Unique Prusa XL replace: transport of first items begins, final minute enhancements and FAQs

Lastly, the first manufacturing items of the Unique Prusa XL are prepared to depart the corporate and head to their new house owners! As we speak, we despatched the primary batch of e-mails with directions on tips on how to change XL preorders to common orders (see FAQ under for extra particulars). Proper now, we are able to fulfill solely the orders from the primary couple of minutes of the pre-sale, as a result of the curiosity within the XL was loopy. The primary shipped batches will likely be smaller, however we’ll regularly ramp up the manufacturing. We’ll want a number of months to ship the 1000’s of Day-1 orders. I even have information in regards to the software program and {hardware} adjustments, transport data, and extra, so let’s bounce proper in.

Single-tool XLs are on the way in which with two items!

The primary items leaving the manufacturing facility are the assembled single-tool XLs. As for the multi-tool machines, we’re planning to ship the beta testing items to our exterior testers in about two weeks. We’ll run an exterior beta take a look at for a month after which take about one month to include all of the suggestions. The primary multitool items are anticipated to be shipped in Might 2023.

I’m not gonna deny that we didn’t handle to stay to our deliberate schedule. We’ve been operating intensive testing since final September and ramped all of it up in December once we despatched a big batch of XL 3D printers to exterior beta testers, leading to a whole lot of helpful suggestions and new duties we wished to deal with earlier than transport the printers to you. So it was extremely busy throughout Xmas and whereas we thought every thing was going to be wrapped in January, we would have liked a couple of further weeks to make sure the adjustments had been correctly examined. It was fairly aggravating however I feel in hindsight, it was positively price it. Kudos to the whole crew who managed to see the challenge by way of to the tip!

We need to make it as much as you guys for ready longer than anticipated. All day-1 preorders will obtain two items: an additional print sheet (a double-sided textured sheet) so you possibly can hot-swap it with the default satin sheet. Due to the Loadcell know-how, you don’t should tune Dwell Modify Z for every sheet – it’s so handy! The second reward is a Nextruder-to-V6 nozzle adapter. The XL makes use of a particular nozzle with a steel filament information (so no extra PTFE tubes contained in the extruder) and utilizing this adapter, you possibly can nonetheless mount any V6-compatible nozzle, together with high-flow and hardened fashions.

In the meantime, we had been ending loads of different issues – print profiles, firmware, PrusaSlicer, and Data base articles… there’s a whole lot of work to be achieved with each 3D printer launch and it’s far more than simply {hardware}. And once we change one factor on the printer (e.g., based mostly on the suggestions from testing), it’s usually like dominoes – it impacts print profiles, assist articles, the handbook and so forth.

{Hardware} adjustments

Talking of suggestions from testing, let’s discuss slightly bit about what has modified since December – it’s numerous issues, really!

We improved the general stability and firmness of the whole printer through the use of stiffer steel profiles and extra strong printed elements. To be extra particular about what we did:

  • Changed plastic handles with steel ones for elevated robustness
  • Adjusted the shroud for the print fan
  • Upgraded plastic elements of the Nextruder
  • Adjusted the filament sensor to stop jams
  • Changed X-axis profiles with stiffer ones and adjusted the dimensions of the X/Y axis facet panels to make extra room for RGB LED strips
  • Redesigned the mounting elements for the toolchanger to make future upgrades simpler
  • Improved a number of plastic elements (X/Y Axis)

…and extra! These should not main adjustments however principally small tweaks and quality-of-life enhancements. I already coated a few of these in a current video weblog, so test it out in case you haven’t already. You can too examine the printer within the video with the images of the ultimate product and see how a lot has modified since we printed it. 😉

Software program adjustments and Enter Shaper

Simply to offer you slightly glimpse of what we modified software-wise up to now few months:

We’ve completed the redesign of the whole printer menu, which was based mostly on the Unique Prusa MINI. Now it’s simpler to navigate and there’s a brand new part referred to as Management that teams collectively actions and exams that straight have an effect on the motion or temperatures.

The Settings menu has been redesigned, too. It now options extra superior choices (customizable UI, RGB standing bar, particular choices for preheating) and likewise experimental options. However there have been additionally a ton of adjustments below the hood – we’ll in all probability provide you with a correct have a look at the know-how in a separate dev diary as a result of there’s lots to speak about.

One of the crucial superior options of the XL is the modular heatbed. We saved enhancing the firmware controlling the heating and the absolutely automated first layer calibration (Mesh Mattress Leveling) to ensure that it doesn’t matter what materials you select, you’ll at all times get that completely clean first layer.

