Prusa Core One: Innovating or Catching Up? – 3DPrint.com

Disclosure: The Core One was supplied to me by Prusa freed from cost for the aim of this assessment. I’ve not obtained some other compensation. All opinions expressed are my very own, and Prusa has had no affect on the content material of this assessment.

The Prusa Core One is the eagerly awaited ‘next-gen’ CoreXY 3D printer from Prusa. Constructing on the dependable MK4, it gives an improve path with an enclosure and elements to create a CoreXY. This printer delivers spectacular pace and precision, catering to each hobbyists and professionals. Its modular design ensures simple upkeep and future upgrades.

Unboxing 

Packaging High quality

As I’ve come to count on from Prusa, the packaging is high notch, with simple to take away handles and loads of foam and cardboard to totally safe the Core One. It, after all, got here with Haribo gummy bears (the very best a part of unboxing a Prusa).

Meeting/Construct High quality

At first, I assumed the Prusa got here with panel gaps within the metal body, however I’ve realized that these are intentional and are literally very constant. After realizing this, I can confidently say that the Prusa Core One is constructed like a tank. The whole lot is cosy and tight with no wiggling, vibrating elements, or any play in any of the techniques.

First Print and Impressions

The startup and preliminary print was a seamless course of. Turning on the Core One, you might be greeted with a self explanatory walkthrough of the setup and preliminary calibration. My first print was the 3dBenchy, printed in ASA.

{Hardware} and Specs

Primarily based on the MK4, the Core One upgrades the construct quantity from 250x210x220 to 250x220x270 utilizing primarily the identical elements. The body is laser lower and powder coated metal. The inner printed elements are Prusament PC-CF. These printed elements are a welcome improve over the historically PETG printed elements from Prusa printers. One of many standout options is the cutouts on the left and proper sides of the printer to accommodate an built-in spool holder and equipment. For me, the defining characteristic of those cutouts is that the interior air quantity is closely lowered. This implies the construct plate must warmth up much less air quantity, making it extra constant when printing increased temperature supplies like ASA, Nylon, and PC.

Software program and UI

Software program is the place Prusa dominates the patron market (and even some industrial printers). Prusaslicer, constructed on the open-source Sli3r, is the bottom for a lot of different slicers, from Bambu Studio to Orca slicer, and even many skinned variations from different firms. Prusa has lengthy been a pacesetter within the growth of those slicers and have additions. As for the UI on the printer, I believe the small scroll wheel-driven display is user-friendly and straightforward to grasp, however is a bit of missing when in comparison with the competitors that makes use of touchscreens with a extra fashionable UI.

Check Prints and Efficiency

Time-lapses and Digicam

Sadly my unit didn’t include a digicam, however one is obtainable for buy, although at the moment, it’s solely utilized for fast snapshot views for total print standing indication. There isn’t a strategy to do a video dwell feed, or make a timelapse, because it solely sends one body per second.

Print Examples

Accuracy Check Outcomes:
X Measurement: 100.03 of 100mm
Y Measurement: 100.05 of 100mm
Z Measurement: 100.00 of 100mm
XZ Measurement: 135.07 of 135mm
YZ Measurement: 135.08 of 135mm
XY – A Measurement: 150.03 of 150mm
XY – B Measurement: 150.03 of 150mm

Precise Print Pace

Whereas this isn’t the quickest printer I’ve total, it is extremely constant and is my quickest TPU printer. With the journey pace maxing out at 320mm/s, that is nonetheless fairly a quick printer, however there may be an emphasis on high quality over pace. The Core One can attain 600mm/s for journey pace, however I do want the slower print speeds for higher high quality.

Precise Materials Capabilities

The Core One comes with a normal brass nozzle. This limits a few of its capabilities with bolstered filaments. I used to be solely capable of take a look at “pure” polymers with no components. I used to be capable of efficiently print PLA, PETG, TPU (95a, 92a, and 90a, although it has been a nightmare making an attempt to dry the 92a TPU), and ASA/ABS. I did strive PA6, nevertheless it warped an excessive amount of through the printing. I believe it’s an actual miss on Prusa’s half to not embrace a hardened nozzle from the manufacturing facility, and that the times of plain brass nozzles are lengthy gone in favor of so many extra capabilities. I did wish to take a look at bolstered filaments, however the Diamondback Nextruder nozzle I ordered remains to be delayed from arriving previous the purpose of this assessment. I’ve full religion within the Core One’s skill to print all of the above talked about supplies with reinforcement as soon as the nozzle is hardened.

Noise Stage

The Prusa Core One is without doubt one of the quietest CoreXY printers I’ve seen in a very long time. With minor peaks round 60db and valleys round 40db, I’m averaging ~48db. I’m completely snug having the Core One operating proper subsequent to me—I can hardly inform it’s operating. After I crank up the pace, I’m seeing a better common, a lot nearer to the 60db peaks, nevertheless it’s nonetheless on the quieter facet, particularly in comparison with rivals like Flashforge and Bambu Labs.

Reliability and Upkeep

I had one situation on the Core One: a print failure in ASA that resulted in a buildup round the entire hotend. In making an attempt to clear this up, the Nextruder nozzle that got here with my machine was broken and I wanted a substitute. The nozzles are pretty priced and ship shortly from Prusa. I do wish to be aware that I reached out to my contact at Prusa and so they expeditiously fastened my situation. Upon additional dialogue with the Prusa group, I’ve come to comprehend that all the pieces is fixable on the Core One. Opposite to most of the different closed-off rivals, Prusa has printable substitute elements and gives each single part of their store to repair and substitute as you want. There isn’t a locking down any a part of the Core One. From the bottom up, the Core One continues Prusa’s affinity for consumer repairability and upgradability.

Value and Worth

The Core One has each package and assembled variations. The package is priced at $949, whereas the assembled printer prices $1,199. These costs mirror the upper finish of the patron CoreXY value vary. With the benefit of repairability and upgradeability, and no must be connected to the cloud, I believe these costs are value it. Prusa is main the way in which with consumer repairability and open-source software program growth with Prusa slicer. The Core One gives a lot extra by way of capabilities and stability over the Mk4s. I personally assume the Core One is way value its price ticket.

Professionals

• Repairability
• Low working noise
• Open-source slicer
• High quality of elements
• Ease of use
• Offline usability
• 90a TPU functionality

Cons

• Premium value
• Brass nozzle comes customary
• Onboard UI is dated

Abstract

The Prusa Core One, a next-generation CoreXY 3D printer primarily based on the MK4, gives an enclosed design, upgraded elements, and a bigger 250x220x270mm construct quantity, delivering spectacular pace, precision, and modularity for hobbyists and professionals. Its sturdy metal body, high-quality Prusament PC-CF elements, and revolutionary facet cutouts for spool holders guarantee constant high-temperature printing, although the usual brass nozzle limits bolstered filament use.

PrusaSlicer leads in open-source slicer growth, however the printer’s scroll-wheel UI feels dated in comparison with extra fashionable touchscreens. With dependable efficiency, correct prints, and robust TPU capabilities, it achieves print speeds as much as 320mm/s, prioritizing high quality. The Core One is notably quiet, averaging ~48dB, and maintains Prusa’s dedication to repairability, with reasonably priced, accessible elements resolving uncommon points like an ASA print failure. Priced at $949 (package) or $1,199 (assembled), the premium value is justified by its offline usability, open-source ethos, and sturdiness. Total, the Core One is a top-tier selection for these valuing high quality, repairability, and user-friendly design, regardless of minor drawbacks just like the dated UI.
