From what I can see, it looks like the S5 came out about a year ago to this date. Anyone have insight on the possible release date of the next upgrade? Maybe an S5 Extended?
My luck is to buy the older model right before the new shiny one comes out.
who am I kidding...just purchased the S5! Can’t wait to try it out.

7 hours ago, Hudson said:
Glad to hear you were able to get it to print with what you had!
The next material I'm going to print is Arnitel ID 2060 HT from DSM. If you need a higher temperature rating or want your prototype in black you should check it out.
Where are you buying it from? I would love to try it. BTW, I'm currently printing another part with Hytrel and trying supports using the same material. Instead of using Cura, I drew them in with a 0.2mm gap from part. So far everything is looking nice.

Thanks for the advice Hudson. I was able to modify the extruder on my UM2 (Filling all possible gaps near knurled fitting) and replaced the bowden with some PTFE tubing I had on a roll. I successfully printed my design using Dupont Hytrel 3078 and the print looks absolutely perfect. It prints better than Ninja Flex. The total print time was 19 hours. Unfortunately I can't show the print due to my patent process.
I forgot to show the print settings: Hytrel
Quality = 0.1mm
Speed = 30mm/s
Temp = 240c
No Retraction
Fan Speed = 20%
Infill = 100%
Heated Bed = 40c (I use a plate similar to PEI)
Brim & No Support
The part is about 66mm tall and 62mm wide

I have one of the older Ultimaker 2's. I am not able to use Hytrel with the extruder on this machine. The filament just gets pushed to the side when it gets stuck traveling through the bowden tube. I plan on getting an S5 soon, but was wondering what changes have been made to use this type of material. Will I need to modify anything to be able to use this material? Maybe a direct drive system would be better? Any thoughts or direction would be appreciated.

It's been a few years since I posted here. I'm looking at getting a couple more UM3 printers and the material of interest will be Dupont Hytrel TPC-ET. Does anyone have experience with this material and the UM printers? I'm hoping to use it with PVA to create a nice smooth print with overhangs that need the support. I know the print settings will be close to that of Ninja Flex. Any recommendations or knowledge of this material would be greatly appreciated.

Can you see the feeder impression rotate as its going through the tube?
The stock mount the filament would only need to rotate 90degs but yours would need 180 to be in its natural form. Not that i'm saying you way is wrong or bad. I like the design.
Labern, the impression doesn't seem to have any significant cause while traveling through the tube that's any different from any other method. No matter what the degree the filament travels through the tubing, there will always be some friction because the structure is forever changing, due to movement. I understand that. Remember, my main concern was to have the filament as straight as possible while entering the hole that goes into the extruder. The stock extruder created many problems with friction, then causing small pieces of ABS plastic to be lodged into the hot-end, causing blocks/clogs while printing with PLA.
When using a side mounted spool your fighting two degrees of friction instead of one. At least, that's how I see it. I would love to see some testing done, but I probably won't spend the time doing so. I can only say that this particular method has worked for me since the printer cameout. I'm sure this can be improved many times over. Thanks for your input.

Nice one did you publish it on youmagine?
Not yet Didier, it's just something I needed. If others would like to use or modify the original design, then I will put it up for all.
Doesn't the roll unfold on the oposite direction? I mean, that could add tension on the last part I think...I guess your talking about how the printer comes with an adapter that positions the roller against the printer, sideways? My method here is something I've used since the UM2 came out. Before this design I had the spool in the exact same spot, but mounted on bearings that sat against the bottom/base that the printer sits on. I wanted a contraption that was mounted to the printer instead of one that could possibly move when friction comes into play.
Do you notice anything from the friction chrisp?What about extending the handle a little bit so the reel can be on the side of the Ultimaker (and turned around) and the curve could be the same?
This setup works great and has, since I first starting using since I bought the printer. I can almost use a roll of filament to the very end without any noticeable problems. I don't see any reason to extend the handle to the side unless there is a limited amount of space behind the printer. For me this is not the case.
You can see there's hardly any arc and the filament goes straight in.

I haven't posted or even visited the forums since the revamp. I see quite a few awesome and new products available as well in the store. Anyhow, my original low friction spool holder kind of broke to pieces recently, so I decided to design a new one using iRobert's design as a portion of it. I came up with something I call the UM2 Spool Tool. It can support single or dual extrusion and can hold a tool organizer, while still using the original cut-outs. I am a huge fan of using hardware to attach prints and also of big prints. Hardware isn't 100% necessary, but greatly improves the overall look and feel of the design. Another aspect that concerned me was to get the spool as close to the extruder as possible so the only friction that is caused would be from the filament traveling through the tubing.
Here are some pics:

Just as title says, any info would be much appreciated.

Very nice video:
I'm in the process of making one very similar to this from old parts I have laying around at my shop. Instead of a steel bucket I'm using an old evap fan blower housing and some 3" steel pipe for the crucible. If all goes well, the next step will be smelting copper with a completely different setup.
Ha ha im really getting older... posting this in this strange place...
Surely you can't be much older than most of the community here.....

Will,
Since you had abs in that nozzle I fear that it might be the culprit if you haven't found anything else from the suggestions above. When I use abs on the um2 I have to use the atomic method about 6 to 8 times at various temperatures to get all the abs out. I use leftover rolls of white and heat up the hot end to 250 C and manually push the filament through then let it cool to 60 C and manually pull out to clear the nozzle completely. Usually there are little black bits that are attached to the white filament. I repeat until all the black is gone. In order to manually feed I am using Roberts feeder which makes it easy.

