[图+视频]学生不满现有3D打印机售价 自己用乐高拼凑LEGObot

随着3D打印技术在全球的风行,打印机的售价也不断刷新行业极限,不断涌现出售价低于$400的面向家庭的日常3D打印机。不过对于学生等群体来说这依然 还偏于昂贵,为此外国学生Matthew Krueger用乐高模块以 Makerbot Thing-O-Matic为原型成功打造出自己的3D打印机,并取名为“LEGObot”,不过和传统打印塑料有所不同的是LEGObot通过热熔胶进 行打印,这种材质具备橡胶特性具备非常强的可塑性,此外低廉的价格也是Krueger选择它的关键.

Krueger随后在采访中表示:“整个3D打印机设备的打造我没有花任何费用,在设计改造之初我就对设备所需要的材料进行了规划,但是这样也导致一个问题就是这款3D打印机的实用性质不高。”

通常来说3D打印机都会通过g-code解释程序来对3D模型(比如.stl文件)进行解析,然后在打印终端上进行打印。但是LEGObot目前设计还不够成熟所以在每次打印的时候还需要进行手工调整,这就意味着打印的精细度方面有所欠缺。对此Krueger表示:“目前我需要改善重新编写g-code文件,但这已经超出了我的能力范围。目前我正寻求其他大神的帮助。”
