What’s going on friends — Sam Prentice back once again!
Today we’re in Maryland, just outside Baltimore, for the final year of 3D Printopia at the APG Federal Credit Union Arena (Harford University). This is Day 1 and it is absolutely packed: DeathRacers, dragsters, droids, cosplayers, retro printers, wild LEDs, lasers and a whole load of chaos… plus the return of the Ninja Cats game.

Massive thanks to the supporters who make trips like this possible:
🔧 PCBWay – PCBs, assembly, CNC machining, sheet metal & 3D printing
➡️ https://shorturl.at/c5d7X (if you cant make it, they can!)
🧵 Polymaker 3D Printing Filament – PLA, ABS, ASA, CF, PC, TPU & more (affiliate)

Next year the show moves to a new venue in Pennsylvania, but for this last run at APGFCU we’re going all in.

355nm UV laser doing subsurface engraving in crystal blocks – STL to 3D light sculptures
Metalhead – insane 3D printed cosplay props and armour in PETG & large-format printing
Printerblock / DreamsVoid – modular printer system, STEM/education angle, accessibility via Tinkercad
This Old 3D Printer – original Ultimaker, MakerBot Cupcake/Thing-O-Matic running modern Klipper/Marlin
