2016年5月19日 · Hull and his formidable invention, the SLA-1, are being honored, according to a press release from 3DS, for ‘transformational impact in engineering and manufacturing.’

NEW YORK, New York, May 18, 2016 – The American Society of Mechanical Engineers (ASME) announced today that it has designated SLA-1, the first commercial rapid prototyping system introduced by 3D Systems (NYSE:DDD), as a Historic Mechanical Engineering Landmark. SLA-1 was developed in 1987 from the work of Charles (Chuck) Hull, the inventor ...

2016年5月25日 · As a Landmark, the SLA-1 joins a list of over 260 game-changing innovations, including the Wright Flyer, Model T and Saturn V rocket. At the landmark designation ceremony at 3D Systems’ headquarters, Chuck Hull shared the story of his first print and his expectations and surprises in the decades since.

2017年8月23日 · By 1987, the first SLA commercial 3D printer was produced, fittingly called SLA-1 (pictured below). Hull would later become a co-founder of 3D Systems. SLA is a photopolymerization process in...

His innovation combines optical scanning and laser technologies to print precise physical parts, using liquid polymers. This additive manufacturing process accelerates production design, creating prototype parts and concept models with a quick turnaround time. This is the first machine shipped by Hull's company, 3D Systems.

SLA Ⅰ类分子高度多态的α1和α2区域共同构成了病毒抗原肽结合槽,能够递呈抗原肽至CD8+细胞毒性T淋巴细胞 (CTLs),并将其激活进而杀死感染的靶细胞,从而诱导宿主产生特异性细胞免疫应答。 由于SLA-Ⅰ与病毒T细胞表位结合是CD8+T淋巴细胞清除感染细胞的第一步,并且SLA对抗原表位具有严格的限制性,因此研究SLA Ⅰ类分子的多态性对于阐明SLA-Ⅰ与病毒CTLs表位相互作用的分子机制具有重要的科学意义。

2015年6月9日 · The first 3D printer ever made, the SLA-1, is now on display at the National Inventors Hall of Fame Museum in Alexandria, VA. Go check it out!

2018年3月23日 · 当时还不叫“3D打印”，Hull将这台机器命名为“SLA-1”，功能描述为快速成型，Hull发明它的起因是为了缩短创建产品原型所需要的漫长时间，当时使用一次性模具工艺大约要花6-8周。

SLA基因包含高度多态的SLA Ⅰ类、SLA Ⅱ类和相对保守的SLA Ⅲ类基因，高度多态的SLA-1基因是经典的SLA Ⅰ类基因，目前IPD-MHC(Immuno Polymorphism Database-MHC)数据库共收录了89个SLA-1基因(Release 3.9.0.1 07/2022 build 209)。

Offering a superb level of sound quality, the SLA-1’s clean and powerful circuitry combined with a straightforward user interface quickly and easily delivers the power you need for a wide variety of project and professional studio environments, broadcast and installation applications.
