Thank you! This seems to be the best solution at the moment. Will do more research on this! The price is high but I guess since the manufacturer is making it in low volume it is justified.

Hey,

all my prints that I did with abs failed with a cold bed, but with pla you can print on a cold bed

I would propose you choose the Ultimaker 2+. We have 2 machines and print small production batches in ABS daily. They are really good reliable machines for ABS productions.

you can also search the um blog for more info… https://ultimaker.com/en/community/17706-expectations-and-the-ultimaker-2-or-ultimaker-2-go

Thanks for your comment. :slight_smile: On their site https://www.buildtak.eu/product/buildtak-3d-print-surface/ it says BuildTak works for both PLA and ABS. So you’re saying a cold BuildTak surface didn’t work for ABS for you?

Hello Dirk,

Thank you for the info. Do you happen to know if BuildTak with work with ABS unheated?

Hello Jaime,

I really love the Ultimaker 2+ but unfortunately it is out of my budget as a second printer. I forgot to mention I already own a Zortrax M200 but want to print with other materials such as Ninjaflex, Woodfill, Bronzefill, Carbon fiber etc.

Hello :slight_smile: Maybe time for an upgrade as mentioned by DIM3NSIONS :wink:

Hi

i don’t have any experience with ABS. It’s smell too much. Normally i use nGen, XT, bronzefill, woodfill or PLA/PHA from colorfabb, my two printers have a heated bed.

The buildtak manufacturer claims that its buildtak surface works with ABS, but when it’s pôssible he prefer a heated bed.

You can give it a try without and decides afterwords if a heated bed is needed. The purchase of a UM2go and the upgrade with a heated bed will cost a little bit less then a purchase of an UM2+. So at the end i’ll choose for the UM2+

I have found this offer with nearly new printers: http://www.marktplaats.nl/a/computers-en-software/printers-3d/m1070425060-lay3rs-3dprinting-5-stuks-ultimaker-2-demo-3dprinters.html?c=8c285449651fa109c354bbabe740c1b&previousPage=lr&pos=30

What country are you in? 3dsolex sells a um2go HB kit in most of the world, thegr5store.com (my store) sells it in USA. These places also all sell a 1.75mm conversion kit if you want to continue to use your 1.75mm filament.

Ultimaker specifically will tell you that you can’t print ABS without a heated bed. For good reason. I printed some ABS parts on my um2go last night and even though they were tiny (4 minute prints) I had to enclose the printer completely to get good results.

I recommend staying away from ABS. There are much better materials out there (easier to print, stronger, higher glass temp, less brittle, etc). Why do you want to print ABS and not PLA?

I love my UM2+ with the heated bed. I’ve never had to use tape or glue. The prints stick so hard to the bed that they are difficult to pull off while it is still hot. I usually just wait for it to cool down and they release on their own.

The UM2+ is fairly portable. But if you need something smaller to travel with, go with the UM2Go and go for tape and glue.

16

I’m in Germany. Thank you I have found a store that sells the mini heated bed here! You are absolutely right, we don’t always have to go with ABS. I am also planning to use the UM2Go to print other materials such as Ninjaflex, Woodfill, Bronzefill, Carbon fiber etc… So I think the HB upgrade is worth a shot don’t you think?

17

Even if you only ever print PLA, a heated bed is wonderful. Much easier than replacing the tape every 5 or 10 prints.

18

I am a huge UM2 advocate and when I came to choose another printer I got a second one the same.

Only thing I would comment is that you mention Ninjaflex and this might mean you’d be better off with a direct extruder rather than Bowden tube feed.

19

Very true. I’ve printed plenty of ninjaflex on various UM printers and having the bowden is a disadvantage but you can do it - you just have to learn some tricks and you will end up printing much slower but you can do it. But if I were going to be printing a spool per month of ninja (or more) I would seriously consider getting a different printer. They have a “cheetah” filament that is even easier to print now by the way. Not quite as flexible.

20

Thanks for the heads up. Luckily i don’t mind tinkering around! Maybe should go with less flexible materials like flexible polyester from plastic2print.com or as you mentioned Cheetah or Semiflex. Seems to me they have better surface quality too because of a wider T_g range.

Hey you wrote the firmware! Good job!

22

The um2go power supply isn’t up to moving all the steppers and supplying power to the nozzle heater and also supplying power to a 50W heated bed all at the same time. I did extensive testing of power usage on that thing - was amazed how much more power it uses if you fight the head movements, lol. So I modified the firmware slightly (20 lines of code?) to never turn on the bed heater and the nozzle heater at the same time. It works well - nozzle gets priority. I wrote this code for 3dsolex thinking they would sell thousands of these heated beds for um2go, lol. Instead I think probably less than 20 heated bed kits sold world wide.

23

That’s really niche. I mean how many UM2Gos were sold? If I were to get an UM as my first printer I would’ve went with the 2+ but since it’s my second printer the 2Go seemed viable. Oh well maybe UM will incorporate the heated bed into the “UM2Go+” like the Olsson block if there is a market for it. Cheers

24

Hey gr5org,

my UM2Go is on the way and I am convinced in ordering the HB kit. After reading through some material and the tutorial you wrote, I would like to ask what is the reason for a separate nozzle heater? Why doesn’t the original nozzle heater work with this set up?
