Hi! I'm Jaeheon Shim, a computer programmer and technology enthusiast who lives in Columbus, Indiana. I like contributing to open-source development projects on GitHub, working on my own web-based applications, and writing articles on my blog Learn The Technology. In my free time, I manage CAMEO's public website and provide free tech assistance to friends and family :).
So yes, the Prusa finally arrived! I have had it and printed with it for a while now, and it has definitely met my needs. Before I spoil it any further, here are a few pictures I took upon unboxing the printer.
It took me 15 hours in total to assemble. Some of the plastic pieces broke during assembly, but they were easy to glue together with strong superglue. This should not be a problem, but if it becomes one, I can replace the part easily. Most of the non-metal hardware on the printer is 3D printed itself, and I can just use another printer to print the broken part. This leads me into another reason this printer is so great:
All 3D printers made by Josef Prusa to date are open source. This means that I could take the design for the Prusa I3 MK2, and modify it to fit my needs. Then, I could sell the modified version of the printer to other people who need that modification, and I would be able to make full profit off of the sale. Making a product open source is risky, and I am glad that Josef took that risk to make this printer extra great for us.
I could not write an article about this printer without mentioning the mesh bed leveling, which is basically what I call Auto Calibration. It does this by using a calibration probe, which is a rarely found feature on 3D printers. Although the process is not fully automatic (You will have to fine tune some settings), it saves a lot of time, and reduces the amount of failed prints.
By the time I wrote this article, another Prusa printer had come out: the MK3. I hope I can review one of those soon.
Most 3D printers have some sort of special surface on which the model is printed. Whether it be BuildTak, glass, or just painters tape, many makers try to increase adhesion on these surfaces to prevent warping and failed prints. The Prusa I3 Mk2 has an advanced PEI sheet, which eliminates the need for the use of blue tape or kapton tape. If prints are warping, all you need to do is add some glue from a clear glue stick and print away.
This is probably one of the best printers I will ever print with. I have only had a couple failed prints, and am excited to keep printing. Also, I have just decided to start a 3D Printing series on the blog, because 3D printing is one of my passions.
Also, be sure to follow jaeheon_shim on Instagram. This is my official account for public notice now, and I will be posting tech related posts on there!
And finally, I apologize for the inconsistent posting over the past few weeks. I have been sick and busy, and I will get my blog up and running again, with a steady stream of content.
