I recently installed Ultimaker’s Extrusion Upgrade Kit on my Ultimaker 2, upgrading it to an Ultimaker 2+. I couldn’t be happier with the results! It’s like a whole new 3D printer!
I’ve been using the Ultimaker 2 for a couple of years now, and I was very happy with the printer overall. Out of all the desktop 3D printers I’ve tested, the Ultimaker 2 stood out as one of the best available. However, I occasionally would run into issues with the feeder mechanism. Sometimes, the filament would slip or the feeder would grind into the filament. This would sometimes lead to failed prints. I noticed this problem especially on prints with heavy retractions.
As an example, check out the photo below. I tried printing this on my Ultimaker 2, before installing the upgrade kit, and the print failed about half-way through. When it got to the part with all those small arches, it had too many retractions for the printer to handle. The filament was ground down by the feeder mechanism, leading to an “air print”.
After installing the Extrusion Upgrade Kit, this was the first print I tried, and it worked flawlessly! Since then, I’ve printed all sorts of things, with almost no failed prints. The difference the upgrade kit made is very noticeable.
The Ultimaker Extrusion Upgrade Kit retails for $395 in the USA, and each kit includes the following:
