This is beyond awesome! If 3d printers are going to be like that in the future I suppose 2 things will be needed: 1 - smaller extruders (because the printhead has to be small as possible to avoid collisions. If they can figure out how to use bowden extruders effectively when printing at 600mm/s, they would be a good option). 2 - Multithreaded filament spools.
Thanks - agree - either smaller extruders or bigger printers! - This is modelled on a RatRig VCore4 400x400. I think rotating the front gantry around and maybe offsetting the hot ends so that they can go quite close to each other in the X and Y directions would help. For the filament - what it would like to see is some sort of spool management /splitting solution - where you feed in one or two rolls and it unwinds it and divides it up into separate internal spools - which it can then target at whatever print heads require it.
@@dwuk99 It sounds what you are talking about is something like a reverse Palette 3 machine. which instead of splicing. splits filament on demand. Also I believe remote extruders will need to make a come back. On the subject of big machines, the other day I saw a video in which a guy printed a giant (benchy like but real) boat using a diy large scale format printer. This is definitely a use case for machines like yours (I don't mean benchy style boats, just regular boats).
Look pretty amazing, cant wait to see it on a machine :D Two thoughts I had about you process: 1. You could increase strength significantly by choosing the shape of the middle part in such a way, that the width alternates between normal, and wider by two times the infill grid distance in the width direction. With a suitable infill pattern (one that stays symmetrical to your center piece regardless of z-height) you should be able to perfectly match the pattern and create a very strong bond. 2. You could also use your middle piece to include any non symmetrical features of your part.
Thanks - good idea -. In this version I cut up the middle part in the slicer - which I think can only do straight lines. But there are plenty of other ways to do this - either in design software or in a gcode post processor that could take into account the suggestions you made. Agreed also about the middle bit - which is mainly there to avoid head clashes - but also for the particular model I chose has non symmetrical parts.
Have improved my demo based on your suggestion. I ended up creating some 'cutter' parts using F360 - and then applying them to the model in the slicer as 'negative parts'. Have done a bit more explanation and some pictures here. forum.duet3d.com/post/348585
This just popped up in my feed, looks awesome!!! I really was thinking about this in my head and calling it DIDEX (dual independent dual extruder) but with my January finals I really don’t have time to model a machine. I was also thinking about implementing the hybrid coreXY thing that RatRig has with their larger core-4 printers. I will definitely turn this into reality some day when I have time, are you active in any other social media?
@@王宇-k5c thanks. I occasionally post on facebook. The printer in the animation is actually a Ratrig Vcore4 Hybrid IDEX RMMU 400 (with the kinematics doubled up) and most of the parts hidden (other than belts and motors). See earler videos in the series for the while printer. I agree that parallel printing has to be the way ahead. I'm in the ratrig facebook group. I'm posting most of the details about this initiative on the Duet3d forum.
