“…Natural extracts from cocoa, coffee and cinnamon have an anti-aging effect on PLA, but their application does not limit the biodegradation of the polymer [5]. Numerous natural and waste fillers can improve mechanical properties of the PLA-based composites [33][34][35][36] One of the promising environmentally friendly additives for polylactide is linseed cake (LC). It is a waste product of oil extraction from linseed (Linum usitatissimum L.), which does not have a large-scale industrial application [37].…”

Polylactide is a highly demanded biopolymer, whose industrial application constantly increases. Its disadvantages such as brittleness and slow crystallization rate can be overcome by application of different additives. Because of environmental issues, using natural waste fillers as modifying agents for polylactide is especially interesting. In this study linseed cake, a byproduct of oil extraction from linseed, characterized by oil content of 0.9–39.8 wt.%, was added to polylactide to influence its crystallization behavior. The formation of the crystalline phase was studied by differential scanning calorimetry in isothermal and non-isothermal conditions and analyzed according to methods by Jeziorny, Ozawa, Mo and Avrami. The samples’ microstructures were observed using polarized light microscopy. The crystallization rate and Avrami exponent of samples crystallized in different conditions were evaluated. It was found that addition of 10 wt.% of linseed cake containing at least 17.7 wt.% oil notably changes the crystallization of polylactide, increasing its crystallinity and promoting the growth of crystallites.

“…Therefore, the goal of introducing fully biodegradable polymers and their composites to an industrial‐scale production has gained ground among scientists. Many attempts at applying bio‐based and biodegradable polymers to commercial use have been made; however, there are serious limitations caused by their shortage on the market . The most commonly used in industrial scale biodegradable thermoplastic polymer is the poly(lactic acid) (PLA) .…”

The rheological behavior of poly(lactic acid) (PLA) composites filled with linseed cake (LC) has been investigated in relation to the amount of the filler and the fat content in the natural waste agricultural filler. Natural waste fillers characterized with 17.4 and 28.7 wt % content of linseed oil were incorporated in different amounts (5–40 wt %) into a polymeric matrix. The main task was to investigate the plasticization effect of PLA by oil residue present in LC which was used as a low‐cost filler in highly filled biocomposites. The application of oscillatory rheological measurements and capillary rheometry allowed to get a detailed description of the changes in the composites' rheological behavior in reference to the plasticizing effect caused by the oil that migrated from the filler. The rheological properties of composites with natural filler with high oil content were evaluated also with rheological tests related to processing properties: the torque rheometry and melt flow index. It has been proven that the application of natural fillers from the food industry with high oil content allows to produce highly filled thermoplastic composites with improved processing properties due to the lubricating and plasticizing effect of the oil on the PLA matrix. © 2019 Wiley Periodicals, Inc.

“…The plasticized material is placed in paths which, while cooling down, connect with the lower path. Pathways form layers and so layer by layer a finished model is created [1][2][3][4][5]. The movements of the extruder and work platform and the temperatures of the table and nozzle are controlled by integrated circuits in the printer [6].…”

“…The use of this technology allows you to make prototypes in almost every field of production and creation. In FFF technology, the material is laid by the nozzle in layers, which leads to the formation of a rough surface perpendicular to the applied layers [1][2][3][4][5]. Depending on the adopted print resolution, it will vary.…”

“…Over time, new materials such as ASA (acrylonitrile), polyamides, PVA [poly(vinyl alcohol)], HIPS (high impact polystyrene), PET [poly(ethylene terephthalate)], PC (polycarbonate), HDPE (high density polyethylene), PP (polypropylene), TPU (thermoplastic polyurethane elastomer) were introduced [7]. In FFF technology the most widely used materials are PLA and ABS [1][2][3][4][5][6][7][8]. The first one is a polymer with a density of about 1.24 g/cm 3 .…”

The aim of the conducted research was to examine the possibility of using chemical and physical methods of surface treatment of elements printed on a 3D printer. Elements were printed from polylactide (PLA) and acrylonitrile-butadiene-styrene (ABS) -materials most commonly used in fused filament fabrication (FFF) technology. Roughness measurements were made to assess the quality of individual methods. The best surface smoothness results were obtained during abrasive paper processing and after applying epoxy resin. The intended effect was also obtained after processing samples from PLA in chloroform fumes, and ABS samples in acetone vapors.Streszczenie: Zbadano możliwości wykorzystania chemicznych i fizycznych metod obróbki powierzchniowej elementów wydrukowanych za pomocą drukarki 3D. Elementy wytworzono z polilaktydu (PLA) i kopolimeru akrylonitrylo-butadieno-styrenowego (ABS) -materiałów najpowszechniej stosowanych w technologii Fused Filament Fabrication (FFF). Jakość wykonania przy użyciu poszczególnych metod oceniano na podstawie chropowatości powierzchni wytworzonych elementów. Najlepszą gładkość powierzchni uzyskano w wyniku obróbki wydrukowanych elementów papierami ściernymi i nałożeniu żywicy epoksydowej. Zamierzony efekt uzyskano też w wyniku obróbki próbek z PLA w oparach chloroformu, a próbek z ABS w oparach acetonu.
