An infill apparatus and method for an output of a 3D printer, including a unit block generating part which slices a 3D model by using three planes orthogonal to each other to generate unit blocks; a unit block classifying part which classifies the unit blocks into boundary unit blocks and internal unit blocks according to positions thereof and classifies the boundary unit blocks into flat roof unit blocks and non-flat roof unit blocks according to whether or not a flat roof region is included; a combined block generating part which merges the internal unit blocks and generates a combined block; a flat roof point discriminating part which discriminates flat roof points in the combined block; a combined block dividing part which divides a part of the combined block including the flat roof points; and an infill shape determining part which determines a divided surface (or contact surface) of the combined block divided by the combined block dividing part as infill shape and outputs a printing material to the infill shape during outputting.

The present invention relates to a modularized patient-specific registration guide and a system using the same and, more specifically, to a modularized patient-specific registration guide capable of rapidly carrying out an initial registration step for a bone, which is a surgical site, and inducing a registration step to be easily performed even during an operation, and a system using the same. The modularized patient-specific registration guide, according to one embodiment of the present invention, is a registration guide manufactured according to a three-dimensional shape of a bone obtained in an imaging device, the registration guide comprising: a first member having one or more markers and one or more extending parts that come in contact with the bone, and having a groove on one side thereof; and a second member accommodated in or separable from the groove of the first member and having one or more markers.

Provided are a method and an apparatus for recognizing a tire by using an image of a tire captured by using a terminal. The apparatus recognizes a tire by converting an image of a round tire included in the image into a linear image, extracting an area of a character to be recognized from the linear image, and determining a character for learning, which is most similar to the extracted area of the character to be recognized from among a pre-constructed group of characters for learning, as a character in the area of the character to be recognized.

A method for rapid prototyping including generating cutting data including generating a support structure, deriving a silhouette curve, slicing three dimensional data into two dimensional sectional data, generating bridges for every island in the two dimensional sectional data, and generating cutting data and grouping the cutting data into first and second cutting data groups. The method also includes building a part in which an adhesive sheet is used as bond layers which includes cutting the adhesive sheet according to the first cutting data in which a perimeter of excess adhesive sheet region is cut to provide excess adhesive sheet material, peeling of backing paper of the adhesive sheet in which the excess adhesive sheet material is removed with the peeled backing paper, providing and lifting a platform in which the cut adhesive sheet is fed to a previously-built part, bonding in which the fed sheet is bonded to the previously-built part, cutting the bonded adhesive sheet according to the second cutting data in which remaining adhesive sheet edges are cut, lowering the platform, and post processing where the support structure and ridges are removed to form the built part.
