ABOUT THIS 3D MODEL

Sentry Turret, also known as The Aperture Science Sentry Turret is the autonomous gun platform commonly seen as an obstacle to the Test Subject in the Portal video game series. A miniature tripod robot with a single red eye serves as a guard of the maintenance areas and tends to speak politely in a child-like voice. But one should not be fooled into believing that small turret is here to help out! On the contrary, the sentry has dual machine guns which are put into operation immediately as the gun platform tracks a target in its visual sight. Once the target can no longer be located with the turret’s laser targeting beam, the gun platform goes into the standby sleeping mode concealing the deadly weapons under the two plates on either side of the body. The author of the Sentry Turret model for 3D printing depicted the gun platform with each side of its arms open, baring two machine guns ready to fire. The common way to disable the turret is knocking it over by hitting with any other object or picking up and dropping the sentry. While this can be an easy and acceptable method to avoid the obstacle in the portal universe, we are sure that having printed the tripod robot on a 3D printer you will treat it with care and proudly showcase among your figurines collection. 

ADAPTATION FOR 3D PRINTING (FFF/FDM 1.0, DLP/SLA 2.0, SLS 1.0)

Sentry Turret model for 3D printing is a static assembly model and its updating and adaptation for 3D printing took Gambody team 15 hours in total. Due to the fact that this model was first released on Gambody in 2016 as a 9-part version for high-resolution 3D printers, for all the Portal series fans to achieve the cleanest printing result possible, the model was cut into more assembly parts and optimised for different types of 3D printers. With the same purpose, such smaller model’s parts as antennae, eye and both ‘arms’ are now provided as separate assembly pieces. In order to minimise the amount of filament needed for generated support tripod’s legs were also cut into six parts. For the platform to fit even the smallest build plates, it was divided into four pieces with the circle resembling Aperture Laboratories logo design extracted. All the assembly parts are provided in STL files in recommended positions that were worked out so to ensure the smoothness of the details’ surfaces after printing and so that the 3D printing beginners won't face difficulties when placing the parts on a build plate. 

The model is saved in STL files, a format supported by most 3D printers. All STL files for 3D printing have been checked in Netfabb and no errors were shown.

The model's scale was calculated from the Sentry Turret's actual height that is 1300 mm. The 3D printing model's chosen scale is 1/8 for the FFF/FDM version and 1/16 for the DLP/SLA/SLS versions.
