@CaLviNx said in oozeBot ele^gant:
What QA standard are you working to ?
I do not want to mispeak on a public forum, so will have to defer and only state this type information is forthcoming.
However, the specific QA test I was referring to when comparing materials were specific to heat (80c) and tension (>2x max belt tension).
Parts like this must be very rigid. The part shown was printed in polycarbonate. It worked well but turned out to be unnecessary as we achieved the same results with ABS.
-
For Quality Assurance I was referring to the international inspection standards.
For example the ISO standard or the ANSI standard.
The reason I asked is because I teach mechanical inspection engineering and we work to these international inspection standards.
I use these standards as a benchmark, we have a 3d printing department that I look after where we use 3d printing as a teaching tool, we encompass design, prototyping, material testing, material science etc, it allows me to get paid to play with my hobby.

@CaLviNx sounds like you just might be a good person to know as we move forward..! I'm sure we'll have questions.

OptLaser's new PLH3D-6W-uSpot laser head showed up today.. it appears to be extremely high quality. Here it is sitting next to it's tool holder..
We are excited to test this out!
-
Nice utilization!

Quick pic of our new mesh bed leveling routine I finally got to test today..printed in ABS on a 30x30cm build plate. Not gonna lie though, I didn’t get a picture after just the first layer. This is after four .25mm layers just so I could peel it off the build plate.
We are pleased so far- next up is to do it again with much thinner layers.

I'm tuning our latest prototype with a part set for a default printing speed of 4800mm/min. I keep upping acceleration and jerk hunting the "sweet spot" and I think I could still go higher.. My current config is as follows. And before it gets called out, reminder that Z is belt driven and handles these settings just fine..
M566 X1500.00 Y1500.00 Z500.00 E1000.00 ; Sets Jerk - maximum instantaneous speed changes (mm/min) M203 X24000.00 Y24000.00 Z12000.00 E5000.00 ; Sets maximum speeds (mm/min) M201 X6000.00 Y6000.00 Z3000.00 E1200.00 ; Sets accelerations (mm/s^2)Here is a photo of the print in ABS at these settings:
And here is a link to it printing at these speeds for anyone interested: https://www.instagram.com/p/CF4uDdrj5uY/
Any insight on how realistic it is to push these settings further would be appreciated. Just by modifying acceleration and jerk I've been able to reduce this print from 59m to 51m..

can you post the video to a service that does not need an account to view it?
-
@T3P3Tony my bad - I thought I had that worked out where it could be viewed without logging in. Here it is. Note the rattling is the cooling fan jerking around.. lol. I'm going to have to stiffen that part up!
-
thanks, looking good! I think instagram used to let people without an account see posts but its asks me to login every time i go to a link now.

@oozeBot
Remember that if you plan on selling that laser as a tool for the printer you will need to comply with the FDA guidelines on lasers.
You can get a copy from their website, I highly recommend downloading it and reading it carefully.
If someone blinds themselves with your product you don't want to be in court trying to defend non-compliance.The people selling them as parts are skirting the rules, making it part of your product makes you very clearly liable.
-
@theruttmeister good point! I don't think we'll ever sell them - just point people to OptLaser's website instead. And the tool holder will just be a part we'll make available. Not sure if that carries any liability or not, but we'll make certain we comply! Thanks for pointing this out!

One more video of her running for today.. watch as she lays down a perfect honeycomb infill at 100mm/s!
I just bumped the print speed to 100mm/s and am now down from 59m where I started this AM to 44m total print time! That's over 25% faster.. I'm quite pleased.
And again, the rattling is the part cooling fan..
-
Sneak peak at the enclosure I’ve been throwing together in my spare time for our latest prototype.. am getting excited to wrap this up!
-
The electronics are coming together!
-
Here's a quick pic of our latest prototype in the enclosure I just finished..
-
Just an FYI, the little button with the bent line and two dots under the P0 on the PanelDue display will run bed.g, which could save you a macro slot for Mesh Bed Level that could be used for something else.
-
@Phaedrux just saw this.. thanks! but I am aware.. I actually don't even have 4 macros populating that just yet so I mocked those up for the picture.. lol
-
We just finished running a 300mm tall z-wobble test at 80mm/s and are very pleased with the results! It was done in ABS with a .6mm nozzle at .5mm layer height by .75 extrusion width in just a little over over 3 hours.

Here is the timelapse of it printing.
Note the bad spots in the rear as it prints (and the recovery!). Since this was in vase mode, I didn't use M400 in the timelapse script between layers. It was caused by the momentary stutter when the photos were triggered..
