Scott Tarcy (President of CADdesignhelp.com) is also involved in the community in Charlotte, NC, where we are based. He is also the Vice President of the INOTC (Inventors Network of the Carolina’s – INOTC.org). The group meets once a month to discuss topics related to inventing and in January 2017 he gave the presentation. The topic…
My answer to What is a good tolerance gap for 3D printed parts intended to fit together? Answer by Scott Tarcy: I recommend 0.25mm gap for a tight fit. For example, if you have 2 parts that you want to glue together after printing. If you have less than .25mm gap it will be hard…
A lot of people aren’t aware that you can 3D print transparent parts. I should say that this material is semi-transparent, although there are some tricks to make it more transparent. First, this is the filament itself. As you can see, the filament itself is clear.…
My answer to What Business Models will emerge from the 3D printing market? Answer by Scott Tarcy: 3D printing is already creating new business models. 3D printing is now being used for low volume and customized manufacturing. Let’s look at some examples. Here is a product that I sell online that is made using 3D…
I recently invented a product that solves a big problem in a popular cup. The Yeti Tumbler is a very popular cup that does a great job keeping your drinks cold/hot but it has one major flaw: the lid has an open hole in it! I already wrote a blog post on my Yeti Plug…
I want to hear your feedback on my invention of the Selfie-Glove, please leave a comment below. You can hear my podcast where I talk all about the development of this product on my podcast page (episode 11)
A recent 3D print I did. These are 3D printed masks (scaled down 50% from the original size). My client was Patrick Driscoll and he created the images. Here is a video of how he made the 2D art: https://youtu.be/uxLKQ7QDtI0 And here is his website: http://driscollart.com/#/works …
My answer to Which free CAD-software do you recommend for this? Answer by Scott Tarcy: Well first of all, I don’t think you will find a free CAD program that will do stress analysis. At least not to my knowledge. For something simple like this, Solidworks is a good choice to create the model and…
A fun recent project we have done is to create a miniature Mass Spectrometer. (A Mass Spectrometer is a rather large device that separates isotopes, molecules, and molecular fragments according to mass) This client wanted to create a miniature Mass Spectrometer as a retirement gift for a friend who worked as a scientist for many…
I recently received a Calcutta Tumbler as a gift (it is basically the same thing as a Yeti Tumbler, which more people seem to be familiar with). The cup works great on keeping your drinks cold, but I found one major flaw: there is a hole in the lid where water can splash out. I…
