I've seen the designs on youmagine and thingiverse, but I'm not sure which one is considered a good design. Any features I should look for to pick a "good" shroud? My goal is to have the best print quality possible, I do not care about print speed.

I know everyone says don't paint it black because you won't be able to see the screw holes, but what if I paint it black on the outside and red or blue on the inside? I should still be able to see the holes if I have to disassemble the printer right?

The girl answering the phone was very nice. There was some confusion with them entering my email incorrectly, but I called and got it corrected. After that I got a confirmation email same day and they shipped on the same day. So far I am very happy with the service, I wanted to have the bed for Thanksgiving break so I would have the time to properly install it and it looks like Makershed will make that happen.

Thanks for the advice so far. If I print with ABS would I need to remove the glass bed and print directly onto the aluminum plate? Any recommendations for ABS?

This thread has nothing to do with regulations... If you the feel information that's been linked in this thread and the associated medical literature carries no scientific merit then you are entitled to that opinion, but I would have to disagree.

Gentleman it seems the problem is resolved! I followed the advice by Gr5 and found that the some of the wire plugs underneath my printer were half unplugged. I pushed them all back in and now I'm 40 minutes into a print when the last two have failed by 20 mins. I love this forum, thanks for the help.

Looking for good fans and shroud designs to put on a UMO dual extruder.

I what to paint my UMO, but not sure what paint to use, obviously I want one that can handle the temperatures of an enclosed UMO and will not easily chip off onto my prints. I also would prefer not to disassemble the entire printer to paint the side panels... So, it looks like I will be painting it by brush while still assembled. What paint should I use? Any type of brush recommended?

The thread isn't specifically referencing toxicity. The thread is addressing the potential health outcomes of nanoparticles when inhaled. Non-toxic particles can cause damage through instigating a chronic inflammatory response. Particulate properties such as size and charge influence their ability to stimulate cells. These mechanisms are well established in the medical literature and I encourage you to investigate them.

I woke up this morning to my print being prematurely halted and my UMO ulticontroller stating "error: max temp". I turned off the printer then turned it back on to restart the print. Print started fine, but when I came back 20 mins later the same error message was there and my nozzle said it was well over 300 C! Why is my printer giving this error about max temp? How can I fix it?

Jamesshs Do you have a link to a guide for UMO maintenance? I've only had mine about a month and would like to make sure I am taking proper care of it.

I have the Ultimaker Brand UMO glass heated bed on the way. I prefer to keep my glass smooth and not scratch it. What is the best method for printing with a glass bed, removing prints without damaging the bed surface, and keeping it clean?

What device did you download it on? I have it on my phone and it worked relatively smoothly, I think my issues was operator error in not taking enough pictures.

Interesting, will read more about this. Another way of smoothing I have seen is acetone vapor, YouTube has a few videos detailing the process

Went ahead and ordered one from makershed, will update you all on the service when the heated bed arrives

Are any of the above listed items compatible with the UMO?

Yes, I meant Celsius for the Printer, but Fahrenheit for room temperature, American habit. I am able to manually push filament through the hot end, doesn't seem like too much resistance. Even with the bowden tube on, I can still move the filament up and down using only my pinky finger and thumb grasping the filament, albeit with some mild resistance.

Great thread, I'm looking forward to the community's suggestions.

Gr5 You make a good point. The potential difference though is in the level of nanoparticles released and the duration that they remain elevated in the local environment. Some people have their printer running for 6-8 hours a day or even longer. The concern is long term as high environmental nanoparticle concentrations lead to the release of proinflammatory cytokines from cells and the induction of oxidative stress which damages tissue. Certainly not a process that causes significant harm overnight, but given a long enough course this could lead to negative health outcomes. I was noticing my asthma being triggered by printing, which makes sense given asthma is a disorder of inflammatory processes. I'm certainly not going to let this detract me from 3-d printing, I think the solution is easy for anyone with concerns, simply build an enclosure with a filter and/or increase the ventilation in your print room.

I think I will be going with acrylic. I can purchase aluminum extrusion profiles, but I don't see how I could easily mount them to the UMO with acrylic plates because the UMO has wood pieces with screws protruding from the surface that prevent a flat even mount. Any suggestions?

I am printing with Ultimaker brand filament, 30 mm/s, 220 degrees Fahrenheit nozzle temperature, 54-57 degrees Fahrenheit room temperature. So I think that rules out a lot, what is left is partially clogged nozzle, deformed nozzle elements, and feeder pressure is too high. How narrow down which of the above 3 is the cause? I think maybe I pull the feeder latch too tight, but I am not sure what is too tight and what is just right?

I feel as 3-d printing progresses and begins to become more mainstream, we should start to consider the potential health impacts of printing within our homes. I haven't had the chance to read through the medical literature, but there was one study that caught my eye and I found interesting. It examines the level of nanoparticles that are released during 3-d printing with both PLA and ABS. The study raises an important question regarding these nanoparticles; could they be impacting our health? http://www.sciencedirect.com/science/article/pii/S1352231013005086 Many may state that as long as 3-d printers stay below the level of combustion, certain toxic by-products are not produced. However, it is important to note that we are assuming manufacturers are disclosing all the material contents of their filament, which may or may not be the case. In addition, sometimes even inert materials can cause lung and other health issues such as long term exposure to fine particles of clay dust leading to silicosis ("Potter's rot"). Could the nanoparticles that arise during 3-d printing also cause such issues after long term exposure in a poorly ventilated environment? I know in the month I've had my printer, my asthma seems to be triggered during printing times and several hours afterwards even with just PLA. To resolve this issue, I am going to be building an enclosure for my UMO, with a carbon filter, and a hose linked to an old dryer vent for additional ventilation. I am open to suggestions from the community and will share instructions once I complete my design. This thread is not intended to cause panic, but rather to stimulate thought and encourage this intelligent and innovative community to consider the possibilities and offer solutions.

How much influence does filament have on print quality? Is colorfabb really the best, are their cheaper alternatives that perform similarly?

This is a good thread.

I will likely purchase an official Ultimaker Heated Bed. I honestly would prefer to purchase it used seeing that it will likely be an enormous hassle with a long lag time and an expensive shipping price because the USA distributor does not ship the heated bed, rather it will come from the main office...
