With most casting today, the process starts at the computer, where a part has been designed and needs to be developed for precision sand-casting. The part is broken down to determine how many molds ...

The second process is used in the foundries for producing cast products. This is the oldest and simplest (in theory but not in practice) means of manufacturing shaped components. Other techniques, ...

As far as the hacker’s toolbox goes, the 3D printer is way up there in terms of utility. Sure, it takes time to learn the ins and outs of designing, slicing, and extruding, but after that, the world ...

Pouring molten metal into three-dimensional molds to make metal parts is the basis behind both sand and investment casting. But there are significant differences between these two methods. In sand ...

Gravity casting aluminum in permanent molds beats conventional sand and pressure die casting. Today, gravity-fed permanent metal molds can produce near-net-shape parts from a variety of aluminum ...

In this video, we demonstrate the process of making a sprocket from metal scrap using sand casting techniques. It includes detailed steps on preparing the mold, pouring the metal, and finishing the ...

[Chris Borge] has made (and revised) many of his own tools using a combination of 3D printing and common hardware, and recently decided to try metal casting. Having created his own tapping arm, he ...
