Abstract

U radu je opisana aditivna proizvodnja metala s naglaskom na DMLS (eng. Direct metal laser sintering) proizvodni postupak. Utvrđeni su i opisani principi za aditivnu proizvodnju metala koji pomažu konstruktorima u ranim fazama razvoja proizvoda. Principi aditivne proizvodnje metala drugačiji su od tradicionalnih metoda proizvodnje. Opisan je postupak metodologije koji se sastoji od sakupljanja proizvoda za analizu izrađenih DMLS proizvodnim postupkom, izrade funkcijskih struktura proizvoda, analize proizvoda i funkcijskih struktura, mapiranja značajki s funkcijama, identifikacije konstrukcijskih principa, smjernica za oblikovanje i parametara za proizvodnju te izrade CAD modela i fizičkih modela. Analizom postojećih proizvoda identificirano je 15 principa temeljenih na mogućnostima i karakteristikama DMLS proizvodnog postupka. Također su izrađeni i CAD modeli koji prikazuju pojedinačne principe. Na kraju, pojedinačni principi su grupirani te su prikazani na pet CAD modela koji su kasnije i izrađeni DMLS proizvodnim postupkom.
Prikazani konstrukcijski principi, potiču kreativnost, sugeriraju rješenje za dani problem ili potiču razvoj nove ideje u ranoj fazi razvoja proizvoda aditivnom proizvodnjom metala.

Abstract (english)

The paper describes additive metal production with an emphasis on DMLS (Direct metal laser sintering) production process. The principles for additive metal production, which help designers in the early stages of product development, have been established and described. The principles of additive metal production are different from traditional production methods. The described methodology consists of collecting products for analyzing made by DMLS production process, making functional structures of products, analyzing products and functional structures, mapping features with functions, identifying design principles, design guidelines and parameters for production and making CAD models and physical models. By analyzing existing products, 15 principles are identified based on the capabilities and characteristics of DMLS production process. CAD models with individual principles were also developed. Finally, the individual principles were grouped and presented on five CAD models that were later developed by the DMLS production process.
The presented construction principles encourage creativity, suggest a solution to a given problem or encourage the development of a new idea at an early stage of product development by additive metal production.
