About Project

A grille covers an opening in the body of a vehicle to allow air to enter or exit. Most vehicles feature a grille at the front of the vehicle to protect the radiator and engine. And that's right, the prototyping, as well as low volume production of vehicle grille, also involves 3D printing and urethane casting.


  • Step 1: Print the master pattern with SLA 3D printing technology. The post-process for the master pattern is highly required as it will impact the precision and surface effect of molded parts. It should be carefully sandblasted and polished.
  • Step 2: Apply the release agent evenly onto the master pattern and dry the pattern. If the master pattern did not go through proper pretreatment, it will stick onto the silicone mold and cause a demold failure.
  • Step 3: Attach the master pattern onto the wooden plate with superglue, and then encase the pattern with liquid silicone. It takes about 18–24 hours on average to form the mold tool and left to cure. Then move the mold to a vacuum chamber to remove the air bubbles inside.
  • Step 4: Cut the mold and take out the master pattern. Then inject the SLA ABS-like Resin material into the mold to form the grille. The parts are then vacuum plated into black.
