3DMakerWorld filament = too fat for UM2


Recommended Posts

Posted · 3DMakerWorld filament = too fat for UM2

I just rec'd a spool of white PLA from 3Dmakerworld.com, a US supplier. While the PLA is extruded from 4043D PLA, and is the same Ivory color as I have been getting from ultimachine.com and protoparadigm.com, it is so thick that it won't run freely through my UM2 Bowden tube. The friction it creates leads to serious under-extrusion.


This stuff measures 2.98mm, and while I suspect that they are trying to meet a 3mm spec, it won't work with any Bowden-tube feeder that is expecting 2.75-2.90mm filament.


I've asked for a refund - we'll see what happens with that.


Meanwhile, definitely Not recommended.

    And here's the reply I got from 3DMakerWorld:

    "Sorry to know the difficulty you were experiencing.


    The specification of our 3mm filament is 2.9mm +/- 0.1mm, which is listed on our product page and matches many suppliers' spec.

    Since this is not a quality issue, we cannot provide a refund. You should check back with UM2 to see the diameter tolerance which the printer can handle."

    This is rather late but I sort of ran into the same problem with 3mm filament. I was having lots of issues and never realized that it was the inside diameter of the stock bowden tube on my UM2. I have some high temperature o-ring lubricant that I put on the inside of the tube which helped, but my biggest problem is changing filament since once the filament hits the heated end it deforms and almost always makes it impossible to retract back through the tube. I've resorted to manually pulling it through (thank god I installed roberts feeder).

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
