Good day, it has been a long time since I was active or used my printer. I am dusting off my UM2 and have some new filaments to try out. I am using an older build version of Cura 15.02.1 which has worked very well for me over the years. My question is the a way to go about having the print done in the same direction? How to have the print head travel the same path from start to finish? I am not looking to spiralize the model as I need it to have structural rigidity (it is a storage box). Thanks for any help.

I saw brianmichalk's post about printing the mask from Long Live Your Smile link here : https://longliveyoursmile.com/3d-printable-mask-for-covid-19/ I downloaded the files they created and the idea and shape seem far superior to the N95 design that was released earlier. However I did not like how they popped in the piece, since it seems to compromise the ability to seal off that part of the mask. I made a design change that incorporates the grid from the snap in piece into the mask itself. The snap in piece has been altered slightly as well. To assemble, place filter into mask and then snap piece in to lock filter in place. Getting ready to test print now but posting files in case anyone wants to try or to modify. Stay safe! Printing with following: .6 nozzle 40 mm/s no support needed no raft/brim 100% infill Cura estimating 4 hours 23 minutes using 7.51 meter (59 gram) Mask.stl Mask Filter.stl

The mask design definitely needs work. Huge gaps and hard to conform so air flow is restricted through the filter section. I have to stay home from work for 2 weeks (MA USA shutdown except for essential businesses) so I may play with designs. The file for the design I made is here. Print out twice and rotate 90 degrees to one another when putting in mask Mask Filter.stl

I Just registered using NA as company name since I don't have a company. Have my UM2 test printing mask parts now. I designed a new filter for the honeycomb piece since retractions were killer on printing with the original. Created piece that was half the height of original. Created slits same dimensions as sizing of hexagons so can take two discs and place in mask at 90 degrees to one another (if that makes sense). Parts print 7 minutes faster than original with almost no retraction needed. I may have access to 2-3 more Ultimakers if needed.

Welcome to the forum and all I can say is AMAZING! I am looking forward to watching your project progress and can't wait to see the finished product!

Can anyone give some insight into the print heads? Is the nozzle an integral part of that unit? Can the nozzles be changed or do I need to put a whole new print head in? I am curious since a new AA or BB head is priced at $114.95 here in the US. If I need multiple nozzle sizes, that gets really pricey fast. Especially if there is an issue/clog etc and the head becomes useless.

Anyone have input on the diameter being 2.98 at worst? As long as its under 3.00 will it get through the bowden tube?

I was wondering if anyone has had any experience using Orb Polymer's PLA? They are a newer company based in Texas, USA and they offer a range of colors in PLA at a very reasonable price. They had no tech detail about dimensional tolerance of their 3.00 mm filament and so I contacted them. This is the reply I got: "Orb Polymer 3.00mm ABS/PLA 3D filament, is extruded at 2.93mm, range would be 2.88 to 2.98mm which will run on most Ultimaker 2 3D printers. Orb Polymer is in the process of extruding true 2.85mm spec Range 2.80mm to 2.90mm PETG HP (High Performance) and this will be available online in a week. Initial Orb Polymer PETG HP colors Black, White and Clear." Thanks Orb Polymer Customer Service Assuming the roll comes out at 2.98 mm, will it fit through the bowden tube? Seems problematic, especially with the "most Ultimakers" part of the response. Thanks in advance SK

Mostly Battlefront with my two boys these days.......been keeping an eye out for this Ghost recon Wildlands

@ultiarjan - Any chance you recollect your printer settings for this filament? I have a small spool of this stuff and am hoping to use it sooner than later.

How old is the filament? I have had problems from Colorfabb filament that was old and had gotten brittle. I had ordered some filament and it came from an old batch from the supplier. They had it in their warehouse for almost a year apparently before shipping and I was able to confirm with colorfabb about the production date . It snapped repeatedly as I tried to use it and Colorfabb sent me a new roll. The new roll printed with no problems.

Do you have the file so we can take a look at what it is you are trying to print? Not sure what support is supposed to look like. From the picture my guess is that you have raft enabled instead of brim, which will affect how support is generated.

Yes once I had better settings to use.....,4 mm nozzle is no good. lol It does smell nice when you use it! I haven't played with sanding or staining or a flame on this stuff.......yet

The Corkfill is great to use. I haven't found any other advantages other than the look of the finished product. I wanted to see how it looked as opposed to PLA etc. I like playing with the exotic filaments and am hoping to try a few post finishing techniques to see how it turns out.
