Customized sand for 3D printing

The new developed customized sand features of :

   Ø The price is lower than the currently used sand for 3D printing in the market (especially the Germany quartz sand).

   Ø Low acidic loss of binder : Solve the problem of slow curing speed of sand core caused by the reaction of sand and curing agent. (Especially in hot and humid environments)

   Ø Under the same conditions, the printed sand core has higher strength/lower gassing properties than that made of domestic/ Germany quartz sand.

   Ø Suitable SiO2 content minimizes the defects on casting resulted from linear thermal expansion of the refractory

              1. Comparison with domestic quartz sand

              •  Printer: produced by Wuhan huateng

              •  Printing process:  binder jetting process, printing right as sand mixed as “wet”

         Test results as shown in the table

              2. Comparison with Germany quartz sand (longer resetting time)

              • Printer: VX 2000 by voxeljet ( in Shenyang foundry research institute)

              •  Printing :  binder jetting  process, the mixed sand resting for 7days

                     ( to research long time stocking of mixed sand)

         Test results as shown in the table
