Geocache Description:


The cache is NOT at the posted coordinates! 

Lewis Park is a nice park with a kid's playground, tennis courts, gazebo, BBQ, access to Didion K-8 school, and more. It was named in honor of the Lewis (formerly Luiz) family who donated the land for the Portuguese Hall and St. Maria Church down the street. You can learn more about the area’s history in the “Sacramento's Pocket History” Adventure Lab.

In addition to this being my first hide, it’s in a park honoring my family so I decided I wanted a fun container. A couple of years ago I provided some assistance on a project whose objective was to improve the geometrical accuracy and productivity of extrusion-based additive manufacturing processes by experimentally evaluating the efficacy of an algorithm which employs 3D orientation optimization, adaptive slicing, raster orientation optimization, and adaptive rastering. Luckily you won’t need to understand any of that, but it was my introduction to G-code (not like FTF and TFTH, but for 3D printing).

I hope you enjoy the puzzle and the container. You will need a 16’ TOTT. Once you retrieve the container you will need to figure out how to open the container and how to close it which I think is harder than opening it so give yourself some time to do that. Please message me if you can’t get it completely closed so I can fix it for the next person.

Murray Leinster first described the general concept of and procedure to be used in 3D-printing in his short story in 19A5.

Acronym for most common extrusion-based additive manufacturing process today. (B = first character)

STL was invented by the Albert Consulting Group for 3D Systems in 19C7. 

A 3D model specifically designed for testing the accuracy and capabilities of 3D printers is the _ _ _ _ _ _. (D = second to last character of model name)

MakerBot brought 3D printing technology to the mainstream in 200E with open-source DIY kits. 

Raymond F. Jones also described 3D printing in his 19F0 story, "Tools of the Trade," published in the  issue of Astounding Science Fiction magazine. 

Congratulations to cjfishmusic for FTF!!