Here's the Dishwasher Rack Adjuster print hot off the press before it gets assembled and put through the fail test in the dishwasher. I only had to make 1/2. It's printed in ABS.

I did try to make replacement wheels with XT for dishwasher and they melted in the dishwasher because of the weight it needs to hold. I still had no luck.

Did you print the parts with 100% infill?
I can't open the pics, but now I'm torn between being just plain stubborn or listening to your experience. The reason I'm going through the trouble of this post is because I will have to buy the filament and I want to make the right choice... I know the parts will most likely fail again if I buy them. On the other hand, I can still design, print, and test the part and when I fail I will still have a great roll of filament.....
I wonder what these parts were originally made of.

From http://colorfabb.com/xt-copolyester :
All these efforts have lead to a unique formulation for 3D Printing that features excellent properties : High strength and very high toughness, Odor Neutral processing, High Tg / improved temp. resistance, Styrene free formulation, FDA food contact compliance, BPA (Bisphenol A ) free formulation.
Thanks for the info.
Ok you got me curious enough to try ... I'll put a scrap piece of XT in the dishwasher tonight ... Its a piece of the original, non colored XT. Ill also measure it to see if there is any shrinkage or deformation.
I don't see the concern on food safety, I never eat from my dishwasher
I think all that matters is temperature ... @Chrisp, will there be any force on the part you need ?
I'm not sure if there is a concern when washing dishes clean and having a printed part in the mix, but I just want to be as safe as possible since I care about my family and their well being. I never eat from my dishwater either, but I do eat off the items coming out of it. :mrgreen:
There is some force. It is an adjustment that raises and lowers the top rack so that bigger plates can fit underdneath it, so it holds the weight of the entire top rack when adjustments are made.
I made this test with XT from 2013; at 65°C. There was no color change. However, it is rumored that clear XT gets a bit more opaque when washed at 70°C.
I think mine washed somewhere around 165 F

I think Colorfabb's XT is PET or PET like and is food safe. You can order directly from ColorFabb. Delivery takes about 5-6 days via UPS.
is the official CF US reseller. I've ordered from them and shipment was very quick. Their problem is stock or lack thereof...
Not to discredit your statement about it being food safe, but where did you find where it says XT is food safe? I looked on Colorfab's website and could not find anything.
-
Any recommendations on PET brands sold in the US that are top quality? I haven't used this filament yet. I found some at Made Solid which seems to have decent reviews.

Has anyone printed replacement parts for a dishwasher using ABS?
I have 2 of these rack adjusters that have weak hooks which break very easily. of course the machine is out of warranty now.
Just wandering if anyone has had some luck with dishwasher parts.
-
Did you check the small fan cooling the nozzle end when your under extrusion occurs? It could be stopping. It's suppo to be on all the time. The one directly behind the aluminum block.
Also, check what the nozzle temperature reads until the under extrusion happens. Sometimes you can see Huge fluxuations.
How is your filament mounted? Is it on the factory spool holder clipped to the back or did you upgrade to something better with bearings?
Sometimes at the end of the spool the filament gets extremely tight coiled causing a tremendous amount of friction.
Just trying to give you some other things to check.

Very curious about the end result!
I was able to complete it last night after 25+ hours of straight printing. I did have to reprint 1 small part and fix the file slightly, but it looks, feels, and works as intended. The only thing I'm missing are some 8mm rods about 12" in length. The ones I have are just a little short, but good enough for testing. The carriage weighs about 2lbs. Fully assembled with the brake/locking mechanism attached.
Here are some pics of the MARS 2. There's a total of 12 printed parts and I printed the prototype in my least favorite color, since i had a full roll sitting around.

Some really nice prints on these forums as always.
For the past week all kinds of great ideas have been going through my mind about how to make my dremel workstation easier to print, use less filament, and easier ways to adjust both axis and how they rotate. This is the forth version i have designed from scratch which is called the MARS 2 (GEO) MultiAxisRotaryStation. I dove deep into designing this version with geometrical shapes, tension springs, and linear bearings. the last version did not use bearings and works great, but I wanted to have a version that moves up and down easier. Anyhow, this is what I'm currently printing over the weekend.
-
Love the feeder. The only issue I have is when I'm lazy and decide to actually use the change filament option, the filament always seems to slip off the bearing and knurled fitting unless I hold pressure against the bearing. Otherwise my printing experience has been much better since using Robert's feeder.

I printed this about 7 months ago to hold my bug zapper outside. It's screwed into concrete with tapcons.
Still looks and feels the same as when it was printed. It's not in direct sunlight the entire day but definitely receives enough to effect it. So far it's held up really well.

Another very useful print since each one of these corners costs $15.00 plus tax when store bought. I needed another raised plant bed for some edibles. I'm interested to see how long these PLA printed corners will last through the summer months here in Florida. I used cedar for wood with a couple coats of UV, mold, and pest resistant sealer.
The dimensions are 3' x 5' x 6"H. I designed it to allow multiple stacking levels with 3/4" PVC pipe to slide through the corners to secure it even more and to be able to close in the plants from critters.
The wood costs about $24.00, PVC about $4.00, and the plastic was about 1/2 a roll.
Anyhow here are some pics.
I think all that matters is temperature ...
S5 print head wobbling
in Improve your 3D prints
Posted
Just got my S5 in today. I am noticing quite a bit of vibration and a nasty wobble while printing circles.
Any suggestions?
