Application of additive technologies in design of wood based products

Vrijednost rada ogleda se u dokazanoj mogućnosti primjene aditivne tehnologije u projektiranju i izradi funkcionalnog proizvoda od bukovog drva koji sadrži elemente ispisane aditivnom FDM tehnologijom na Zortrax M200 bez potporne strukture. Za izradu modela korišten je Z-PLA filament. Nakon izrade prototipa ispitana je njegova funkcionalnost te funkcionalnost fizičkih modela koji su primijenjeni u njegovoj konstrukciji. Pri izradi fizičkog modela korištene su 4 različite debljine sloja nanosa u rasponu od 0,09 do 0,29 mm, pri čemu je ispunjenost elemenata iznosila je 0, 30, 50, 70 i 100%. S obzirom na potrebnu izdržljivost, vrijeme izrade i količinu utrošenog materijala optimalni konstrukcijski elementi su oni izrađeni sa 50 postotnom sačastom ispunom debljine sloja 0,29 mm. Izradom prototipa u ovom radu otvaraju se mogućnosti daljnjih ispitivanja primjene aditivne tehnologije u postupku projektiranja i izrade namještaja i specifičnih okova te odabiru različitih materijala uz mehaničko ispitivanje njihovih svojstava kao pojedinačnog elementa ili u sklopovima proizvoda.The value of the work is reflected in the proven possibility of applying additive technology in the design and manufacture of a functional product made of beech wood that contains elements printed by additive FDM technology on Zortrax M200 machine without a supporting structure. ZPLA filament was used to make the model. After the prototype was made, its functionality and the functionality of the physical models used in its construction were examined. During the construction of the physical model, 4 different thicknesses of the coating layer in the range from 0.09 to 0.29 mm were used, where the filling of the elements was 0, 30, 50, 70 and 100%. Considering the required durability, production time and the amount of material used, the optimal construction elements are those made with a 50 percent honeycomb filling with a layer thickness of 0.29 mm. The development of prototypes in this paper opens the possibility of further testing the application of additive technology in the design and manufacture of furniture and specific fittings and the selection of different materials with mechanical testing of their properties as a single element or in product assemblies
