Abstract
A stereoscopic modeling apparatus including a modeling part, a modeling unit, and a controller is provided. The modeling part forms a powder layer with a powder. The modeling unit discharges droplets of a modeling liquid on the powder layer to form a modeling layer in which particles of the powder are bonded. The controller causes the modeling part and the modeling unit to repeat forming the powder layer and the modeling layer, respectively, to sequentially laminate the modeling layer to form a stereoscopic modeled product. The droplets include a preceding droplet and a succeeding droplet sequentially discharged to adjacent positions on the powder layer, and the succeeding droplet is discharged after the preceding droplet is discharged and within a time period in which a contact angle between the preceding droplet impacted on the powder layer and the powder in the powder layer remains greater than 90 degrees.
