Some months ago, I was browsing on Amazon when I came across a printer from a company I had never heard of before. The company was called Weedo and the printer that I found was called the F192. The printer looked pretty awesome, with its acrylic doors that open from every side, touch screen interface, and dual extrusion capability. The only real dual extrusion I have played around with on my own, is a mixing typing with two filaments that go into a hotend with only one output. This machine on the other hand, has two extruders that both have their own hot ends.
I went ahead and reached out to Weedo for a unit to review and they agreed. Normally, I do not watch other’s reviews of machines that I know I will be reviewing. However, with this printer, I let my excitement get the best of me and I watched 3D Printing Professor’s video review of this printer. I am actually glad in this case that I did, because I learned that this machine uses a MakerBot style board and firmware like a FlashForge machines called XG3 instead of your standard GCode.
The 3D printer was delivered through Amazon’s delivery service and I was pretty shocked was left on my doorstep without a signature. The F192 3D printer came in a huge box and I needed help to get it through the front door. It seemed to be wrapped very well in a massive box that showed no damage. I unpacked the printer, cut all of the zipties and removed plastic bars that where installed to keep the hotend from sliding around while in transport. This is when I noticed that there had been some damage caused during shipping.
The F192 3D printer has acrylic panels on each side of the machine so you can see everything going on as well as open and access any part of the machine easily. One of the clips had broken during shipping. Also, the mount that held the cable chain to the printer’s frame had broken during transit. I let Weedo know about this and they apologized for this but did not offer right away to send replacement parts. I ended up later on 3D modeling and printing replacements out of PET-G.
I turned the machine on and was greeted by a happy gingle as the printer lit up with beautiful RGB LEDs as Weedo displayed on the touch screen. I went ahead and ran through the bed leveling process which is not automatic but is not manual. The machine probes three spots on the bed and tells you which to adjust until all three are completely level. It is a pretty simple and neet process that worked very well for me. I then went ahead and printed the tiny dual color test cube that turned out perfect, I was incredibly pleased.
Then it came time to slice my own file to print, which is where I ran into my first major roadblock. I loaded the files and installed the Cura for Weedo software that was on the included SD card. On one of my computers the software would not open at all, and on the other it would open but crash everytime I tried to output the sliced file. I could not figure out how to get the software to work and was frustrated that I could not use my regular Cura since this printer does not take standard GCode.
I looked at other slicer options that were able to export XG3 files but was not happy with the available choices. I then saw that Simplify3D was able to output this format. This slicer costs $150 but has been something I was interested in prior so this was enough to make me make the purchase. I was up for about 2-3 hours learning the new slicer and trying to get it to work with the printer. It was tough, mostly because when the X and Y axis home, the X axis needs to move to a certain location before homing the Z axis. I was able to copy over the starting script from Cura which allowed me to finally home the machine correctly. However, no matter what I did, I could not get the hotends to heat correctly and gave up on Simplify3d.
After doing some more digging into what I could do, I discovered another slicer from Weedo called Wiibuilder. This was a huge relief and I was finally able to slice both single and dual color prints with this slicer. This is where my experimenting with dual extrusion began. I sliced a dual color poison dart frog using a prime tower, but ran into problems when the tower fell over. I then went ahead and used a wipe wall or ooze shield and was blown away by what I woke up to the next day. The print turned out absolutely awesome and was a complete success.
After that print I tried a MatterHackers 3DPhil which had a little bit of color that ended up where it wasn’t supposed to be, but overall I was still very happy. I then tried to print a vase that was two color using a prime tower. It did not fall over but the stringing got so bad that I ended up canceling the print before completion. Weedo stated that the machine could use PVA water soluble support material so I was eager to test this. I had never printed with this material before myself so I was not expecting it to go very well.
Strange enough, I went ahead and went with the most difficult print that I could find, which was a gyro from Ultimaker. It is 5 crazy geometric round balls nested inside of eachother and had to be completed submerged in the PVA support material. I let this print while I was at work and came home to a mess, a beautiful mess. The PVA was very messy and incredibly stringy, but at its core, the print was nearly perfect. I removed the print, submerged it in water, and once I removed the PVA was left with this beautiful print. This is likely one of if not my favorite print that I have done to date.
After seeing this print, I was very satisfied with dual extrusion prints that had come off of this machine. I then decided I wanted to print in ABS, since this is a material I have not printed with in over a year. I had a few spools laying around and figured that this enclosed machine would be the perfect time to bust them out. I printed a Ketchy as well as a Two Face bust designed from Wekster, and was very happy with the print quality, they turned out awesome. Then I wanted to do some PLA printing since I still do a lot of printing in PLA. It did a fairly decent job on printing PLA but not on smaller portions or some of the details. There is no layer cooling for either of the extruders which is likely the culprit for this.
Since it was a direct drive machine, I wanted to print in some tpu and tpe materials. I ended up trying both, but did not have great luck. I had a clogging issue one time and had some of the filament get jammed inside. I had to disassemble the hotend to remove the filament that had gotten stuck in the gears. The main issue is that loading filament into this machine was a bit tricky for me. You have to get the angle just right when pushing the filament down which is pretty impossible to do with a flexible filament.
After going through some pretty heavy experimenting with this machine, I am confident in saying it was overall a good experience. The machine is built very well and is constructed of a metal frame that uses a pretty beefy ball screw for the z axis. Once you get past the software hurtle it is pretty much smooth sailing. The F192 was able to take nearly everything that I threw at it with a few exception that were likely the fault of the slicer. I do wish that the hotend could go above 235 to be able to print in PET-G and higher temperature materials but for dual PLA and ABS it feels like you are getting a lot of machine for the cost.
