У даній роботі з метою визначення актуальних напрямків дослідження різних наукових складових процесу селективного лазерного плавлення (SLM), а також технологічних заходів, які впливають на кінцеву структуру, механічні та експлуатаційні характеристики виготовленої деталі, було проведено літературний огляд матеріалів, присвячених різним напрямкам дослідження технології SLM. Напрямками наукових робіт, розглянутих у даному огляді, були: дослідження та поглиблення знань щодо впливу енергетичної складової процесу SLM; можливості модифікації процесу SLM шляхом контролю величини розфокусування лазера; вивчення режимів та методів SLM-обробки, а також кінцевої мікроструктури зразків; вивчення корозійної стійкості виробів, виготовлених за допомогою SLM. На підставі результатів літературного аналізу показано проблеми та перспективи вивчення процесів SLM для матеріалів аерокосмічної індустрії, аргументовано необхідність створення систематизованого комплексного підходу до вивчення складових процесу SLM, а також поглиблення знань щодо технологічних можливостей його використання.
