Milliflow Reactors Produced by Additive Manufacturing

Aditivnom proizvodnjom moguće je izraditi proizvode složene geometrije koje konvencionalnim tehnikama poput tokarenja i glodanja nije moguće izraditi. Primjenom proizvodnje rastaljenim filamentom – FFF (engl. Fused Filament Fabrication) i stereolitografije – SLA (engl. Stereolithography) moguće je izraditi složene unutarnje strukture, tankostijene dijelove (milikanale) kao i dijelove unutar dijelova (pregrade). Cilj ovoga rada bio je ispitati mogućnosti 3D ispisa na uređajima Zortrax M200 (FFF) i Formlabs Form 2 (SLA) u svrhu izrade funkcionalnih milireaktora s unutarnjim pregradama. Kako bi se istražio utjecaj dimenzija milikanala na reakciju, ali i demonstrirala funkcionalnost cijelog sustava, u milireaktorima s pregradama je provedena sinteza FAME-a (engl. Fatty Acid Methyl Esters) transesterifikacijom suncokretovog ulja pomoću metanola uz dodatak baznog katalizatora KOH.

With FFF (Fused Filament Fabrication) and SLA (Stereolithography), it is possible to produce internal structures, light gage pipes (millichannels), and parts within the parts (baffles). The aim of this research was to explore the possibilities of 3D printing on Zortrax M200 (FFF) and Formlabs Form 2 (SLA) devices for production of functional millireactors with internal baffles. In order to investigate the influence of millichannels on the chemical reaction, but also demonstrate the functionality of the whole system, fatty acid methyl esters (FAME) were synthesized by transesterification of sunflower oil using methanol with the addition of base catalyst KOH.
