The article neglects and glosses over whether the "melted plastic" objects were ABS or PLA (or something else), which quite readily indicates the useful content in the article. (I suspect the research clearly defined that, but the article comes across as "I need to reach my word limit for the next 20 minutes, so I'll just copy-paste a few scary sounding sentences from a research paper, then make up some filler to go between without bothering to understand anything.")
