Filament for 3d printed injection Mold


Recommended Posts

Posted · Filament for 3d printed injection Mold

Anyone have experience with 3d printing Molds for desktop injection Molding machines?


the machine I was looking at recommended at least 160c HDT and I’m wondering if the xstrand filament would be able to handle that?  


Or is there any other filament that the Ultimaker s5 could print that has a high enough HDT?

    I did find that Proto-Pasta makes metal filled HTPLA.

    On their site it says that when heat treated will be stable to 175c.


    Thought Id post that in case anyone else was wondering this.

    hopefully ill be able to test this in the next couple months

    I doubt if 3D-printed plastic moulds can handle the mechanical load? I have had two-component resin parts shattered and flying all across the room when subjected to a load of only 5kN (500kg). Most injection moulding machines go up to metric tons.


    You would also need to polish the mould-surfaces quite well to be able to release the parts, removing all layer lines, and you probably still need to use a lot of release spray. But it might work for making chocolat or gummy bears though...   :-)


    If it would be for industrial/prototyping use, what about a cheap aluminum prototyping mould, for up to 10000 copies? I think companies like Protolabs can do this?

    Yea the more I look into this, I think the printer has to be a high-temp printer that prints PEI filament, or resin printer with high temp resin. 

    It does seem to work for micro injection Molding machines though...under 100 part run per 3d printed Mold.

    It was mainly the cycle time of 60 secs per part that attracted me , and without the added cnc cost.


    Im Curious if ultimaker has plans of a printcore that could Handle PEI filament in the future?

      • 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
