Recycling Failed 3D Prints with a DIY Filament Extruder: Artme3D

@Alexa (posting here as to not crowd #general channel, but) curious if any delta-style printer designs were considered as an alternative to core xy for the D3D? I've been liking their simplicity (minimal part count) as well as the ability to print on a static bed (akin to a core xy).

They were likely initially taken into consideration for the printer, but the motion system makes for a complex machine. They can print fast on a static bed for certain, but they can't be scaled up in the same way that the CoreXY design can be. It's not possible (if my memory serves) to add additional axes to a delta printer for extra strength, for instance. Also, OSE's focus on industrial productivity demands a design that can be scaled up to print things as large as 4' x 8' house panels for the Seed Eco-Home. The costs savings from having 3D Printers for in-house construction materials production is calculated to save tens of thousands of dollars per house. Also, super big important details I forgot to mention, the core XY design allows for a completely thermally isolated high-temperature heated chamber. The heated chambers will be able to handle all the way up to PEEK/PEAK engineering plastic printing and everything below that. That means that OSE 3D printers (when paired with a filament maker) can produce products from 100% recycled plastic of almost any type.

Also, because of the modular nature of the printer, it can be scaled up or down readily by replacing the frame rebar pieces, the axis rods and belts, and the bed if desired.

I was actually thinking more of a line-driven delta printer, like the hang printer that's designed for scalability https://hangprinter.org/ Though, it might not be robust and high tolerance enough to meet certain industrial specification, unless you're printing with a material like clay (which the hang printer recently demonstrated)

A worthwhile goal! You might also like OSE’s Compressed Earth Block press for more work on the same vein of sustainable construction materials. Also also, 3D printing can certainly be used to make more construction materials than just the walls of a structure, which may be desirable as the walls only represent a small portion of total house cost.

Thank you for sharing, but what am I looking at? By the looks of the photos, it's a plastic mold compressor thing, not a filament extruder.

thats right, goal currently is to produce compressed quality blocks, up to 100cm long, and go from there since injecting & print doesnt deliver good results at all

That sounds great for injection molding blocks, just not for extruding filament

i could however imagine to utilize larger printers as moulding/injection device, eg: pumping or pouring material in multiple moulds on a table, and flip the tool and mill it to shape,

8:18 AM

the makers/customers we have are tending to produce larger and unique objects instead - since smaller ones wont compete well with China ...

3D printing is a perfect tool for producing larger and unique objects. What makes you say that printing doesn't deliver good results?

surface finish, and material strength leaves much to desire - at least for the clients/companies who have been asking about.

CNCKitchen recently used a 3D printer extruder to do injection molding; why choose when you can have both? https://youtu.be/4xXs9go-Ieg

common trend however is to print and then mill it just - but also that works only with virgin materials, often exotic and expensive

Why couldn't you mill something made from recycled materials?

recycled plastic comes often with problems, air voids building up, unknown ingredients, making the process kinda unpredictable - one of the major reasons why recycling is being discarded. we had a customer trying to get even high quality plastic back in circulation but vendors refused to put in their machines

Also, arguing over"Which is better, 3D printing or injection molding?" is a moot debate. Both methods have their merit and place depending on the problem to be solved

Exactly - all tools in the toolbox. It's important to know when to use them and when not to.

Oh yeah this stuff hasn't been dried yet. Right out of the packaging for a print. I do have a dryer but I neglected to use it for this spool yet (which turned out to be a waste). The part was going to be a Y1 axis carriage piece for the 3D printer. @HAL_9000 (edited)

Really slick design. Great job, I am sure that took a hot second to model

Actually, it was pretty quick. I found an open source parametric rugged box design, scaled it up to as close to the print area as possible, and then changed some slicer settings to tell it to remove the top and bottom layers of the print, leaving just the honeycomb infill. It took about 30-45 minutes at most.

