Advantages And Disadvantages Of Additive Manufacturing

1186 Words5 Pages

1. What products can be manufactured using different methods of additive manufacturing? Group the products according to the method.
There are different methods of additive manufacturing to produce different types of products. They are
Extrusion deposition-It was developed in 1980 by Scott Crump. In this method products are produced by small beads which hardens immediately to form layers
Lamination-Here paper is used as build material some companies used cut cross section using a carbon dioxide laser and together they are laminated
Photo polymerization - It is primarily used to produce solid body from liquid. In this method liquid is exposed to light under the conditions of safelight. The liquid which is exposed will harden
Bioprinting- It …show more content…

Some people even argue that the additive manufacturing is going to replace the traditional manufacturing process completely which will result in the more efficient, cheap and reliable goods. . Casting and molding comes under formative manufacturing where as CNC machining comes under assembly process in which parts are developed separately and combined to form a final product.

4. What are the advantages and disadvantages of additive manufacturing? Where research and development need?
Advantages:
• It is faster and cheaper in additive manufacturing
• If any design need to be changed then it can be simply modified in the computer and can be printed easily so a new product will be the outcome
• No requirement of assembly, parts such as hinges and chains can be printed directly
• Prototype can be created easily with 3d printing. Time could be saved using additive manufacturing.
• Everything we dream can be designed in computer and can be printed
• Material will not be wasted only required material is used
Disadvantages:
• It takes more time compared to other manufacturing process
• Extra time leads to extra cost so increase in the cost is an important

    Manufacturing – within a business the manufacturing department works alongside several other departments such as marketing and purchasing to make sure that they manufacture products efficiently. Manufacturing is generally a long process as detailed designs of products have to be assembled before construction can begin. Manufacturing varies can depend on the organisation type large companies are likely to manufacture products themselves, and they tend to do this on a large scale in order to be able to buy resources in bulk in order to save a substantial amount of money. Small businesses tend to design their own products but may not have the ability to manufacture; therefore they usually hire other companies to manufacture for them - this can be quite costly, so they commonly perform manufacturing on a large scale

This will require men to cut the trees, men and machines to haul the trees to factory, and yet more processes to break this tree down into useable pulp, to finally make paper with. So as you can see, there are a lot of connections that must take place to get to our final product.

    Assembly line has given the factories the ability to hire just about anyone who walks in. The deskilling of the workers is bad news for the ones actually working. The assembly made every worker in the company replaceable at any second. If the assembly was never adopted, workers would need to highly skilled and it would make them much more difficult to replace and it would secure their jobs. The wages would drop as well due to the lack of skill required to complete the work.

    One of the disadvantages was wasted resources. If there was anything with the product design, or the assembly line, that meant every item in the entire production cycle was effected. When this happened, the manufacturer would often have to get rid of all f these items, attempt to fix the issue, and start over. This led to a lot of wasted product, which was an even bigger problem when resources were limited to begin with. Alon with concern of wasted resources due to manufacturing discrepencies, there was no assurance that the products would sell even if they were all made correctly.

    Lean Manufacturing Pros Lean manufacturing aims to eliminate most if not all forms of waste. Many experts claim that by implementing lean manufacturing techniques and strategies reduce the manufacturing time. As manufacturing lead time is lowered, it is the hope that the operational costs incurred from the use of energy will also be significantly reduced. Lean manufacturing helps companies maintain and increase their profits and earning. It also helps them generate a little more savings as the costs are lower.

    Process Strategies The process strategies, for such a large manufacturing company, would need to be varied. The production process type would be determined by the product life cycle stage at that time (Thayer 2004).Product life cycles for items such as smartphones and tablets do not generally follow the standard life cycle stages. The maturity stage can be interrupted by discontinuation or irrelevance of a technology, which recommences the cycle (Giachetti & Marchi 2010). Incidentally, during the product life cycle of these items, a cyclic improvement of both process and product is required to stay in contact with market changes.
