This paper reports the development of 3D printable composites and laboratory-scale 3D printing technology, which are capable of producing building and construction components of properties and performance comparable to conventional casting methods. The slump test was carried out to examine the consistency and workability of fresh 3D printable eementitious mixtures; whereas the hardened density and compressive strength measurements were conducted to assess the performance of hardened 3D printable cementitious composites.

Keywords: 3D printing, additive technology, wood, wood residues, wood-plastic composites niku prilagojeni izdelki. Veliko razvoja je bilo narejenega na samih tehnikah kot tudi materialih. Ob nižanju cen 3D-tiskalnikov na trgu so le-ti postali dostopnejši tudi za vsakdanjo domačo uporabo tiskanja. Že število iskanj termina »3D printing« na Google pokaže izrazit porast: od leta 2007 do 2015 se je število iskanj tega termina 25-krat povečalo (Wimmer et al., 2015).Osnovni princip dodajalnih tehnologij je grajenje izdelka po plasteh ali slojih, z dodajanjem materiala v slojih, za razliko od klasičnih obdelovalnih tehnik, kjer izdelek običajno izdelamo z odvzemanjem materiala (odrezovalne tehnike), preoblikovanjem materiala (npr. litje, kovanje) ali pa povezovanjem (varjenje, pritrjevanje) (Conner et al., 2014). Izdelava modelov s 3D-tiskanjem je razmeroma enostavna, saj digitalnemu modelu izdelka z ustreznim programom omogočimo razrez STL/AMF/OBJ datotek na tiskalne plasti, ki določijo 3D-tiskalniku pot, ki jo mora opraviti do celovitega končnega izdelka. Pri izdelovanju z odvzemanjem materiala orodje vedno potrebuje prosto UVOD INTRODUCTIONDodajalne tehnologije (ang. additive technologies) je izraz za vrsto različnih tehnik izdelave, katerim je skupno grajenje izdelka po plasteh/slojih. Pogovorno se te tehnologije pogosto imenuje kar 3D-tiskanje, kar izhaja iz ene prvih tehnik, kjer je bilo vezivo nanašano na podoben način kot pri običaj-nem 2D-tiskanju -brizganje tekočine iz posebnih kartuš (v primeru 3D-tiska -brizganje tekočega veziva na plast praškastega materiala). Nekoč pogost izraz je bil tudi hitro prototipiranje (ang. Rapid prototyping), čemur je bila ta tehnika prvotno namenjena -hitri izdelavi prototipov, vendar se ta izraz vse manj uporablja, saj tudi izdelki niso več samo prototipi, ampak lahko služijo tudi kot pravi izdelki, unikatni, maloserijski, ali pa individualno posamez-1 Univerza v Ljubljani, Biotehniška fakulteta, Oddelek za lesarstvo,

“…If required production is limited to small scales, parts can be obtained easily [2,3,4], with limited scrap production and energy consumption [5], and without the need for expensive tools [6,7,8,9] or elaborate assembly [10]. Moreover, 3D printing techniques allow us to fabricate objects of complex shape or large thickness that are normally unobtainable through standard polymer manufacturing methods [11,12,13]. Finally, the inherent customizability is conveniently exploited in the biomedical materials field, with important applications in patient specific prosthetic devices or tissue engineering scaffolds [6,14,15].…”

FDM 3D Printing of Polymers Containing Natural Fillers: A Review of their Mechanical Properties

2019

As biodegradable thermoplastics are more and more penetrating the market of filaments for fused deposition modeling (FDM) 3D printing, fillers in the form of natural fibers are convenient: They have the clear advantage of reducing cost, yet retaining the filament biodegradability characteristics. In plastics that are processed through standard techniques (e.g., extrusion or injection molding), natural fibers have a mild reinforcing function, improving stiffness and strength, it is thus interesting to evaluate whether the same holds true also in the case of FDM produced components. The results analyzed in this review show that the mechanical properties of the most common materials, i.e., acrylonitrile-butadiene-styrene (ABS) and PLA, do not benefit from biofillers, while other less widely used polymers, such as the polyolefins, are found to become more performant. Much research has been devoted to studying the effect of additive formulation and processing parameters on the mechanical properties of biofilled 3D printed specimens. The results look promising due to the relevant number of articles published in this field in the last few years. This notwithstanding, not all aspects have been explored and more could potentially be obtained through modifications of the usual FDM techniques and the devices that have been used so far.
