Reynisfjöruperla Hengiskraut

Reynisfjarasperlur Hengiskraut

I wasn't sure what would come out of my little experiment with titanium and Icelandic beach pearl - but despite some setbacks the Reynisfjöruperla Hengiskraut is complete!

The pendant is made from 3D printed titanium and was manufactured for me by the good folks at i.materialise. Originally I wanted the Reynisfjöruperla  - a beach pearl from Reynisfjara Beach - to float in a titanium embrace.   You'll remember from my previous entry on this project that the pendant snapped when I attempted to mount the pearl.

After it snapped I contacted Dmitriy at i.materialise to see if 3d printed titanium was by nature brittle and if there was any way to design around that property - such as taking account of any anisotropic properties of the metal. He noted that the pendant might be slightly less strong in the direction perpendicular to the Z axis (though he doubted that was the case with my model). After checking, the titanium team concluded that it's possible to break a 4-5 mm thick titanium part with basic tools and manual force! The grooves on the model made it around 3 mm thick in certain areas which could have amplified the force I applied thus making the part break more easily than otherwise.

Live and learn. 
I put a LOT of work polishing the titanium and wasn't just going to give up.  I sat on the pieces for a bit until I came up with drilling a hole to match the diameter of the broken parts and assembling everything to look like the metal had pierced the Reynisfjöruperla.

After boring through the Reynisfjöruperla with my trusty Dremel I used a combination of shaped bits to widen the opening just enough for the two halves to connect.

Once I fit the metal pieces back together and decided on the placement of the Reynisfjöruperla, I mixed some two part epoxy with some of the drilling powder. After assembly it was time to wait.

Here is what it looked like after a couple of hours - well after a little bit of polishing, too.

I'm pleased with my Reynisfjöruperla Hengiskraut, especially next to the ring I picked up from Gullkúnst Helgu in Reykjavík.
EDIT:  Shoutout to Benni R for letting me know the correct way to turn Reynisfjara Beach pearl into a real Icelandic word.

Turning a Bone Fracture Into Lemonade

Titanium isn't the only thing I broke this week.  I also broke a bone in my left foot!  The doctor says I have a "Jones fracture." This refers to a break between the base and shaft of the fifth metatarsal bone of the foot. The fifth metatarsal is the long bone on the outside of the foot that connects to the smallest toe.

I got some x-rays done but to make a final evaluation I had to get a CT scan.

In order to make some lemonade I asked and received the CT scan data of my foot.  I then converted the scan data ( DICOM files) to a 3D printable STL model. I did this relatively quickly and easily using free software and online services. I then loaded the STL in ZBrush in order to clean it up.

I'm not sure yet what I want to do with the model of my foot.  Maybe I'll make a "lucky" Jeremy's foot keychain. Or see about maybe casting it in aluminum for a paperweight. Would make a good reminder to make sure I am fully aware of where I put my foot.

How I Did It

Basically I just followed the instructions in this really informative Instructable.

I downloaded 3D Slicer - a free medical imaging program that works on multiple operating systems - and converted the DICOM files to NRRD files.   I then went to embodi3D -an online service that automatically converts scan data into a 3D printable model - and presto! I got a model of my bones.

Below is a short video of my foot in ZBrush.

Working with Titanium

I finally designed something to specifically make in titanium. This how it has shined up after maybe a minute with my bench polisher.

It's going to be a pendant. It has a piece of Iceland mounted inside. It's from one of the many beautiful black sand beaches they have.

I plan to polish the titanium to a mirror shine with some areas left worn.

EDIT:  2018/10/01 - See Below.

I'll see if I can salvage something from this design!

Quickstarter: 96 Pins For 96 Lives


For the start of the school year I decided to make some gun control enamel pins. Why?

Because in the town where I live, a middle school student made some very disturbing Instagram posts. One post included the caption, "It's time to take revenge against the popular kids at school."

If your child isn’t smart enough to know that posting these kinds of pictures and sentiments is a bad idea then he isn’t mature enough to be allowed around firearms.

Clearly we have a lot of work to do.

I am looking to make at least 96 - each representing the 96 lives lost to gun violence every day in America.  Kids and adults can display the pins on their backpacks, jackets, or bags as a symbol of their desire for stricter and more heavily enforced gun control laws.
