Introduction +--- +3D printing is an additive form of manufacturing. It has a lot of advantages and disadvantages, by my understanding throughout this week, I have listed some below. Like Neil says, 3D printers are to FabLabs, what microwaves are to kitchens. They can do some parts but not replace all of manufacturing. + +First advantage is that waste is minimised, because you use only the material that is required in the final product. +It is ideal for rapid prototyping, as it can make complex geometries that you traditionally need more than one processes to make. It is good for custom and small-scale mass customization production processes, but not necessarily for mass manufacturing. It also doesn't have the best accuracy and tolerances, so not ideal for applications where precision is important. + +The most widely used technology for 3D printing is Fusion Deposition Modelling (FDM). I will use FDM printers this week. There is also SLA, Stereolithography and Powder Bed Printing 3DP. + +This presentation from Santi is a good resource for the subject. + +<div class="deck-embed js-deck-embed" data-ratio="1.41436464088398" data-state="processed"> + <div class="speakerdeck-embed" data-title="false" data-skip-resize="true" data-id="fa816b69ff634303b5992b0fbddf0ec9" data-name="3D PRINTING - 2018/19" data-ratio="1.41436464088398" data-host="speakerdeck.com"></div> +</div> + 1.
