K8400 - Every beginner is an professional with this printer

the k8400 is a verry good printer. For the price of 600 dollar is this perfect for your first printer but even a verry good printer for everyone! In the beginning i had troubles woth the prints but with teperature calibration, it was solved. After 100 prints i changed the printhead by an e3d-v6 and now my prints are mostly perfect. The instructions to build and to use the software are very good. And a big forum with all the answers on our questions. My experience with the priner: the one you need.

Velleman K8200

Because my printer (K8200) was not in your list, I had chosen the K8400.

It's fun to assemble the K8200 yourself at low cost.

The K8200 has 1 extruder, the printbed moves.

The main problem was the printbed, which I solved by using an acryl plate 200x200x3 mm.

Now it works perfect.

Being an architect, I use the printer for scalemodels of my work.

The poor man's Ultimaker 2

This kit comes with a ridiculous amount of parts to assemble, and the assembly manual is online only, if you are brave enough to print it, it gives you a confusing pile of paper. Once you get past the assembly and calibration, I suggest you do 5 test prints with low expectations before getting serious prints done. The overall quality is the best value in it's price range, I compared it to the Ultimaker 2 and got very similar results, I definitely recommend. I work with 2 of them and am building a full custom one. PS: The initial kit can be modded, which is the strong point of this printer. Give it A month before giving up on it.

working god if you put the time to it hard to aline

I would recommend this printer, if you have the time for it they are many pieces to assemble. and to get the print head to slide easily take their time good and affordable machine when everything works

Print time

It is a good printer, but most prints take forever to print. So if you have time to sit next to the printer to ensure your print does not get jammed halve way and get a mes and wast of material the next morning. Could do with heated bed

Good printer

I've been using a Makerbot 2x for 4 years and decided to get one of my own. The Vertex is a real good printer, excellent value. Buiding the printer is easy, fine tuning might be necessary and requires some skills.  The main drawback is the lack of heated bed. I could not leave without it !

Good printer for the money

My first 3D printer,  and it works great out of the box with PLA.

I have modded mine with a 24v heated bed, e3d v6 hotends. And SPI controlled TMC2130 stepper drivers for quite operation :)

Pros: Dual extruder Great community Easy  to mod Sturdy design

Cons: No heated bed No all-metal hotends Vibrations from z-axis lead screw makes lots of noise All of these can be fixed though

Its is low cost, so don't expect results from an expensive one

The Printer is mainly well designed. A problem is the head.The nozzle is well cooled, but the upper part isn't which has as result that the filament will get stuck in it and burn. I replaced the heads (I have two) by E3D heads, but I didn't test yet. In addition I replaced the cooling by self made ones (made with formlabs form2). In addition, I printed another dual head mount ( Another interesting addon is the octopi (
