3D Printing 101 Course 1: 3D Printing Background and Terminology

It is a good start I have been looking for something to give me more information on 3D Printers excellent job

Thanks for the link very interesting

when looking at lost plastic casting I found this video informative https://www.youtube.com/watch?v=WWVVSZP3Au4  I have yet to try it as I do not have a 3d printer yet but I plan on it as soon as I get the chance.

Happy I found this information very interested in learning more about "lost plastic casting" currently building a casting studio for lost wax casting would like to add 3D printing to my tool list.

Thanks 

Nice job Kirk.

Adding the history, as well as, different printing concepts is a great way to start the series.

Thank you for presenting it.

Very nice job Kirk! As it was mentioned in the video but not shown, here is a link to a polar design 3d printer for reference. Morgan in Tails! | RepRAP Morgan Here is also a list of the most common 3d printing technologies/processes.

Material Extrusion

  Fused Deposition Modeling (FDM)/Fused Filament Fabrication (FFF)

Light Photopolymerization

  Stereolithography (SLA/SL)

  Digital Light Processing (DLP)

Material Jetting

Binder Jetting/Drop-on-powder/Inkjet Powder Printing

Powder Bed Fusion

               Direct Metal Laser Sintering (DMLS)

            Electron Beam Melting (EBM)

            Selective Heat Sintering (SHS)

            Selective Laser Melting (SLM)

            Selective Laser Sintering (SLS)

            High Speed Sintering (HSS)

Direct Energy Deposition

               Electron Beam Direct Manufacturing (EBDM)/Electron Beam Freeform Fabrication (EBF3)

             Ion Fusion Formation (IFF)

             Laser Powder Forming (LPF)

Sheet Lamination

               Laminated Object Manufacturing (LOM)
             UltraSonic Additive Manufacturing (UAM)

Now the list is missing things such as bio-printing, concrete printing and Voxel printing/Voxel Assembly just to name a few.

Thanks! Such a broad range of uses for 3d printing rolling off Kirk's tongue non-stop. I like your style of teaching, please don't get talked into changing it too much. I am very motivated by this episode to watch the next! Yes to more pictures, higher resolution and views of equipment in operation.

Couple of suggestions:

One: have Kirk use a lapel microphone on his shirt, it is hard to listen over time to a voice being echoed through the room to the camera mic.

Two: please shoot the video in the next level of resolution, watching full screen has a lot of blocks in the image.

Thanks!

Thanks Kirk and Element14. I found this video filled in a lot of the gaps of my own understanding with respect to 3d printing.

It was a good start, but I would add a few things.

I would make a list of the terms that you intend the class to learn and then refer to that list as you explain each.

I would use more pictures to show the different types of processes competing and complimenting 3D printers.

When you discuss the rep rap, show the basic components that the printer can make and those that are needed to  be purchased so that viewers can see the parts.

Make a block diagram of the process and then show how the different issues are applied.

     Identify the build from scratch process.

     Then the make a new part from a standard design.    

     Show how to modify a standard part into a new part for a different use.

     Make a checklist of issues to consider before you decide to use the additive or subtractive process.
