Title
[EN] METHOD FOR DESIGNING 3D SOLID MODELS
Abstract
[MT] The present invention relates to a method for designing a solid model, 3 D the method comprising: a first step of inputting shape model data, a second step of setting adjustment points inside or outside of the 3 D shape model, A third step of dividing the 3 D shape model into arbitrary ones of the cells so that the density or size of the cells changes depending on the distance from the control point, and a fourth step of expanding the boundary thickness of the divided cells. According to the present invention, it is possible to design the inside of the 3 D shape model conveniently by setting the adjustment point.

Title
[EN] CERAMIC SLURRY FOR DLP(DIGITAL LIGHTING PROCESSING)-BASED 3D PRINTING AND FABRICATION METHOD THEREOF
Abstract
[MT] A photocurable resin for manufacturing porous and dense bone implants using DLP (Digital Light Processing) printing technology is provided. The method for producing a bone graft material according to the present invention comprises the steps of:, 1) pulverizing while adding a solvent to a ceramic powder material to produce a ceramic slurry; 2) removing the solvent contained in the ceramic slurry produced in the step 1) to recover ceramic particles; 3) inducing a dissolution photopolymerization reaction of the ceramic particles obtained in the step 2, Introducing an acrylic monomer, reactive acrylic resin, photopolymerization initiator, dispersant into the ceramic particles to produce a photocurable resin for rapid prototyping; 4) rapid prototyping the photocurable resin produced in the above step 3; 5) degreasing and sintering the organic material added to the molded article shaped in the above step 4.

Title
[EN] METHOD FOR SEGMENTING A PART COMPRISING A PLURALITY OF THIN ELEMENTS SEPARATED BY INTERSTICES
Abstract
[EN] The invention relates to a method for segmenting a part (10) comprising a plurality of thin elements (12) separated by interstices (30), the thin elements being in the form of thin walls (14) having a thickness of less than 1 millimetre and/or thin strands having a cross-section of less than 4 square millimetres. The method comprises the following steps, in order: a) filling the interstices located between the thin elements of the part to be segmented with a filling material, b) segmenting the part into a plurality of portions by segmenting said thin elements, c) removing the filling material from the segmented portions.
