  1. maybe someone from colorfabb ( @Gijs ) can clearify the advised printing temperature, I see that on the site now the advised temperature for the regular XT is also 240-260. On the box I have from april it says 250-260, the box I have form june is labeled 240-260 so I assume this advice on printability at 240 is a deliberate change.
  2. Just did a first test with the new colorfabb XT color material (got it at the 3d printshow last week). First test failed as the material did not stick to the bed (let loos around 5mm3/sec), but after a good soap cleaning of the glass that was solved. The advised print temp = 240-260. I printed at 240. At 240 celcius the bonding between the layers is very poor, the print failed at 7mm3/s, but also on the lower layers it takes very little force to peel the layers appart. Will do some testing at higher temperatures later ....but to avoid buying new teflon pieces all the time I would like to keep the temp as low as possible ...
  3. http://www.dezwijger.nl/115742/nl/tegenlicht-meet-up-24-de-nieuwe-makers er is woensdagavond ook nog een "meetup" in pakhuis de zwijger ....
  4. je kunt proberen meerdere tegelijk te printen (dus niet een voor een) zodat er meer tijd is voor de individuele onderdelen om af te koelen..... maar smalle toppen zijn een bekend probleem...
  5. Tried it again outdoors, there is an effect but I find it rather minimal. If you want to try for yourself i've just uploaded the file; https://www.youmagine.com/designs/audio-frame-for-gopro-3
  6. And although some people here complain about the high price of spare parts (I know I'm lucky to live in the Netherlands looking at the shipping cost..) I thought replacing the parts like I just did was not so bad after I got this in my mailbox Reminds me I talked to a makerbot guy at the 3d printshow on saturday and asked him about cleaning nozzles just to have a little bit of fun ... answer; your not supposed to take them appart, you can just click on another one .... bit of a pricy machine to maintain .....
  7. agree, just added a link to this topic in the "visual guide" thread
  8. Ignace, I'm pretty sure it's a dirty nozzle (inside) causing the furry issue.... http://umforum.ultimaker.com/index.php?/topic/7284-furry-prints-how-to-get-rid-of-the-hair/?p=68335
  9. THE FUR IS GONE !! so I started cleaning my nozzle this evening, tried poking it with a skewer, did a few "atomic pulls" but did not get a nice clean tip after an atomic. Decided to go al the way and change my teflon piece and nozzle for a new one. Actually the old teflon did not look so bad, just a little brim, the nozzle was coated with dirt on the inside.... Now with the new gear, PERFECT MATERIAL FLOW, i did see a buildup of PLA on the outside of the nozzle during the first layer, but it has cleaned itself during printing later on, it's still printing atm and the nozzle is perfectly clean. So now I want to clean the old nozzle, I read here somewhere people are using a gas torch for it, but how do you actually do that ? Is there a danger of damaging the brass by overheating easily ?
  10. If we could somehow document when and how to make corrections in CAD it would be a great source to share ..... but personally I'm not that good in documenting though :shock:
  11. @pm_dude, thanks for your testing! About my printroom; it's around 20 celcius, heating is off atm, no airco, no drafts I can notice. I have no idea about the humidity, wouldn't know how to measure it .... I was most surpriced by how fast my nozzle got dirty again, so I'll clean till I'll get a nice straight flow of material again, If needed Ii'll change the nozzle with a new spare one (have one in stock). Try to continue testing tonight... but not sure if I'll get to it... @Didier, if you have a look at your timelaps, please let us know how dirtty (or clean) your nozzle was ....
  12. Tested some more this evening, after cleaning the nozzle again... same model/material (colorfabb magenta PLA/PVA) tested at 95 % flow, no effect at all, still a large amount of furr. Cleaned again (only outside of nozzle) and tried with UM blue PLA, still furry, but a lot less. So I'm beginning to think it's the model (slicing of the model) as main issue, but there's for sure a big difference per material. Some idea's for further testing (later this week...) - same model, sliced again, maybe on a different scale... - same material & setting, different model. I thingk I'll also do a "full" cleaning of the nozzle first, as I noticed at the start of the print the flow of material was not nicely going straight down, but more on one side, this may have something to do with the nozzle getting dirty so fast....
  13. Picture may be not clear as it's from the front but i think travel is not relevant here. Nozzle is just following the outline. Not "jumping a gap"... this is not stringing is also haopens on a flat front.
  14. I cleaned with a tissue after heating up. And with a mini rust brush. Tried the same print... still same issue... will try same model and settings with um pla later ....
  15. Niet zeker maar volgens mij heeft het te maken met de hoogte van de objecten, als er een te hoog deel bij zit gaat het mis. Het beste check je altijd tevoren met layer view hoe er geprint gaat worden om verrassingen tevoren te zien. Zou je toch al moeten doen om b.v. te beoordelen of je de juiste wanddikte hebt gekozen en een geen gaten in je model vallen ...
  16. I see we posted the same issue what material are you using? I only had it with the colorfabb PLA/PHA... and what is the layer hight of your model? I had it at the fairly standard 0.1 here's the link fyi; http://umforum.ultimaker.com/index.php?/topic/7284-furry-prints-how-to-get-rid-of-the-hear/
  17. done cleaning, printing a small testcube right now, no sign of furry fibers sofar.... will print the "problem file" with same setting again tomorrow.
  18. He Gijs, was planning on giving you a PM on this one, but you're here already... The top of the block is clean, so no leaks I guess... I admit the nozzle is rather dirty. Is it that simple that its just a matter of cleaning? If thats the case it could be an issue on longer prints, as I told you saturday I had it on the "nesspreso cup holder" as well on the front side and this is a longer print (20+ hrs). I'll clean and try the same model again, keep you posted. @solid print 3d - Am I right that you think it's "stringing" ? I don't think it is ....
  19. Had this before of an larger print with a flat side, on the front. And now again my print is growing hair. Have only seen it with the Colorfabb PLA (not pure PLA..) in this case there magenta. I varied the temp (210, 215, 200) it seems to be a little less at 200 but still there. Printing fairly standard at 40 speed / 0.1 hight. Any idea what is causing this ? It's only on the front, and more on the right front than the left front....
  20. I think 3d printing is maybe getting into my head just a bit to much ... walking hydepark on sundaymorning ... saw this art and all I was thinking was "overhang" :-P
  21. http://3dprintshow.com/global-awards/ don't think it really exists ....
  22. I've just put a big stack of mostly unsorted pictures in the gallery.... The thing I found interesting was the student (material science?) who worked on finding binding materials to print very strong with soil, wants it to get stronger than reinforced contrete. In the "I want one" category I liked the fuel3D scanner, here's the discount code if you want one... the quality of a printed dress looks a lot different in close up ... These guys where claiming the main limiting factor for printspeed on an UM was the electronics..... ther board would speed things up a lot
  23. And one more thing i was missing was promotion for Youmagine..... did not see any reference to it anywhere... except for on slide in richreps presentation..
  24. Did like the show al lot though... had a nice visit... wil post some pics later when back home again....
