有句英语句子结构不明白?Volker Zollmer team from the Fraunhofer Institut

首先
句子主干
VZ has developed a heat generator.
Volker Zollmer (team from the Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM),Germany,) has developed a heat generator（ is manufactured by printing,with an “ink” special.）
PS Germany是插入语
team from the Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM)这句话是修饰前面的VZ,是一个长修饰,割裂了VZ和谓语has,让人有些云雾缭绕的感觉~
这里我觉得应该是把manufactured 看成形容词,人造的.这样在
a heat generator is manufactured by printing,这句话中,就可以嵌套一个省略公式,
n +定语从句引导词+be+adj+介词结构,此类句型中,定语从句引导词和is可以省略或同时省略.
既把that省略了.
我个人理解是这样的,这个句子修饰复杂,主干就是VZ has developed a heat generator.
如果想要讨论一下或者让我帮您翻译请追问.希望对您有所帮助.

没错 is 之前一定要有 which 或者that. 否则不通
这整句感觉都有点怪...
正常人都会说 The Volker Zollmer team........with a special "ink".

对啊，去掉is吧
