  1. Hi All For any Aussies this is a great initiative Here. Fill in the form and they'll get back to you fairly quick with the details and model to print. It's the 3D printed part of a face shield and it's a 30 minute to 1 hour print and you send a batch to them at a time. They'll even pay $1.50 per item if you wish to cover your filament cost. They also have a Discord site to discuss etc.
  2. Hi It sounds like you have an error/hole in your obj file. Possibly get a program that can show where it is and/or patch it or start again with a simple base maybe a mm higher than your current base. Once you can get that to slice than cut out most of that base and create your current base again. Just post back if any of this is unclear and if you really get stuck please send the fusion 360 file or share it.
  3. You need to do a "save as" then select type as stl on each part separately. If you are in an assembly right click on the part and choose "open" to open that part in a separate window and then do the above.
  4. Thanks for the update Oliveros. That ABS has a glass transition temperature of 105C compared to PETG (the one I just googled ) of 75C, so it should be much better. You'll have to post a pic when you make your final design.
  5. I haven't printed with PETG but I think it's similar to NEXT GEN. I use UHU glue and a Brim and make spharp corners on the base base round where possible.
  6. Hey Oliveros You could try something like this. Make the walls 2 line widths thick. Shaft_Clip.obj
  7. You may need to print it in a different orientation so the weakness of layer adhesion isn't causing the problem. Check out This Thread. Also you might want to show us the model.
  8. I've done a lot of stuff in 3D, photos etc. and these are done beautifully. Very clear and easy on the eye. Sure does give a better view of the model. Well done.
  9. Hi You just need to check the highest temperature your printer is able to print at and the required temperature for that filament. Which filament is it exactly?
  10. Hi If you make an enclosure for the top of your printer and a door for the front then ABS prints much better. It stops the layers from splitting.
  11. Thanks to the Dev's for continually improving Cura and exploring with the new interface. Personally I preferred the full list on the right as I don't remember all the different settings so I need to look through the list with as little scrolling as possible. An idea I had would be to have a category list on the left which would be a dropdown that you can pin open. The selection of the category would show it's settings in the right list. The right list would open up as long as necessary to fit all of that categories settings in. The Category list would also have "All" as an option.
  12. Hi Looks like you're not starting close enough to the bed. The first layer and brim should be squished onto the bed so that the lines of print are touching each other with no gap in between. Best if you can do the bed leveling routine and give it another go.
  13. Try one of these thermal switches. https://www.ebay.com/itm/9-C-99-C-DC-12V-Intelligent-Digital-Led-Thermostat-Temperature-Controller-/321723841989 You just need to hook up 12V and a good fan. I've been using one with a 4cm fan for a while and it works great but on a hot day it's hard to keep the temperature down for the lower temp filaments so now I have hooked up an 8cm fan. I set it to 45C for ABS and 30C for Ngen. I take my my enclosure off for PLA but if I had to use it I'd set it for 10C to 20C to that the fan is on all the time.
  14. Hi Christian I think this occurs when the print head has to slow down for the corner and still has the plastic oozing out at the same rate which makes more plastic come out over a given distance. Maybe some plastic also gets tossed outwards when the nozzle suddenly changes direction. Either way the cure is to either print slower or if you are designing the models yourself you can make rounder corners where possible. Otherwise your prints look very good. Owen
