Shop Talk – So This is why a Floating Ground is BAD!

In this episode, we will be following up on our previous discussion (see more here: youtu.be/fSNMQxkpf18) around the electrical risk and 3D Printers (machines in general) as after a lot of discussion on this thread, the general opinion is the issue Angus experienced was one of a “floating ground” and a Y capacitor. Yet what is a “Y” capacitor you ask? Well Y-capacitors are designed to filter out common-mode noise, and are connected between line and chassis (i.e. ground) to do this. When the earth ground is lost, this voltage can become stray and cause a “touch current” which is more an announce than harmful (because of the low current) yet is an indicator that your earthen ground and therefore your electrical safy has failed.

Also keep in mind for Angus, his mains are 220v as opposed us in North America at 120v. This means he will see a higher stray voltage (around ~70 volts) and because “volts” represent electromotive force, this mean a high likelihood of feeling a shock. The other thing as we discussed in the video, by adding printers (machines in general) to a power strip without a ground, you will be increasing the current (because the voltage will remain parallel) so this can compound the experience.

Note: (1) these types of tests should not be performed unless you are an experienced professional and have been train to work with such voltages and currents as they can be deadly (yes I have had a family member killed by 110v it happens!). Second, I tried to keep this video simple and descriptive and NOT academic so please don’t waste your time nit picking.

You can see Angus’s video here (I got shocked by a 3D Printer: www.youtube.com/watch?v=Lt-0n95GvQo&t=510s ) and I recommend watching if you have not seen it. As in this episode we dig deeper into this potential issue as basically all 3D printers in this type/class work the same. So we will talk about what could go wrong to cause this as well as what precautions to take to avoid these risks!

Also, here is a video which I created a while back on grounding and the CO2 laser which is also relevant in general to concept of grounding machinery: youtu.be/6vztMvWUnmM

Safety Tips!
—————————————————————————–
1. Avoid the use the residential power strips period, if you feel compelled to use a power strip, use an industrial grade such as this amzn.to/2EEYJaz or amzn.to/2CZ22c2

2. Ensure your home has a working ground! I can’t stress this enough and you can test it with a simple tester such as this: amzn.to/2FB6rn9

3. If need to use an extension cord, use an industrial grade of say 16 to 12 gauge. Better yet, use something like this (it come various length) amzn.to/2muQkz1 to avoid the need of an extension cord all together

4. If you are shocked, unplug the device or suspected devices immediately until the source of the problem can be found and resolved!

Shop Talk – Can My 3D Printer Electrocute Me?

In this episode, we will be taking a look inside the JG Aurora A5 as a follow up to a video from Angus Deveson over at Makers Muse as he bought many good points about the risks of 3D Printers in and having proper grounding and the hazards!

GearBest JGAROURA A5 – The Creality CR -10 Killer Unboxing and Assembly!

In this episode, we will be unboxing and assembling the GearBest JGAURORA A5 Updated High Accuracy 3D Printer! This 3D Printer from a performance as well as price point appear for purposes to be the Creality CR-10 Killer! As this thing out of the box come far more tricked out then the Creality CR-10, with Black Diamond Bed, slightly larger build area, easier to assemble and far more features such as auto resume on power failure, semi intelligent bed levels and more over what what say the reigning king of the hill has (i.e. the Creality CR-10)!

In this video we will be first talking little about why this printer, then do a bit of an unboxing to share with you guys whats in the box then we will assemble just to show you how crazy easy it is! Also help with referencing points in the video we have added an index below:

Shop Talk – 3D Printing and Air Quality!

In this episode, we will be talking about 3D printing and air quality, you that “stuff” we all breath in? As back when I started 3D printing, there wasn’t a lot of research on the impacts of this as frank your home is not an industrial building and with 3D printing we are melting plastic and you and your family are breathing in the results of this!

So we also set up this page to capture a lot of work which has been done in this space so you can educate yourself first hand here: diy3dtech.com/3d-printing-and-air-quality-risks/

However what I really want to talk about in this video is how I deal with this in my home shop and how you might be able to also!

Excerpt (3dprintingindustry.com/news/toxic-abs-pla-fumes-3dsafety-org-inquires-vocs-60796/):

The lab tests showed that ABS is significantly more toxic than PLA, but that the corn-based polymer is not exempt form dangerous emissions, especially if extruded at temperatures higher than 200°C. Furthermore (as may be expected), the same material spools, when acquired from different resellers, release very different quantities of VOCs, even if used in the same 3D printer and under the same parameters of speed and temperature.

A second critical aspect is that relating to the emission of nanoparticles, that is, particles with a diameter smaller than .1 micron, which can be absorbed directly by the pulmonary alveolus and the epidermis. In this case, the emissions, when using ABS, vary from 3 to 30 times those that occur when using PLA filament. The test also demonstrated that the time necessary for the nanoparticle concentration in the air to go back to standard levels was between 10 and 30 minutes after the extrusion processes stopped. Through a photo-ionization technology, the study (which has been published on 3Dsafety.org and will progressively be updated with further information) was also conducted on nylon, polystyrene, PET and other materials.
