  1. Is there a problem with printing PLA at a higher environment temperature? Wouldn’t it be like annealing it?
  2. Thank you for the comments, that helps answer my question here and on the related question in another post, about the material station.
  3. Hi, I am starting a sister topic, I am interested in the UM Air Handler/Manager for the UM-S5, I haven't seen a lot of discussion about it. Is it worth the expense? I am mostly interested in raising/keeping a steady temperature in the print chamber. I have not seen a lot of safety issues from our current configuration (filter is nice, but not a major concern).... does the new air handler increase the quality of your prints? Less warping? Will it actually allow one to control the chamber temperatures? What other benefits does it offer? I have seen the promotional videos, I would like to
  4. Hi UM users, I am considering getting a Materials Station for our UMS5. I am at a small texas university, on the coast, so we have high humidity all the time. Also, we want to print a lot of TPU, nylon, and fiber-filled nylon filaments. Right now we just dry our filament every few days, and we have a makeshift enclosure that somewhat slows down the ingress of moisture. a) First question, if the room environment is about 60% humidity, will the materials station (if kept on) keep the humidity in where the filament is at, low enough so that we won't have to redry tpu or nylon, pva, etc?
  5. @JohnInOttawa I know this is an old topic, but if you still have some Xstrand to print, we could do some flexural tests for you for free. We print rectangular specimens 4” long. .5” wide, .125” thick. Metric equivalents are fine. Larry.peel@tamuk.edu. I know there is published data out there, but more test data is always good. we are at a small university that has some reasonable test equipment. We usually conduct tensile and flexural tests.
  6. Thank you for all of your comments. ALso, SandervG, I will try to seperate out some of these. I will pull the log file and post it where you stated..... ALso, I found out that I have been doing some posts on this forum with another id..... I thought they both the same...., anyway, thanks again for all the suggestions! My available time to get on here varies a lot. -ldp
  7. Hello, I use Cura to create and submit prints to an Ultimaker 5S, purchased last August. It is one of about 6 FFF/FDM-type machines we have in an engineering lab at a small US university. I really like the machine, and it has quickly become our go-to machine, but I am continually having problems with Cura. I thought about posting this in the Feedback section, but that appears to be more for the UM website. Please note that despite the issues listed here, we have printed a fairly wide variety of materials and objects, both for student and research use, and like the machine and tolerate the
  8. Its a new year now, and there hasn't been any more discussion on this thread, but I thought that I would add my comments.... found this while browsing to see what people are saying about the S5 Material Handler. I'm at a small US university, and we have 3 Stratasys products (Connex 500 $280K, Objet30 $34K, and a UprintPlus $25K in 2009... a forerunner to the F123 series), and we just got a UM S5 in July. We have about 6 3D printers total, including a Leapfrog Creatr (mixed feelings, not working now), a Robo 3DR1 (Excellent single nozzle machine, but we wore it out!), and a Craftbo