Reaching this was harder than it sounds. Despite the fact that the heatbed tiles have enlargement joints, the large print sheet and the mattress carriage nonetheless generally tend to bend barely as they warmth up. As an example, in case you place a small object in the midst of the heatbed and print it from polycarbonate, we might theoretically activate solely the heatbed tile straight below the item. Nevertheless, the temperature distinction between heated and unheated tile would trigger the print sheet to bulge out. Because of this we additionally warmth up the neighboring tiles barely to decrease the temperature distinction. For that reason, PrusaSlicer mechanically locations printed objects within the entrance left nook to make it extra vitality environment friendly.

Variations in temperatures (heatbed vs carriage vs print sheet), warmth dissipation, and switch may have an effect on the preliminary Mesh Mattress Levelling. We added an “Absorbing warmth” operate to MBL that waits till the warmth from the heatbed is at the very least partially transferred to different elements, and solely then the Nextruder performs the MBL process to attain an ideal first layer.

And these are just some issues we added to make the general expertise in step with our different printers – make it tremendous simple to arrange and run and provide you with entry to superior stuff you possibly can mess around with.

I’m certain a lot of you’re additionally ready for one more piece of necessary data: for the final a number of months, our devs have been engaged on Klipper-inspired Enter shaper and Stress Advance implementations. That is our personal implementation for the STM32 naked steel, not a direct port of Marlin – Klipper has a extra exactly applied enter shaper and stress advance and that’s what we’re after. We’re not fairly completed but, however we hope to share some movies with you quickly. 😉

As at all times, launching a product just isn’t the end line for us – we’re gonna maintain enhancing the XL additional and additional, the identical as what we do with all the remainder of our machines.

With the XL, we’re additionally releasing PrusaSlicer 2.5.1 with factory-tested XL print profiles. I do know that a lot of you’re already utilizing 2.6 alpha due to the superior natural helps and different new options. We’d like a bit extra time to finalize 2.6, however if you need, you possibly can, after all, use it with the XL, too.

2kg Prusament and equipment

The XL can simply chew by way of a complete spool of filament very quickly. With the filament sensors built-in, you don’t have to fret about failed prints. Nevertheless, you have to remember that you have to change filament in the course of the print.

Because of this we’re beginning to provide 2kg spools of Prusament filament. We’re kicking it off with the most well-liked supplies, however we are going to regularly develop the vary. Proper now, these are:

We’re additionally including equipment for the XL to our eshop – most notably further print sheets and nozzles with numerous diameters (from 0.25 to 0.8 mm) together with the V6-nozzle adapter that permits you to set up any V6-compatible nozzle into the XL. We’ll additionally develop the provide of nozzles with new sorts quickly (corresponding to hardened variants for printing with abrasive supplies). We’re additionally going to supply a combo of the nozzle together with the heater block, so you possibly can actually swap nozzles in seconds.

Delivery data

Within the first couple of minutes of launching the preorder, we obtained 1000’s of orders. With our present manufacturing capability, it’ll take us a number of months to clear the backlog. We count on to ship lower than a thousand items by Might.

Right here’s when it’s best to count on to obtain an e-mail from us: As soon as your printer is near being shipped, we are going to e-mail you prematurely that your reservation is now able to be changed into a last order. You may edit the transport handle (you possibly can change the ZIP, however not the nation), add extra objects to your order, and choose the transport technique. You may’t enhance the variety of XLs, however you possibly can lower it. There isn’t a deadline for changing the reservation into an order proper now. The reservation date is decisive; as quickly as you full the fee, you’ll bounce into the fitting place within the queue.

If you wish to improve your present reservation for a single device XL and get an XL with a number of toolheads: DO NOT end your order till we begin transport the multi-tool XLs (est. Might 2023).

After the cargo of multi-tool printers begins, it is possible for you to to regulate the configuration of the XL: the variety of toolheads and different parameters, corresponding to selecting semi-assembled or absolutely assembled, and so on. Please remember that in case you add extra toolheads to your present order, your order will take longer to course of.

The semi-assembled model will begin transport in Might 2023. The method of producing a semi-assembled printer is totally different and requires a brand new set of testing machines – these couldn’t be constructed till after we wrapped up the {hardware} on the ultimate XL. We count on to have the testing machines prepared by the tip of April.

We’ll additionally publish an up to date transport desk as soon as the manufacturing is extra steady.

So, that’s it for now. We’ll convey you extra XL information quickly!
