    Nice job, but you could do it a little differently and possibly easier...1 print a black circle outline as a guide to just cut out the white disc to go behind the coloured clear decal. 2 paint the top of the clear printed decal white and slide on upside down...your decal print is reversed prior to putting on the vehicle. utube videos showed the technique for clear decals on dark back grounds

    Another question. I can already print on transparent vinyl (dark colours anyway) and get good results but the resulting sticker is usually quite thick....I assume the decal material is usually a lot thinner? I've not used them since I was a child (some time ago!) and I remember them being very thin compared to vinyl stickers

  • @paterpracticus

    You may be able to get them from a craft shop, but failing that they are readily available online - search 'waterslide decal paper'. Just make sure you get the InkJet type. The decal surface itself is very thin, most of the bulk being the carrier paper. Very much like the transfers for Airfix kits etc.

    Yes, the same acrylic varnish is good for both InkJet and laser printing. You don't actually have to seal laser prints, but it does protect the surface. You definitely have to for InkJet - check out my previous video here: kzread.info/dash/bejne/dKadrsOfaNrcqZM.htmlsi=H0kPOmzQgri_LegM

    Cool project! FYI, most slicers can add "pause" gcode commands at specific layers. I've done it with prusa slicer and on a Creality CR10. I know the printer firmware has to support the command as well, and I don't know if the firmware on the Ender shown supports it or not, but you can change the firmware on an Ender if it comes to that. If you put the pause command in the slicer or even in the gcode file yourself, when the printer gets to that point it will pause without you having to watch it like a hawk. This makes it so much more convenient to embed magnets, nuts, or other things inside a print. Another thing you can do instead of the "pause" is to insert a color change (I believe that's M600) which is intended for you to swap the filament while the printer is paused. Of course there is no need to swap the filament and you could just embed your object and tell it to resume. I didn't hear you make mention of it, so I wanted to make you aware of it in case it helped you out in your project!

  • @paterpracticus
    @paterpracticus2 ай бұрын

    @@paterpracticus Yes the Ender 3/3pro do support pause at layer height within Slicers, I have done it about 5 years ago when I used Cura (Always hated that slicer never had any good prints from day one on multiple printers. Prusa Slicer is a way better Slicer than Cura with better and more advanced features and print for print back to back prinyts between same model with same settings on Cura with no changes to the printer the ones on Prusa slicer always comes out better.) With the Prusa modifiers you can select areas in a print you want to print with different infill % and patterns and even different types of material like PLA and TPU and even print at different speeds at certain areas or even printing multiple objects on the plate each with its own infill and speed or nozzle temp settings and save it all in one GCODE. That is how I make phone cases out of PLA and TPU in one print in one gcode without needing to sit and time everything as the printer will let me know when the next step is available.

    There is no point in using 100% infill ever (maybe if you really want the weight) To make the parts stronger you can do more perimeters and do 50% or less infill The weakest point will always be the layer lines adhesion.
