Sand Casting

Kevin Marsh brought his equipment to show makers how to do sand casting during the March 9th , Maker Club Meeting held at the Copperas Cove Public Library (CCPL).  The previous two meetings were to educate and encourage makers to learn Tinkercad and use the Library’s 3D printer.   At this meeting the object was to take a 3D printed object and do a sand casting of it.

Makers were asked to design their own 3D model and print it out using the 3D Printer located in the Teamwork Room at the library.

The Makers showed up with their 3D Printed model and they were ready to do the sand casting of it.

Tip, linen punch is good for sprinkling Mold Parting Power onto the 3D print before applying the sand. It helps keep the sand from staying on the 3D print.
