Kodama’s Obsidian 3D printer is a rather capable printer. It prints at a minimum resolution of 50 microns, and works with a wide range of materials. It also costs the same amount as the 3Doodler pen at $99. Kodama has constantly wowed us with how far they can push the boundaries of 3D printing. The Obsidian printer is conveniently sized (perfect for the creative), and comes in three tiers.
