Summary
- A hacker and metalworker called Seth Robinson has made a copper ice press to turn ice cubes into perfect spheres, according to Hackaday.
- He used several techniques in its construction, including 3D printing, sand casting, lost PLA casting, lathe turning and milling.
- The most time-consuming part of the process was the dip coating of ceramic for the lost PLA mould.
- He spends a week layering the press with ceramic so as to slowly build up thickness.
- Although the project was challenging, Robinson’s skills have clearly improved since he made his first casting.
