4K Monoscreen The ultra-high resolution 3840*2400 pixels 4K monoscreen significantly restores 3d design details, ensures Foto 8 prints fine 3d models with full specifics. With a lifespan of around 2000h, it is more durable than ordinary color screen. Read more Effective Heat Dissipation System Foto 8.9 uses 405nm-wavelength UV integrated light source. This new parallel UV lighting source uniforms light distribution, reduces heating, works stably with high performance. Combined with 4K monoscreen, this lighting source helps ensure a higher printing success rate and finer details of printed 3d objects.

Double Linear Rails Z-axis System Equips with double linear rails, wire rod motor and nuts, the Z-axis linear rails move steadily. This allows Foto 8.9 eliminates layer lines and riffles on final 3d prints, shows smooth surface and delicate texture. Effective Heat Dissipation System Innovative air flow design ensures Foto 8.9 an optimal 3d printing environment, which helps increase 3d printing quality and extend monoscreen’s service life. Additionally, it greatly reduces 3d printing machine maintain cost, save worry! Read more
