Prusa USS Drybox  

RE:

Anyway, it's Prusa... So the dryer (assuming that what this is) will be formally announced at FormNext, won't be available until 6 months later, will be overpriced, will sell out instantly then followed by a 2-3 month wait to actually get your hand on one. 

RE: Prusa USS Drybox

I haven’t seen any cords so I don’t think it will heat. I’m thinking it will probably use fans to circulate the air inside the dry box??

RE: Prusa USS Drybox

We are all just speculating really on what was essentially a 3D printed mock-up for an April Fools prank. However, if Prusa did intend for an attachable dryer this would indeed be a nice thing to have, especially for Nylon. 

RE: Prusa USS Drybox

The material of the USS box is indeed polypropylene. I did not see it mentioned on the product page, but the help page states it: https://help.prusa3d.com/article/prusa-uss-drybox_1014382

That April Fool's accessory really has a neat form factor. Would be a pity if they don't do something real with it, besides putting the dummy on Printables: https://www.printables.com/model/1657964-prusa-pro-acu-design-files

RE: Prusa USS Drybox

April Fool's aside, water conditioning is a real thing, especially for PA6. Obviously it needs to be printed dry but then after printing the parts should be water conditioned. 

RE: Prusa USS Drybox

It is fun to dream and speculate about what is next.

I was wondering that too - it seems a bit too well designed for a one-off.  I suspect if it was only done as a joke there might be enough demand to turn it into a real product!

They have already put the files online so you can print your own copy.  It seems like a particularly detailed model for just a joke.

It was posted on Printables & Youtube on 1st April.... It features accessories like the rusa Mop and the Prusa Bucket... LOL!!! 🤣 🤣 

RE: Prusa USS Drybox

Great find.   Prusa is so creative.  They are very similar to Apple.

RE: Prusa USS Drybox

It's not really a dryer - it's a 'dry box' - so designed to maintain your already dried filament by keeping it sealed along with some desiccant. I've been suing the coral box solution thus far - this seems like a 'posh version' 😉

Will be picking one or two up for a closer look........

RE: Prusa USS Drybox

It depends on whether that conditioner is just a joke.  If it's a dryer, then it will be more interesting.  I am sure someone will make a printable accessory to plug it into a polydryer.

RE: Prusa USS Drybox

The first USS boxes have reached their buyers. According to this Reddit user, spools other than Prusa will not work to well when printing directly from the USS box: Spools with a larger-diameter central opening will rest on the bottom of the box instead of the core, resulting in excessive friction.

I guess that's the price to pay for the tight fit of the USS box (which brings the benefit of minimizing the internal air volume). Inserting sleeves into the 3rd party spools' cores can work around this according to the Reddit post. But they have to be quite precise, tailored to each filament brand's choice of core diameter.   

RE: Prusa USS Drybox

That is good info to hear at this point. I was holding off and considering feeding out of dryers. Looks like that is definitely the plan now. Tho only issue is the Core ONE L will have 10 INDX heads and dryers only come in 1,2, and 4 spool. 2 five spool dryers would be great. There is still time until INDX comes out for somebody to come out with one. 🙂

RE: Prusa USS Drybox

The 2 Prusa USS Drybox arrived today. 🙂 They look nice.
The challenge will be to make them usable for my MK4S in enclosure.

RE: Prusa USS Drybox

Why do you think it will be a challenge?

RE:

I got my dry boxes for the XL 5T today, surprisingly for Prusa the instructions are shall we say sparse (and that's being generous). It's basically a small piece of paper like a warranty sheet with minuscule text on it. Anyway after reading it, the dry box itself takes 10 seconds to "assemble" (i.e. slide the hygrometer and desiccant into their respective slots. Some immediate impressions:

1. The instructions basically tell you to look at your printer's assembly to figure out how to mount them. After figuring out the instructions were somehow incorrect on my XL to use a 4mm (hint it's a 3mm) Allen key to remove the spool holders from the rails, I got it off to see I have the injection molded one (type "B" per the manual) which is really nice, EXCEPT, it uses a bayonet to lock the parts together, no idea how to depress the lock to slide them back apart...

2. Not sure if the boxes on the right side (i.e. T4,5) go backwards (in other words the hygrometer pointing backwards?).

3. There is an extra O-ring in the box, which is for...

4. The desiccant package is hard to jam into the space for it, like couldn't they have gotten slightly smaller packets?

5. There is the weird instruction to always mount the dry box in a vertical position (as opposed to what? lying it on the side?) That's less helpful. Also it tells you to decide on the mounting based on your printer's manual. Not sure how the manual for a printer I've had for that long would have anything about the dry box which came out years later? Shockingly there are no videos on Prusa's channel to show the process. Of course all the pics on the website show it mounted on a Core 1 and Core 1L rather than the XL (hey remember us who bought the flagship printer???)

Well I am going to see Prusa at Rapid+TCT tomorrow so can ask them there

RE: Prusa USS Drybox

I was thinking to print complicated spoolholders and ....
Now the printer is printing without anything additional. The drybox is only standing on top. No fixation. I just had to prevent the PTFE tube from getting stuck during printing. 

this is perfect for the start!

I think this is in reference to the "universal" spool holder for the Core One+/L.  You just twist it to undo it, opposite to what you did when you first installed it if it came with your printer.

3. There is an extra O-ring in the box, which is for...

At a guess, they are moving towards that bayonet spool holder for everyone.  You can print the parts for it, but you need an O-ring to secure it.  It looks like they expect everyone to print that spool holder and then they supply the O-ring to complete it.

5. There is the weird instruction to always mount the dry box in a vertical position (as opposed to what? lying it on the side?) That's less helpful.

From what I saw on the Reddit thread, the boxes only stack when they are laying down on their sides, so most people are going to have a few of them stacked up on their sides.  So I guess they are telling you not to print from them like that, make sure you stand them upright before you print from them.

Also it tells you to decide on the mounting based on your printer's manual. Not sure how the manual for a printer I've had for that long would have anything about the dry box which came out years later? Shockingly there are no videos on Prusa's channel to show the process. Of course all the pics on the website show it mounted on a Core 1 and Core 1L rather than the XL (hey remember us who bought the flagship printer???)

I think this is in reference to that spool holder again.  Meaning however your printer originally held onto its spools, now you should replace that with their universal spool holder instead, which I think you will already have on a Core One+/L, but you will have to print yourself on anything else, up to and including the original Core One.

The spool holder parts I am talking about can be found at https://www.printables.com/model/1167816-core-one-printable-parts/files under the group "Core One+ specific parts" and are called "puck-universal-r1" and "spoolholder-static-r1".  The "spoolholder-static" should be universal for all printers (that's the part the O-ring fits onto and is removable) but the "puck-universal" screws onto the printer and may be different for different printers, I'm not sure (although the "universal" name suggests it should work everywhere).

I presume you're meant to print the puck and spoolholder, fit the O-ring, then find somewhere to attach the puck, and that's your mounting point for the drybox.

RE: Prusa USS Drybox

Quick question for those with first-hand experience: How transparent/translucent is the material of the USS box? Can you still see the color of the filament clearly enough?

RE: Prusa USS Drybox

Wow, that was 10x more useful than the documentation that came with it!

RE: Prusa USS Drybox

It’s a smoked gray so harder to see exactly, and I suspect it would be hard between close colors
