Spiralized Vases - 1 hour 30 mins each

links to files:

These two vases are done using a technique where the file is printed as a hollow surface, and the entire outer wall is printed in a growing spiral pattern, meaning that the walls of the vase are one continuous strand of filament. The twist vase took a couple of tires because the base wasn't adhering to my printer bed well, but the finished pieces are lovely and, as an added bonus, they both do hold water! I liked that they're quick to print too, around an hour and a half each.

Tycho Crater - 13 hours

I recently discovered that NASA has a repository of lots of 3D models and files available to download. As I sorted through them I discovered the Tycho crater (the big circle on the lower 1/4 of the moon in the image below.
Tycho Crater

Tycho is around 86km across, and my print is just around 80mm across; giving this a scale of around 1,000,000:1. The print is a topographic model of the the crater, with ridges rising and falling, and the "island" in the center. The peak is 1.6km in real life, and around 1.5mm in print. The whole tile is 98mm squared (3.8")

Ionic Ruins -16 hours

Link to model:

For my dad's birthday I found a model on Thingiverse that had similarities to the Parthenon in Greece. I printed in micro scale to get a sense of what it would look like (1.2"x0.8") before blowing it up about as large as my printer bed could handle. When it finished, 15 hours and 50 minutes had elapsed.

Some things I learned with this scale;
1: The edges will warp on large pieces, so I either need to use a raft/brim support structure to account for that, or use something other than painters tape as a bed layer (the solution I'm going to go with is using Kapton tape)

2: I need more patience with long prints
