Saying Prusament Refill, Matte PETG, Versatile and Biobased Resins

We ready one other superior batch of supplies for all of you 3D printing lovers on the market! This time, we’re introducing an often-requested Prusament Refill (grasp spool filament refill system), new great-looking PETG Matte Black, and we’re additionally increasing our line of resins with the BioBased60 and versatile choices! Let’s have a look!

Prusament Refill

The concept of a master-spool-like refill system is one thing we mentioned even earlier than we first launched Prusament in 2018. It turned out to be fairly difficult to get proper, as we defined in our article about the design means of the Prusament spool, and we ended up releasing Prusament with the light-weight sides very properly by now. The plastic sides are comprised of 100% recycled materials and they are often separated from the cardboard core. Now, we’re prepared to supply a refill system with none plastic sides in any respect, whereas sustaining the proper high quality Prusament is understood for.


The prevailing refills for the master-spool system are normally shipped simply as a coil of filament tightened with a few zip ties. Once we tried this method, the danger of the spool untangling or the winding getting fully free was fairly excessive. And the manufacturing course of was fairly difficult, contemplating our extraordinarily tight calls for for diameter tolerance and shade consistency. In order that was not a viable resolution for us.

One of many key methods to getting this to work was to hold the cardboard core within the spool. It gives a number of help to the filament winding. The largest chunk of growth was spent on creating a producing jig, which permits us to wind the spool in the very same approach our customary Prusament is made. Then, we tighten it and safe it with a large strap created from Tyvek – artificial high-density polyethylene fibers. These straps are extraordinarily tough to tear, however they’re extraordinarily skinny and waterproof. Truly, it’s possible you’ll know this materials from the straps festivals use for marking attendees. As soon as this half is completed, the perimeters will be safely eliminated. Vacuum packing the spool fixes every thing in locations so tightly, the spool doesn’t even want a field to be shipped, reducing the quantity of supplies required for manufacturing and eliminating potential waste.



For the launch, we’re releasing one common PLA and PETG shade from our lineup – Prusament PLA Prusa Galaxy Black Refill and Prusament PETG Jet Black Refill. Based mostly on the demand, we’ll be making extra colours obtainable as a refill. Please, tell us what shade would you prefer to have obtainable this manner within the feedback!

Matte Black PETG

Introducing a brand new filament shade is normally not that thrilling information. Nonetheless, on this case, we beg to vary! PETG is notoriously identified for creating prints that don’t look pretty much as good in comparison with PLA. Nonetheless, we love PETG for its mechanical properties and ease of use – for instance, the printed elements on Unique Prusa printers are printed from PETG. And for useful elements, aesthetics are usually not a precedence.

The principle cause why PETG prints look a bit worse in comparison with, for instance, PLA, is its glossiness. Effectively, we discovered a strategy to make it look matte (and thus actually good!) and our first launch is the Prusament PETG Matte Black, however extra matte colours will observe sooner or later.

Prusament PETG Matte Black is coming to our eshop in November 2022!

New Prusament Resins

We hold increasing our line of high-quality Prusament Resins and this time, we’re bringing one thing fully new!

Prusament BioBased60 resin

With the brand new BioBased60 resin, our purpose was to create a product with the very best attainable content material of elements obtained from plant-based sources whereas sustaining publicity instances and reliability throughout printing. And we succeeded – we now have created a resin with the highest proportion of renewable elements available on the market which makes no compromises within the stage of element or pace! So, should you’re in search of a printing materials that can ship intricate objects with wonderful ranges of element, BioBased60 is a superb selection.

If you happen to’re questioning why we named our new resin BioBased60, it’s as a result of we wished to replicate the content material of plant-based supplies within the identify. In different phrases: 60 % of BioBased60 composition is made up of elements derived from pure sources. To be a bit extra precise and technical: Its acrylic monomers are produced from pure oils and terpenes, comparable to α-pinene obtained from pine timber which provides the resin a good pine-tree-like aroma. It is a main distinction in comparison with typical resins as a result of their elements are derived solely from petroleum-sourced merchandise.

The resin nonetheless requires cautious dealing with (and disposal) like some other resin, so hold that in thoughts.

The Prusament Resin BioBased60 is on the market in three colours (Pure Yellow, Natural Inexperienced and Magma Pink) in our e-shop.

Prusament Flex80 is coming!

You too can sit up for one other resin kind coming to our eshop, the Prusament Resin Flex80 and because the identify suggests, quickly, you’ll have the choice to print versatile objects in your SLA 3D printer. The principle benefit of our upcoming Flex80 resin is its skill to retain unimaginable element and complicated constructions in SLA prints. Its hardness is round 80 Shore A and it’s just like a automobile tire or a rubber shoe sole.

This makes the Flex80 best for printing technical elements (spacers, tires for RC automobiles, and so forth.) and organic-looking objects (pores and skin, organs, and so forth.). Printing with versatile resins is barely tougher, however we made certain that our SL1S can deal with it with ease. Utilizing thicker and denser helps or a high-viscosity printing profile is really useful to enhance the printing high quality of complicated objects.

And that’s not all – we even have extra Powerful resin colours coming!

So hold an eye fixed on our e-shop, we are going to inventory the Flex80 and extra Powerful resins within the close to future. 😉

Pleased printing!

Resins have been developed with the help of TAČR (Expertise Company of the Czech Republic).
