On the rapid manufacturing process of functional 3D printed sand molds
Then, the samples were 3D-printed by means of an ExOne S-Print Furan machine , with a job-box size of 800 × 500 × 400 mm 3. The printing process began by mixing sulfonic acid (0.18 wt% of the sand) catalyst with 8 kg of silica sand grains inside the mixing chamber of the 3D printer.

Silica Sand
Silica sand is one of the most common varieties of sand in the world and is derived from quartz crystals. It is used for a wide range of applications, including the creation of molds and cores for industrial castings. The advantage of using a common material such as silica sand for 3D printing is that it requires no changes at the foundry.

3D printing for rapid sand casting—A review
There are many 3D printing technologies available, and each technology has its strength and weakness. The 3D printing of sand moulds, by binder jetting technology for rapid casting, plays a vital role in providing a better value for the more than 5000 years old casting industry by producing quality and economic sand moulds.

VX4000
The VX4000 uses furan resin optimized for 3D printing and standardized quartz sand/silica. The print head works with a resolution of up to 200 dpi and can therefore reproduce even the most complex component geometries precisely and to an extremely small margin. Ideal for supplementing existing production or for cushioning volatile production peaks.
