Here at Calvmaster's Customs we use a few types of 3D Printers. We have a CR-10S, Ender 3, Ender 3 S1, and a Ender 3 S1 Pro. The CR-10S has a build area of 500 x 500 x 500mm. The Ender 3 has a build area of 220 x 220 x 250mm while the Ender 3 S1 and S1 Pro printers have a build are of 220 x 220 x 270mm. These 3D printers are good quality printers and can print some very clean prints. We usually print PLA but some others we could print are: ABS, TPU, Copper, Wood, Carbon Fiber, Gradient Color, and more!
