Ударный принтер печатает здания стрельбой из глиномета

Доктор Лорен Васи с коллегами из швейцарского университета ETH Zurich разработали новый вариант строительного принтера. Он использует новаторский метод возведения конструкций – материал для стен не выдавливается через сопло, а выстреливается небольшими порциями. Кроме того, это совершенно иной материал, который не содержит цемента.

Производство цемента для бетона связано с большими тратами энергии и выбросами в атмосферу. Поэтому швейцарская команда разработала альтернативу на основе глины, ила и мусора от земляных работ. Его производство основано на наработках компании Eberhard AG.

Во время работы принтер выстреливает комки глины со скоростью 10 м/с вертикально вниз. Сила удара обеспечивает сцепление между ними, а по мере печати комки собираются в единое целое. Внешняя поверхность такой стены неровная и требует обработки, но ее можно проводить прямо во время печати, так как материал не нуждается в паузах для застывания — в отличие от бетона.

В настоящее время авторы разработки экспериментируют со стрельбой глиной под разными углами, чтобы создавать сложные конструкции. Сам принтер представляет собой автономный модуль, который монтируется на стрелу экскаватора или крана. Подобная технология способна значительно ускорить возведение домов и снизить уровень загрязнения атмосферы.

    Each courses of compounds indeed improve testosterone
    ranges in males with hypogonadism as a result
    of numerous causes. Testosterone ranges decrease again after the
    brokers are discontinued, implying that they do not solve the underlying
    explanation for hypogonadism. As such, it remains to be seen whether they present efficacy in the
    case of AAS-induced hypogonadism, as PCT is often carried out for a couple of weeks.

    beneficial effect inside this time frame could not be
    excluded (46). Lastly, hCG immediately stimulates the
    testes to produce testosterone by binding to the luteinizing hormone/choriogonadotropin receptor
    (LHCGR) which it shares with LH.