I've switched over from Cura to PrusaSlicer about a year ago, but mostly because I replaced my Ender 3 with a Prusa (and converted my Ender 3 into a ReCreator)

I probably don't use all the features, but I've been liking the measurement tool. It should also support non-prusa printers (s.a., Ender 3V3)

To add to the aforementioned, it also depends if you're building off prior work, in which case you should check for what license said prior work is using and license your work accordingly. Otherwise, it's up to you. For 3D printable CAD models, some kind of creative commons license seems to be the norm, especially on platforms s.a., Printables. The only explicitly non-commercial creative commons license is CC-BY-NC-*, so you'll probably want something like CC0 (public domain), CC-BY-4.0 (requires attribution), or CC-BY-SA-4.0 (requires attribution + redistribution under same license)

OK, At this time I released my 2nd tool for Ehlers-Danlos Syndrome with the CC BY-NC licence. Many people ask me where they can buy my tools... Is it hard to create a low-budget "licensing system" (pay X$ per month to sell my models) ? Is it OK with your Open-source vision ?

At the start, my friends doesn't want to open-source that because "You can make money easily". But I think Open-source is the only viable model and many businesses can make money with OS,

1) Congrats on releasing your project publicly! You should make and sell your tools if you have the ability :) 2) It's pretty straightforward to do in an open source fashion - it can be done on wordpress and woocommerce (both open source software). You would create your own website in the process. 3) The noncommercial licenses aren't considered open enough to meet the open source hardware definition (edited)

ok, sorry - just to be on the same page: 'Open Source' - sounds tasty, isn't ? What the heck does this actually mean ? Lets take a 3D Printer related product or product family, BigTree, AnyCubic,... they are anything else but 'open'; if you're lucky you have a silly step file at best; and for sure not the bootloader (often reverse engineered later on, to fix bugs); same for the parts to hold it all together, often even less useful stl files ; nothing open at all; or the documentation about; same story; often put under a rambo license, making it impossible for me as product/system integrator to build anything on top, ...

2:44 PM

OSHW, in the end - another nice attempt to bs ourselves, creating an illusion of freedom when in fact there's none at all

2:48 PM

and to put this into practical perspective, integration, lets take SeedHome; I doubt I could call up the source to integrate changes or fixes

the only things you could call there 'sources provided' are the drawings, blueprints if you like - but thats about it; the actual physical matter remains 99% closed source

it's quite hard to be 100% open source

1% would be already good

actually, whilst at it - just to annoy everyone but great fun to me as one with an allergy for bs, following that principles (also used for package selection during my shopping tours on github) there's on top, dead open source, and living open source - but also dead dead opensource (author gone & abandoned), and maybe dead reborn opensource (project picked up again), what about living-but-actually-no-real-opensource, ... just to mess with your head a bit

in the meantime, I will try to spam the net with new tools instead, plenty to do : media (pics, video), cad, .... and everything what a full & modern company tech stack needs

here a few examples:

fablabs for some reason feel offended when I start talking quality/outcome, small businesses
precious-plastic, claiming to be os, censors everything not fitting aligned with their narrative, prefers to torture their users instead
folks in the maker/creative industry kept reminding me that I forgot to close the sources/designs
larger companies, incl. MIT, or into pharma somehow also disregard open products, nothing coming back, despite big words as #sustainable, #innovative, #circular in their main ads

currently its kinda handy just to pass complete offers & resources around, thats about it

3D Printing Ideas

Why are we drying filament this way?

...Has anyone tried hooking other tools up to a 3d printer? Lasers, cutting implements, drills, grinders and polishers, etc? In theory, you could do a lot more than just print stuff.

Yes! OSE has a milling machine based on the D3D Pro motion system

Neat. Can you get both printing and milling in one machine? Not that I'm entirely sure how useful that would be, but, in theory...

Yes and no

7:05 AM

With a little work you could make a swapable extruder / spindle that you could manually swap

Like, I'm imagining a 3d printer that can also do other mechanical motions. Maybe even reach in and apply pressure, to fold stuff? Not sure how difficult/expensive that would be.

I know that Prusa has a nice open source tool changer, but I don’t know how well it would hold up to the forces and mass of a spindle

tool changers that can apply forces are pretty common. we use hurco multi tool machines everyday and you can get an idea of the tools with this image

I'd personally recommend the Prusa MINI+ as a beginner-friendly open-source hardware, customizable, reliable 3D printer. I've been using it more than my Prusa Mk3S+ lately. If you later decide you need something bigger, like a D3D-Pro, you can use the MINI to print parts for another printer and/or order them from @Alexa

If you want minimal to no tinkering, with customizable options for things like the side panels, you're probably looking at the Prusa Core One
