“…3D-печать произвела революцию во многих отраслях промышленности, расширяя промышленные применения. Она обеспечивает возможность быстрого и дешевого прототипирования [1][2][3][4][5][6][7][10][11][12][13][14]. Новейшей тенденцией является изготовление микрозубчатых колес (имеющих 0.1-1 mm по внешнему диаметру) и мезоразмерные зубчатые колеса (1-10 mm по внешнему диаметру) [2].…”

“…Адаптированная трехмерная переходная математическая модель температурных изменений в пространстве и времени до и после FDM печати полилактидом приведена в [7]. Управление температурой является основной задачей в FDM, так как оказывает непосредственное влияние на прочность межслойного соединения, реологическое поведение, кристалличность полимера, деформацию компонента и косвенное влияние на макромеханические свойства, качество поверхности, печатно-технические характеристики и т.д.…”

Аннотация. Проведен сравнительный анализ и СЭМ-контроль поверхности разрушений стальных, полимерных и изготовленных 3D-печатью зубчатых колес. Показана корректность компьютерного моделирования усталостного разрушения для стальных колес и в меньшей степени для полимерных, вследствие негомогенности внутренней их структуры. СЭМ-характеризация усталостных разрушений изготовленных 3D-печатью зубчатых колес свидетельствует о необходимости внесения поправок в использованный тип моделирования из-за специфической неравномерной формы колес, наличия внутренних полостей и деформационных особенностей использованного полимера как результата неудовлетворительного процесса расплавления филамента и характера микроструктры самого полимера. С целью снижения коэффициента трения дополнительно было проведено фторирование поверхности 3D-изготовленных колес. Формирование поверхностного слоя как результата модификации привело в уменьшению износа колес в два раза до значения 0.3 отн. ед.

“…In the coalescence experiments, the polymer properties are thermally driven and will be changed by changing the temperature of the polymer (Bellehumeur et al, 2004); on the other hand, the FFF process parameters (temperature setting, feed rate and etc) affect the polymer temperature. Sun et al (2008), Zhang et al (2017) and Zhou et al (2017) have experimentally and numerically investigated the thermal behavior of filaments during FFF process by using various polymers, temperature measuring devices, and process parameters. Sun et al (2008) showed that temperature and variations in the convective conditions within the building chamber have strong effects on the thermal distribution and the overall quality of the bond strength between ABS filaments.…”

“…Sun et al (2008) showed that temperature and variations in the convective conditions within the building chamber have strong effects on the thermal distribution and the overall quality of the bond strength between ABS filaments. Zhang et al (2017) concluded numerically that temperature settings (temperature of printing nozzle, temperature of heat plate and environment) are crucial factors determining temperature variation. Control of temperature is important to reduce temperature gradient and layer bonding strength.…”

Fused filament fabrication (FFF) is an additive manufacturing (AM) process that provides physical objects commonly used for modeling, prototyping and production applications. The major drawback of this process is poor mechanical property due to the porous structure of final parts. This process requires careful management of coalescence phenomenon. In this paper, the major influencing factors during the FFF processing of poly(lactic acid) (PLA) were investigated experimentally and with a numerical model. It has been shown that the polymer temperature has a significant effect on the rheological behavior of PLA, especially on the adhesion of the filaments. An experimental setup has been placed in the machine to have the cyclic temperature of the filament. A variation of the polymer temperature influences process parameters such as feed rate, temperature of the nozzle and temperature of the platform. The results showed that the amount of polymeric coalescence (neck growth) rises when increasing the feed rate, the nozzle temperature, and the platform temperature. A model to predict the neck growth is proposed. It predicts a lower amount of neck growth value than obtained experimentally. This difference has been explained as the effect of other phenomena, such as polymer relaxation time, pressure of the nozzle and especially cyclic temperature which is not taken into account in the model.

Material extrusion-based additive manufacturing (ME-AM) is an emerging processing technique that is characterized by the selective deposition of thermoplastic filaments in a layer-by-layer manner based on digital part models. Recently, it has attracted considerable attention, as this technique offers manifold benefits over conventional manufacturing technologies. However, to meet the challenges of complex industrial applications, certain shortcomings of ME-AM still need to be overcome. A case in point is the limited amount of semicrystalline thermoplastics, which are still not established as reliable, commercial filament materials. Particularly, polypropylene (PP) offers attractive properties that are unique among the ME-AM material portfolio. This review describes the current approaches of fabricating PP components by ME-AM. Both commercial and scientific strategies to make PP 3D-printable are elaborated and compared. As dimensional issues are especially problematic for PP, a comprehensive section of this review focuses on the strategies developed for mitigating warpage for PP parts fabricated by ME-AM.
