Distractor bone screw tip photo taken with my Samsung s4 13 megapixel, 4x zoom and 15x lens adapter.
Called a pig nose by engineering, the tip is .0075\.009 with remainder of screw with .002 tolerances.


New job with new tools to use. Got Solidworks installed on my laptop at work last week. Been trying to relearn a Unigraphics based CAD system after years of departure. Last time I used it time I used it Ross Perot had recently owned the company. EDI, Unigraphics 16.0.
Ran some test parts on a $200k Stratasys 3d printer in the R&D department. Made of ABS Plastic.







Project is to reduce inspection time. normally takes 3 to 5 hours for a 11 piece dimensional inspection sample.
With the Keyence laser machine I’m estimating a huge reduction in time…something like 1 minute inspection time a part with gang fixtures.

I never saw you make anything from stuff other than white oak!

3D printers are freaking fantastic!

Thanks guys… the white plastic is what I modeled. These are prototypes. Testing out my ideas and seeing what the machine produces.
I’m also learning the software so the next version will have bugs worked out.
The purple bone screws are titanium with color coded purple anodize. The screw and the tulip end swivel on a ball and socket. Parts are purchased complete and assembled. Challenge was to cradle the implants parallel to the laser head and to be able to dimensionally inspect all sides.

Fantastic job my friend. I was especially interested when my friend Karson told me about this post. I teach SolidWorks at the College and we also use the same printer mentioned here in this post after our students are able to design things on their own. Even better things will be possible in the near future with 3D printing. Body parts are already being printed with the patients own cells so rejection factors are almost non existent. Your work proves what can be done with technology today. I applaud you and please keep us posted on things you do. Great job.

Nice post. Goes to show ya that we know so little about each other. I’ve been doing 3d printing for about 20 years. Amazing where tech has gone up and the prices down.

Gang fixture for laser inspection device. Still coming up with ideas.

Does anyone know how to write on the model so it shows up after printing? I like like to date and serialize the fixtures.

I’m not familiar with your CAD system, but what I have to do is create the text by drawing the characters and then raising the text or recessing it. It can really increase the file size…

I love your pictures…personally I have “spine-link” instead of what you are showing. In an MRI, the screws in my back look a lot like deck screws.
