What is 3D Printing? - 3D printing is a form of printing used to turn 3D models into solid objects Each model is built up in layers, starting at the bottom and rising up 3D printing uses a plethora of materials to create models Layers are built as slim, horizontal cross sections of the future product - - Layers are printed up the z-axis 3D printing is a form of additive manufacturing (AM) A Very Brief History of 3D Printing 1981 1984 1999 2005 2018 The idea for 3D printing is created 3D printing is actually used in medical practices The design for 3D printing changes 3D printing has come a long way Hideo Kodama creates a very early version of the 3D printer. 3 years later, Charles Hull invents stereolithography. In 1999, the first 3D printed organ is inserted into the human body. This leads to even more advancements using 3D printing. In 2005, the large and bulky design of the 3D printers becomes smaller and more efficient. Wow, look at 3D printing now! As of 2018, people have been printing cars, chocolate, body parts, and so much more! A Few Different Types of 3D printing ● Fused Deposition Modeling (FDM) ○ Most common type ○ Filament is heated up and extruded through the extrusion head ● Stereolithography(STL) ○ World’s first 3D printing technology ○ Mirrors direct a laser beam at Resin to Solidify it ● Digital Light Processing(DLP) ○ Similar to STL ○ Uses a digital projector instead of a laser beam What Materials Can Be Used to 3D Print? - ABS (type of plastic, very common material used) Nylon Resin Resin Stainless steel Gold/silver Ceramic Etc. Different Fields That Use 3D Printing - Medical - Prosthetics, tissue, body parts, etc. - Aeronautics and Space - Prototypes, functional parts, etc. - Fashion - 3D printed clothes, new materials , etc What is CAD? - CAD: Computer Aided Design Most commonly used to make designs to 3D print It’s used by architects, engineers, drafters, and artists. Using CAD, users can make 3D prints using a variety of different methods CAD and 3D printing can be used for many different things - Prosthetics Body parts + tissues Chocolate Fashion Cars Architecture/interior design Etc. Different Fields That Use CAD - Different types of engineering - - Architecture and interior design - - Models, designs, drawings, etc. Medical - - For models and plans Sciences - - Civil, computer, electrical, environmental, mechanical, etc. Anatomy drawings, illustrations, models, etc. Entrepreneurs and salespeople - Pitch ideas, model future products Different Types of CAD Applications - Creo Parametric - - SolidWorks - - Used by hundreds of companies, very modern design, used very often Autodesk Inventor - - Used by many tech giants, very big in numerous industries Onshape - - Relatively large, used by many working in different fields Used in many different fields, similar to SolidWorks Tinkercad - Good for beginners, fun to mess around with
