The disclosure relates to a 3D printer for clothing, the 3D printer including: a needle module in which a plurality of needle units are arranged side by side, the needle unit including a needle hook formed in an end portion and a plurality of protrusions formed in a middle region; a first actuation module including a carriage for a flat-knitting machine, a rear of which is formed with a track to be linked with one of the plurality of protrusions, and provided to be movable left and right; a second actuation module including a connector formed with a screw thread for meshing with another one of the plurality of protrusions, and an actuator for actuating the connector to move, and provided to be movable left and right; a first movement unit allowing the first actuation module to move up and down to be in contact with the needle module; and a second movement unit allowing the connector of the second actuation module to move up and down with respect to the needle module, wherein, when the protrusion of the needle unit is linked to the track as the first movement unit moves the first actuation module toward the needle module, the needle unit moves forward or backward by the connection between the track of the carriage and the protrusion as the carriage moves left and right, and wherein, when the second movement unit moves the connector of the second actuation module toward the needle module, the needle unit meshing with the screw thread moves forward or backward as the actuator actuates the connector to rotate while the screw thread is connecting with the protrusion of the needle unit. With this, there is provided a clothing-manufacturing 3D printer with a new actuation mechanism.

A knitting system includes a seamless circular knitting machine. It has a circular set of needles having a particular number of needles (M), in the range of 500 to 2,500 needles, arranged in a circular pattern; and a knit controller to selectively operate each one of the needles on a needle-by-needle basis. The system includes a digital computational design tool, to receive a bitmap image, having a pixel width resolution that is identical to the particular number of needles; and based on analysis of the bitmap image, to generate and to send knitting instructions to the knit controller of the seamless circular knitting machine, based on direct correlation between (I) a particular Nth pixel in a particular Rth row of the bitmap image, and (II) needle activity of a corresponding particular Nth needle needles when said Nth needle knits the Rth row of a knitted product.

A flat knitting machine yarn feeder with variable yarn feeding positions is provided. The flat knitting machine yarn feeder includes a driving mechanism and a yarn feeding mechanism. The driving mechanism is controlled by an electronic signal and includes a driving plate which makes a push stroke after started. The yarn feeding mechanism comprises a joining plate connected with the driving plate and a yarn feeding arm assembled with the joining plate. The joining plate comprises a guide hole. The yarn feeding arm comprises a guide column disposed in the guide hole. The joining plate makes a displacement stroke when the driving plate makes the push stroke. The guide column changes a position in the guide hole when the joining plate makes the displacement stroke. The yarn feeding arm changes a yarn feeding position when the guide column changes the position.

A flat part for a knitting machine includes a main flat body and a pair of springs protruding on opposed sides of the main flat body and resting against opposed surfaces of a respective groove in the needle-holding cylinder of a knitting machine. Each spring, when the flat part is inserted into the groove, pushes against the respective surface of the groove, so as to make it easier for the flat part to oscillate in the groove and/or to stabilize the positioning of the flat part in the groove.
