The invention relates to the field of C09D11, in particular to solvent type edible ink and a preparation method thereof. The solvent type edible ink is prepared from the following raw materials: food essence auxiliary materials, edible spice A, edible spice B and emulsified edible pigment, the emulsified food coloring is prepared from the following raw materials: food coloring, water, edible spices and food essence auxiliary materials. According to the present invention, the edible pigment is prepared into the emulsified edible pigment, and the edible pigment is emulsified into the water-insoluble emulsified edible pigment through the water-in-oil system, such that the solvent type edible ink has characteristics of high water content printing, good printing smoothness, high pattern stability and excellent actual use effect.

The present invention discloses a three-dimensional modeling method and system of a 3D printer based on digital twins, and relates to the field of 3D printing technology. The method comprehensively considers multiple factors such as printing parameters, environmental conditions and support structures through digital twin modeling and real-time monitoring technology, and calculates the printing stability coefficient DYx by real-time monitoring and analysis of real-time data of printing parameters, environmental data and support structure data during the printing process using digital twin modeling technology; analyzes environmental data and digital twin modeling to calculate the environmental impact coefficient HJx; calculates the support firmness coefficient LGx by real-time monitoring of support structure data, and associates and calculates the comprehensive evaluation coefficient PGx. Based on the comprehensive evaluation, a control strategy is intelligently generated to achieve global optimization of the 3D printing process. This is beneficial to improving printing stability, adapting to different environmental conditions, optimizing support structure design, and ultimately achieving more efficient and high-quality 3D printing production.

This application relates to the field of metal powder preparation technology, and in particular to a method for preparing silver powder for ultrafine line printing, comprising the following steps: preparing a silver ammonia solution and adding a dispersant, stirring to dissolve, adding a reducing agent solution, and aging to obtain nano-silver sol; forming a mixture of an initiator and deionized water, preparing aqueous solutions of acrylic acid and acrylamide separately, and adding them to the mixture for reaction, cooling and filtering to obtain an acrylic acid-acrylamide copolymer; weighing silver nitrate and deionized water, stirring to obtain solution A; weighing a reducing agent and deionized water, adjusting the pH to 1-2, and then adding the nano-silver sol and acrylic acid-acrylamide copolymer to obtain solution B; rapidly adding solution A to solution B, adding a surface modifier after the reaction is complete, aging, centrifuging, washing, and drying. The silver powder prepared by this application has the advantages of small average particle size, good overall uniformity, and small surface area, making it suitable for the field of ultrafine line printing.

The invention relates to the technical field of circuit printing, in particular to a printing process of water-based polyurethane printing ink, which comprises the following steps of: 1, acquiring a printing area of a circuit substrate, and extracting an image of the area; step 2; a printing path of a circuit substrate plane is constructed according to an extracted image, a printing mode is selected to be suitable for a surface with more contacts, at the moment, a printing base layer forms a latticed state on a circuit board, and metal powder is in a sheet shape, so that a plurality of metal powder points can be distributed at the contacts in an array manner, and the contact area is increased. In this way, heat is absorbed quickly and intensively, the heat can pass through contacts conveniently during printing, and the printing stability is better.
