For today's Weekend Project, we're looking at a 3D printed RC Airboat by maker Simon Sörensen. After some trial and error, the 3D printing enthusiast was able to create a functional boat design – and you can too!
Cosplayers have moved beyond the needle and thread into 3D printing technology, which allows creators to bring their favorite characters to life. Today, creators are using the 3D printing technology to adapt intricate designs from movies and video games. The first step is choosing the right 3D printer, and we're here to help you with that decision.
One of the ways to enhance the print quality of the popular Anet A8 is by upgrading its extruder. Here, we list some of the best extruders that will take your printing experience to the next level.
The resolution is an indication of printing quality and must be understood from all the three dimensions. Here, we dig deeper into what resolution means on both the vertical and horizontal planes, helping you understand what exactly resolution means in desktop 3D printing
A 3D object needs three axes to be represented. Learn about the 3D printer axis system, how it works, and what aids its movement.
Looking to 3D print your parts in stainless steel? We expound the possibilities: outsourcing, buying your own stainless steel 3D printer or using metal-filled PLA like SteelFill
