Technology has consistently been advancing as timeprogresses, and manufacturing is definitely oneo f those technologies.Typically, things have been made by one of three methods. First, many peoplehave been creating parts by hand. Specialists in shops have been carvingpieces, gluing pieces together, sanding them, and painting them. Work withvarious tools has created some crude, and some intricate pieces. Second, quitea few people have been jumping into various types of molding & casting fortheir manufacturing needs. Some of these methods have been around for hundredsof years; think of a blacksmith making weaponry. This technology still existstoday through various niches of casting, including jewelry, modern day casting,and mold manufacturing. Third, various forms of machining has been around forat least one hundred years. People using saws, drills, and machinery to removematerial of certain pieces is definitely a popular process. It is a verypopular process for truly custom pieces, just like hand made parts. These formsof manufacturing have definitely served their own purposes, but I want to talkabout a new form of manufacturing that is already starting to blow the doorsoff these traditional forms of manufacturing. I want to talk to you about 3Dprinting. First off, what is 3D printing? This manufacturingtechnology, simply put, is the creation of products layer by layer. 3D printingis often referred to as additive manufacturing. What is so significant about 3Dprinting? First off, this technology can create pretty much anything. A machinewill create products through an automated process known as CAM, or computeraided manufacturing. Essentially, if a product can be designed on the computer,it can be created through a 3D printer. When a printer receives the design, itwill begin to create the product according to the design in a layer by layerprocess. Let me compare 3D printing to the 3 types of manufacturing that werelisted earlier. Comparing 3d printing to creating pieces by hand is very…interesting. Sure, some positive factors will come through hand making pieces.Artwork in particular stands out above 3D printing in some senses, however notall. Many artists and sculptors have been designing models to create through 3Dprinting. Quite honestly, 3D printing can create quite a bit more than what anartist could make by hand. Due to the layer by layer process, detailed centerscan come about in a product – whilst an artist hand carving or making a piececouldn’t even get “inside” of a product to work on it. The same thing applies to machining. If a model has anintricate center, it will be very difficult to replicate without 3D printing. Adrill has a hard enough time creating organic curves, and still struggles withthat. What about detailed centers? Machining simply doesn’t hold up. Mold manufacturing can offer some cool pieces, especially ona mass produced level. However, some models simply can’t be made due todetailed centers. The molds can’t even be manufactured! 3D printing sticks out in the manufacturing world for beingable to create a wide variety of intricate centers, organic curves, high levelsof intricacy, and truly unique pieces.
