In response to the demand by from the 3D Printing community, MatterHackers has partnered with Village Plastics to offer the KVP Filament Koil, a spool-less 3D printing filament. We are launching this product with four colors in both 1.75mm and 3mm, so no matter what printer you operate you too can take part in the Master Spool movement.
3D Printing is an amazing place to be today because of the strong and forward thinking community we have built. Over the past several months, that community has rallied behind the concept of a print-at-home spool and manufacturer provided refill packs, instead of a throw away spool each and every time. As the community has grown, so too has the amount of empty spools we all generate, and when Richard Horne released the first version of his Master Spool design he answered the question many had been asking - why do I have to keep buying more spools? It makes sense to have a single, reusable spool that can simply be refilled when the time comes, but for the idea to truly work the suppliers in the market have to take part as well. It was made clear to us at MatterHackers that the community cared about this idea, and when we decided to create this offering we found Village Plastics. They have been part of the 3D printing industry for some time, and were already developing the KVP Filament Koil. With our powers combined, MatterHackers is now the place to buy your Master Spool filament refills, in the form of the KVP Filament Koil.
With the Filament Koil, making sure you have a compatible spool is massively important. The RichRap v4 spool will accept these 1kg refills, but you will not be able to screw the two halves completely closed, as the spool was designed for 850g of filament. KVP also partnered with Slant3D to design their own version of a spool for the KVP Filament Koil. MatterHackers has created our own spool design to accept the KVP Koil specifically, the design is in the final phases of testing before release and we'll have it out this week.
We have found that spool loading works best by starting to thread the two halves together, then removing the tie wraps before completely tightening down the spool.
There has been some worry about filament without a spool and the potential for tangles. The fact of the matter is that it's impossible for filament to be manufactured with tangles, the only way to tangle filament is to not keep proper tension on the filament and letting it wrap around itself. The same is true of these filament Koils - they are tightly wound from the factory and will not tangle unless handled improperly. To ensure a good experience, follow these steps:
As we have been testing the KVP PLA, we found the following settings work best:
