Re: Collaboration, copyleft for hardware - 10 years ago

QuoteTraumflug QuoterichrapI have personally spent almost 8 months talking to real people and manufacturers That's excellent! QuoterichrapAll of the filament PLA/ABS manufacturers I talked too (I can't think of one who didn't) felt their choice of spool was 'good' or should be 'the standard' You see? That's why a one-person effort is unlikely to work. Now we have not only 56 manufacturer spool

Re: Collaboration, copyleft for hardware - 10 years ago

QuoteTraumflug But that's the essential question. Some individual defining his personal favourite as standard somewhere on some web page is entirely pointless. I'm not sure if you are stating my effort is 'entirely pointless' or even that you think it's 'my' personal favourite that I have put forward as a 'standard' - Even if that was not directed at me, it's not a positive view to take. I have

Re: Collaboration, copyleft for hardware - 10 years ago

Quotejaguarking11 I do agree we need to find standards. One of my biggest gripes is having different sized filament spools. Why not settle on a 90mm core or something similar? We do now have a proposed and open 3D Printing Filament Spool Standard - And before you ask why it's not on the RepRap Wiki - I just find it easier to use platforms like Youmagine, GitHub or blogs rather than an enormous

As promised the Universal 3D Printing Filament Spool Standard has now been released. An update and YouTube video explaining some of the challenges and ideas used in the standard can be found on my Blog here A Youmagine page containing the standard and any other files as required is active here And the 3D Printing Association is also supporting the standard, they are interested in feedback fr

Hello Everyone, Just a quick note to say thank you to everyone here who has added comments, ideas and discussion for this universal filament spool standard. I'm pleased to say after a lot of discussions, thought and ideas, a draft standard document has been produced. It's not intended to be set in stone, and it's a completely open standard based on the good feedback here and with many filament

Re: Not quite CoreXY but Sli3DR source files are released - 10 years ago

Hi Mark, At the moment, only all the photo's on Youmagine Here and also on my original blog post about it. I followed the red/blue arrangement almost exactly - I even used it as a guide template in Sketchup for the actual design! (measured correctly of course) Let me know if you decide to build one.

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

Quotewhosawhatsis RIchrap, are you sure about the 120mm core thing? I looked at some of mine, and they had cores closer to 100mm. This is a standard size for cardboard mailing tubes that would make a good source of hubs for these spools. I also have lots of spools with around 100mm cores, and they still make me feel a little uncomfortable with hard 3mm materials. I would like them a little bigge

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

Quotewhosawhatsis Perhaps it we should define one "full-width" design for 1kg, then say that other sizes can be used. For instance, a 1/3W version for a 1/4kg spool that you can fit 3 of in the space of one 1W spool and a 2W that should hold about 5lb (2.27kg). Then a machine built for a 2W spool could hold 1x2W, 2x1W, 6x1/3W, 1x1W+3x1/3W, etc. Exactly, this provides quite a lot of flexibility

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

QuoteChri Instead of making an additional standard , why not to try to use existing spool designs and define one/two (1kg/2.2kg) as standard ? Chri Existing spool designs do not solve most of the problems and are usually not very recyclable. Even many of the filament suppliers I have talked too, say spools are too heavy, take up too much room and they don't really want to ship spools that can'

Re: RepRap Magazine Issue 3? - 10 years ago

Issue 3 is out. The team all gets a little tired of reading and re-reading it by the time another issue is finished, so if anyone wants to volunteer to give it a final proof read for the next issue do let Paulo know, we are always planning bigger and better releases, hopefully more frequently too. All help appreciated. Cheers, Rich.

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

I have had some very interesting discussions regarding actual spool manufacture, from spool suppliers and material providers. It sounds all very viable to make a low-cost, strong and lightweight spool in a variety of ways. We should see some ideas from 'them directly' in the next few weeks, so we need to focus on the discussion of dimensions so they and anyone else interested have something to w

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

Quotewhosawhatsis I'm not sure how the cardboard spools are meant to be held together, but here's an idea I had. Two pieces of cardboard and a short piece of plastic or cardboard tube (length <= radius). You can wrap some packing tape around the center before spooling the plastic to hold the two halves in place. It doesn't have the inner rim that Richrap's design has, but that could be adde

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

@jzatopa - I like the graphic, but I don't see 'any' real standards competing, just some spools that work well for people and plenty that don't. Many manufacturers were not even aware of these sorts of issues for users. They are skilled in plastic extrusion, some don't 3D print themselves and so are not aware how users desire their product. Many spools were just what the manufacturer could get ho

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

@vreihen - Thanks for the thoughts, I'm very aware 'generic filament' is re-sold all over for various prices. Manufacturers making good quality filament are proud to brand it, re-sellers who sell good quality filament are proud to name the manufacture, if they don't then my advice is Do Not Buy It. It's always the very first question I ask any filament seller - Do you make it, if not who manufact

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

@Sublime - Hi Brad, thanks for getting involved. I can't imagine many good manufacturer will want to keep their spools blank and non-marked. at the moment with plastic spools a label can be removed from the spool, if it was on a printed cardboard spool it would be much harder to hide the manufacturer, I hope that's another incentive for actual manufacturers to do something like this.

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

@FuzzyDuck - that's good to know, and congratulations on making your own filament locally. I doubt any manufacturer will want to be told what colour to use, branding, colours and packaging should play a big part in flexibility of the standard as long as key mechanical aspects are met. @KingRahl - I agree you can sometimes help things by re-spooling, but I never want to have to re-spool any filam

Re: Universal 3D printing filament spool standard 2014 - 10 years ago

@toybuilder - Agreed, the main critical 'standard' dimensions are mounting hole and I believe a minimum inner coil diameter suitable for the type of filament being wound/unwound. I was trying to illustrate on my Blog post that manufacturers could comply to the standard but have compatible critical dimensions, in this sketch -
