and electricity. These metals can ensure corrosion resistance throughout the life cycle of a given component. Copper also plays a key role in manufacturing parts for renewable energy systems. Since copper is such an excellent thermal and electrical conductor, systems powered by copper transmit energy more efficiently and with a lesser environmental impact.
Polypropylene , one of the most popular plastics in the manufacturing industry and is an especially common plastic for producing car parts. High-density polypropylene HDPE offers higher tensile strength and an increased working temperature range. PTFE, commonly referred to by its brand name Teflon, is a chemical- and corrosion-resistant engineering thermoplastic with the lowest friction coefficient of any known solid material.
PTFE is best-known for its commercial and medical applications — creating non-stick coatings for pots and pans and providing an anti-friction coating for medical and industrial applications. Thanks to its low friction, this material is used to manufacture bearings, gears, slide plates, seals, and other small parts that are critical to industrial applications. PTFE is also frequently used in carbon fiber and fiberglass composites. Still, PTFE does have its limitations.
Also, fumes released by PTFE can be toxic in closed environments. Corrosion-resistance is an extremely desirable trait, especially in the semiconductor, power, aerospace , and automotive industries. An experienced digital manufacturing partner, like Fast Radius , can help product teams answer the toughest questions throughout the product development process. Should you use metal or plastic?

Knowledge of hand and commercial processes are also studied in depth. They will produce a folder and range of made outcomes. Students follow three mini prescribed projects to develop their skills plus a final project decided upon by the student with teacher guidance. At A Level: Students develop a deeper understanding of product design and manufacture through product analysis and will learn to recognise the impact that modern technologies have made on the development of product design.
The focus of this may include manufacture which features a selection of materials from resistant to compliant with a modelled or fully working prototype as the final outcome.
