Its reliability, print consistency, and future-proofing make it a superior long-term investment, especially for professional use.
So, while there’s still the distinctive maker look to the printer, it is becoming increasingly refined.
A new optional GPIO board enables makers to develop their accessories and enhancements.
Although upgrades from the MK4 to the MK4S may seem slight, they significantly increase performance and speed.
Despite continuous improvements, the machine’s overall look and styling have remained reassuringly similar.
The main upright structure, lead screws, and associated mechanisms remain largely unchanged from the MK4.
This system features a high-pressure fan, which operates most of the time to maintain optimal cooling.
The high-flow nozzle enables the printer to handle the increased print speeds with the standard high-flow 0.4mm nozzle installed.
One of the common issues faced with Original PRUSA machines is connecting the PRUSA slicer wirelessly to the printer.
While many other companies have streamlined this process, PRUSA’s approach previously couldn’t have been more complex.
The MK4S addresses this with a native app setup, making the connection process easier.
Aesthetically, the MK4S has few changes apart from slight variations in the fan design.
Finally, two additional optional parts can be added to the MK4S if required.
The challenge remains in conveying these benefits to potential buyers in a competitive market.
Well, almost; just load the filament, and you’re good to go.
When it comes to setup, this is one of the quickest and easiest printers we’ve ever used.
When it comes to print speed, the MK4S is fast, though not noticeably so at first.
The PRUSA MK4S is quiet and understated, producing immaculate, high-quality prints without the noise and fuss.
The quality of the prints was again excellent.
In isolation, all the test prints seem to confirm these attributes.
Looking at the following three models really proved the point.
The obvious winner here is the PRUSA, with the other two printers struggling to produce usable prints.
There were some slight overhang issues for the Bambu, but it was still a very passable result.
However, it’s difficult not to draw comparisons with these machines.
Running all printers consistently with the same models showed where the PRUSA stands out: complete reliability.
The PRUSA produced all ten prints of exceptional quality, as did the K1C.
The P1P, which is ageing, failed to print on this occasion but is usually quite consistent.
The Original PRUSA MK4S is considerably faster than the MK4over 50% faster.
This is surprising, given that it’s essentially a very similar machine with almost the same parts.
Its durability, upgradability, and ease of repair make it a standout option for serious users.
The MK4S delivers consistent, high-quality prints without the hassle of frequent maintenance or unexpected issues.
If something does go wrong, spare parts and community support will ensure that any downtime is minimal.
One important consideration is that the MK4S, like previous PRUSA models, is an open-frame machine.
The MK4S is highly adaptable for various uses, with expansion opportunities through the new GPIO board.
