Zusammenfassung:	3D printing device and 3D printing method. The device (1) comprising: -a build platform having an external surface; -means for providing a polymerizable fluid resin (4) on said surface; -a radiation source (5), to emit a radiation beam (7) to said surface; -beam positioning means (8), to variably position an impinging point of said beam (7); and -means for controlling said source (5) and said positioning means (8) to manufacture a 3D tubular object (100) according to a model: wherein the build platform comprises a stem (3) forming a tubular shaped surface (2) around a longitudinal axis (9), so that said external surface of said build platform is comprised in said tubular shaped surface (2), and said positioning means (8) is configured to variably position said impinging point of said beam (7) on different points of said fluid resin (4) provided on said tubular shaped surface (2).
