Hello.
I am just starting out learning how to print with a 3d printer. We have a Wanhao Duplicator 4S in our office but none of us is really proffesionally trained to use it. We leveld the building plate and set the temperature for ABS filament to 220 degrees celsius (surface to 110 degrees). But when we try printing larger flat surfaces we get results like the one in the attached image. Is there anything we can do to fix this?
What type of surface are you printing on to?
It looks to be under extrusion. This can be caused by a few factors:
1. Raise your temperature, the material isn’t hot enough so the nozzle can not extrude enough material. 220 does seem a little cold for ABS, try 245 ish.
2. Change your material
3. Look at your PID settings
4. Look at extrusion rates in your software. Look at the the extrusion multiplier 1= 100% extrusion we have our printers at 0.93 maybe look at increase this figure.
3D printing does require a fair bit of trial and error, there is unfortunately no figures which will suit every printer, just try and have fun with it.
I highly agree that 220c is way too low for ABS, check the manufaturer’s temperature recommendation range and start from the middle of the range, the increase or decrease 5c to 10c until u get the correct results. Also check if your build plate is too close to the nozzle, your print seems to be a bit thin.

Going by the photo I’d almost certain say your build plate is too high, try lowering a little. Also as mentioned id up the temp for ABS.
With the wanhao after I’ve done paper levelling, I still normally watch the first layer and adjust the bed while its printing in the event the build plate is too high or low.
Best to set a slow extrusion speed for the 1st layer as it allows better adhesion to the bed, and also gives you time to tweak the bed if needs be.
