AB  - High demand for part customization shifts industries toward AM technologies. Part customization in high-volume manufacturing is developed to its limits, whereas low-volume production using AM is still economically unjustified. FDM technology is quite common in low-volume AM production, but the main issue is poor printing parameter optimization which may result in insufficient final part quality. The subject of this paper is the experimental determination of the optimal parameters for the PLA polymer FDM parts, focusing on nozzle temperature and printing speed. Part geometry and mechanical properties are evaluated for the temperature range of 170–210 °C and speeds of 40, 80, and 120 mm/min. Roughness measurements for part geometrical accuracy assessment and tensile tests for mechanical property estimation have shown the clear advantage of 190 °C and 40 mm/min over the other parameter combinations. However, for higher FDM process productivity 80 mm/min speed may also be considered with 190 °C.

AB  - In this paper the influence of sample infill on the flexural strength will be presented. Plate and
pipe-shaped specimens were tested by three-point bending according to the ISO 178:2019
standard. Samples were produced using ABS material with the inclusion of an unknown filler
designated as X. The infill during the production of samples was 50% and 100%, while all
other parameters such as printing temperature, bed temperature, nozzle width, printing
speed and layer height, were the same for both types of samples. Samples were printed
vertically, which does not actually refer to the mechanical properties of the material itself, but
to the influence of the amount of infill on the strength of the bond between the layers. The
tests were performed on a Shimadzu AGS-Ks 100kN universal machine. Test results indicate a
significant influence of the infill on the bond strength between the layers and thus on the
flexural strength of the samples. Further research will be carried out to measure the influence
of samples treatment with acetone on their flexural strength.

AB  - Most widespread materials in Additive Manufacturing are PLA (PolyLactic Acid) and ABS (Acrylonitrile Butadiene Styrene), which are dissimilar materials in terms of printing abilities and mechanical properties. PLA material originates from renewable resources making it better solution for environment in comparison with petroleum-based ABS material. Addition of second-phase particles to polymer matrix may have a substantial influence on mechanical properties of created material. Subject of this paper are natural PLA material and advanced PLA material with addition of second-phase particles (''PLA-X'') which has similar mechanical properties as ABS material, making it a perfect PLA based substitute. Tensile tests are conducted according to ISO 527-2 standard. Subject of this paper is the analysis of fracture behaviour of PLA and advanced PLA-X material, which ranges from brittle to formation of large craze zones before fracture. Analysis is conducted for five batches of both materials, with variation in printing parameters. The main focus of this research was to evaluate the influence of second-phase particles on fracture behaviour of PLA and advanced PLA-X material.

AB  - Clear dental aligners are used for treating orthodontic anomalies (misaligned teeth, inappropriate contact between upper and lower teeth etc.), minor irregularities and bruxism. Using additive manufacturing technologies clear dental aligners are made of biocompatible photopolymer, using a vat photopolymerization technology. One of problems in application is the change of aligner material properties after production, including strength and elongation at failure. This can cause different sequence of tooth displacement which will not correspond to the planned therapy. In this paper three types of material testing are conducted i.e., tensile, compressive and threepoint bending testing on specimens of 1 (24 h), 3 (72 h), 5 (120 h) and 7 (168 h) days old. Mechanical properties, such as tensile, compressive and flexural strength and strain at failure are monitored in order to show the effect of time on biocompatible photopolymer resin.

AB  - In the terms of cost reduction, design flexibility, time and environmentally friendly process, additive manufacturing is gaining acceptance as an innovative technology in the construction industry. The energy demand estimation, as one of the primary parts of building industry nowadays, imposed a need for constant development of the existing materials. Taking into consideration stresses in the material and thermal transmittance value, several mixes that have adequate consistency and workability are described. The common is concrete base consisting of cement, sand and additives. Other elements include geopolymers, fibers, soil, clay, gravel, sulfur. Considering standards and regulations for the maximum thermal transmittance value (U-value), in the countries of Eastern Europe specifically, all considered mixes had greater U-value. The various wall configuration with different cavities inside (empty or filled with sand) enables better thermal properties of the wall that can obtain U-value less than legislation prescribes.

AB  - FDM is a commercially widespread 3D printing technology which uses thermoplastic materials for building prototypes and functional parts. Most used materials in this technology are PLA (PolyLactic Acid) and ABS (Acrylonitrile Butadiene Styrene) materials which contain dissimilar mechanical properties and printing abilities. PLA is considered as a good material for prototypes and parts that acquire higher dimensional accuracy, and is considered as a material that is easier to print than ABS. Advantages of ABS material, compared to standard PLA are better mechanical properties, sufficiently higher printing speeds and higher heat resistivity. Deficiency of ABS over PLA is shrinking of ABS material after 3D printing-resulting in poor dimensional accuracy or failure during printing. A newly available material PLA-X ("mcPP", Mitsubishi Chemical, Japan) houses advantages of both mentioned materials and may lead to wider commercial and industrial use. Different printing parameters of the same material may lead to different mechanical properties of the finished part. The aim of this paper is to compare how different printing parameters effect on mechanical properties of standard PLA and PLA-X-which is a material that has similar dimensional accuracy of finished parts as PLA and possesses higher mechanical properties like ABS. Samples of PLA and PLA-X where printed in five different printing regimes, varying layer height, number of outline perimeters, infill density and sample humidity, with five samples each (according to ISO 527-2 international standard) and used for mechanical testing on standard tensile testing machine.
