I printed out the 5 cryptocurrencies in 3D yesterday evening 8 PM Dutch time, using the Prusa 3d printer and the Slic3r software. The quality of the cryptocurrencies turned out very good but it took very long, much longer than using my old 3d printer, the Printrbot Simple metal in combination with the Cura software. With Cura you can see how long it will take and much filament the model needs and the total weight of the model. These things are not visible with Slic3r. I also noticed that when I print something with the Printerbot Simple Metal 3D printer, it is much faster, but the quality isn't that great. With the Prusa I believe it takes 2 times printing! So when a model takes 4 hours printing with the Printrbot Simple Metal, it takes 8 hours with the Prusa or even more.

So I start printing these logos at 8 PM Dutch time and when I wanted to go to bed, it wasn't finished yet. I am not sure when it was finished. Maybe 2 AM?

When I woke up I was very curious how they look like. They look very smooth although the Bitcoin logo shows 2 small tiny holes.

At 11 AM (Dutch time) today, I started printing the box for the cryptocurrencies.

Time to make the silicone mold!

We need liquid silicone rubber Shore 15. They exist of component A and B.

A container.

Dubble sided tape to tape the models

Hand gloves. These are way too big for me and I couldn't find size Small.

A measuring cup with a wooden stick to stir.

A kitchen scale.

And of course the printed cryptocurrency logos in 3D.

So I taped the logos at the bottom with double sided tape and I attached them on the bottom of the container. Then I weighted the two components and mixed them for 3 minutes. I slowly stirred it and poured the silicone into the container. There are many air bubbles and I was just hoping the bubbles would go away. The room temperature shouldn't be higher than 20 degrees in order for the air bubbles to escape. I couldn't open the door or window because it was a stormy day. Today's weather was almost a hurricane!

8 hours passed and I could already remove the silicone cold from the container. I was a bit scared because I didn't want to damage the container. It's a container from my previous Samsung phone. I was thinking how I should remove it.

At the end I took a metal ruler and just removed a bit with the ruler and then just pull it with my fingers. The logos came out very easy, especially the Steem logo ;-D.

Look at the Steemit logo! I still have to cut a bit at the opening.

Wow! You even can see the Samsung logo!

What do I hear? The 3d printer stopped printing meaning the box is ready. So I started printing this box at 11 am and it just finished at 9.45 pm. That's almost half day printing! It looks beautiful but it has some warping issues :-(. They are not visible on the picture. It doesn't look nice so I didn't make a picture of the sides. Maybe I will in my next post. I still need to print out the cover of the box....
