<p>In regards to the 3D printer, if you use PLA, then there is a much lower melting temperature, and no real need for a hot plate. <br>
And it also changes from liquid to solid much faster.so much less risk if the molten plastic burn, (like sugar, )<br>
Also there's no issue with fumes, !</p>
<p>Hopefully in the next couple of months my 3D printer will be up and running, and self replicating :-)</p>
<p>Cheers <br>

On the H&S side - you can't just "avoid" things you need to do proper<br>
risk assessments. 3D printers are actually quite dangerous devices with<br>
high temperature heads waving around exuding hot plastics. In addition<br>
several of the offered kits contain design flaws (notably the wrong grade<br>
of glass for heat beds meaning condensation can shatter them), and many of<br>
the materials they print emit hazardous fumes.<br>
<br>
If they were operating in an industrial environment they'd require proper<br>
screens, an interlocked lid, safety goggles etc when in use, plus for many<br>
materials also ventilation.<br>
<br>
There are lots of easier ways to kill yourself with a lathe I grant.<br>

I assume "are" not "a".<br>
