Hi,
I have recently bought a chinese made 3D printer (http://www.come3d.com/en/c120n/) which works pretty good. I have made my first print with this model: www.thingiverse.com/thing:31313
It came out quite nicely. Then I started printing other, more detailed stuff, and there I have some issues. I have already tried leveling my printbed with the paper method and I believe it's not bad, but if you say that my print issues are still related to the unlevel printbed, I can try tweaking it further.
Generally it seems that using the red PLA works much better than the blue ABS that I have purchased from the same manufacturer (Come3D). Is PLA generally better or maybe it's just a coincidence or other factors?
I'm printing using ReplicatorG 40 with the profile Thing-O-Matic HBP Strepstruder MK7 (this is what the manufacturer suggested), Gcode settings Thing-O-Matic slicing defaults, parameters:
- raft
- no support material
- 10% infill
- layer height 0.3mm
- no of shells 1
- feedrates 30
- temperature 200 for PLA, 210 for ABS
- filament diameter 1.75
- extruder nozzle 0.4mm
Slicing engine Skeinforge 50. Printing now from S3G from SD card.
My concrete issues with pictures:
1. House printed with red PLA: [www.thingiverse.com]
- Here, apart from the fact that the printing has stopped at the end (ReplicatorG reported a communication error, I guess I will always have to use the SD card printing approach) is that under the windows, the material drops. It's probably not that bad and maybe support material could work (although on such fine detail, maybe I cannot remove the support material). See [attachment 17247 DSCN4187.JPG] and [attachment 17248 DSCN4186.JPG].
2. Blue ABS tower: [www.thingiverse.com] (scaled down to around 3cm height)
- This is where I have the most issues. The pictures speak for themselves. The lines are just bad. During extrusion it seemed that the extruder pushed down the previous layer it has printed, but at least it was touching it considerably. Before the print, I tried to calibrate the extruder to the center, and so it just touches the printbed. And the other print using PLA came out quite fine, using the same calibration coordinates and settings. So not sure if this is calibration related.
See [attachment 17251 DSCN4181.JPG], [attachment 17250 DSCN4182.JPG], [attachment 17249 DSCN4183.JPG].
3. Red PLA tower: [www.thingiverse.com]
- Here this is quite a good print, except there's a strange, but quite thin line imperfection on one of it's sides. Also the top part is not that high quality, but I can live with that, probably due to the fact that the model is scaled down.
See [attachment 17245 DSCN4179.JPG] and [attachment 17246 DSCN4178.JPG].
4. Red PLA tower (square): [www.thingiverse.com]
- Again the top is melted together. Scaled down to around 3 cm in height too.
See [attachment 17244 DSCN4185.JPG]
I would realy appreciate some pointers, as I'm a newbie to 3D printing. :)
Thanks and best wishes,
Bence
