    That's a great print.
    What was your process for post printing cleaning up?
    I know the maker bot and other wire extrusion type printers have a problem leaving a noticeable layering effect.
    Did you use something like acetone to smooth out the surface and then sand it down?
    How much detail did you have to re-sculpt in by hand?
    if you have any pictures of the raw print and some of the clean up that would be very helpful to see.
    Thanks,

    Here is a shot of a small head straight out of the printer . It is the same size as the one in the shot with the other heads and a key for scale.
    The biggest clean up is getting the supports off and the build lines. Unfortunately there doesn't seem to be any solvent that you can brush over the surface to remove the build lines except for solvents that are too dangerous to work with. Acetone does a little but then leaves dry flakey patches.I have been sanding and using dental tools to clean up the prints. Also really valuable us using a soldering iron with a variable temperature setting. Many of the pieces that I have
    printed have had a problem when for some reason a couple of rows don't print. To save the print I pause the printer and with some scraps from previous printouts or just more of the PLA filament I basically weld it back together with the soldering iron. Then resume the print. Otherwise it will continue printing and after a while the top few layers fall off and the printer continues to spew out plastic which results in a big mess. Once the print is finished I will then carefully weld the seam on the surface and try and bring it back to what it should look like.
    The hat on the flesh colored Popeye had this happen several times. It took something like 8 hours to print and I didn't want to have to do it again so I welded it all back together and then added the threads that run horizontally across the hat. I used real thread and melted it into the printed hat. That took a while but I had to do so much welding and patching on that had that I lost the modeled threads.
    I painted the Popeye with Alkyd paints,a fast drying oil paint. many thin glazes, with a day in between glazes so that they dried. It does appear though, that I can scratch off the paint if not careful. The metal one was painted first with primer then gold spray paint then glazes of acrylic. I hope you can understand my answers.

    Thanks for the raw pictures.
    Your answers make sense to me.
    That's actually surprisingly better detail than I've seem from most maker bot prints.
    I think the more recent models seem to print better than the early DIY versions.
    We have one at the school where I teach. Which model do you have?

    The reason I asked about the acetone was from an old trick from my physical modeling days called Sprue-goo.
    For those that may not know you take the old plastic sprues form a model kit and put them in acetone.
    This melts it down till you get a almost elmers glue like stuff that can be used to fill in gaps on a model.
    I thought a similar trick might work with the maker bot filament to smooth over the surface.
    Some detail would be lost but that, maybe, could be re-sculpted back in.
    Thanks again for the info.

    Rick,

    the prints are spectacular!
    especially love the the hair details on the Wolfman.

    Wow thanks so much!
    Such great work,
    so cool!Best 3d print ever.(and clean up

    But i am stil curious about the model number of the printer u used,it seems to handle the fine details very well.

    Thanks again.

    You rocks! ;-) awesome job as always.

    Did you exaggerate the surface details before print it out?

    Would be great for the Pixologic guys create kind of 3D Printing Preview window, where may you can load different 3D Printing profiles (loading different printer settings or just selecting the brand from a drop menu...) and visualize how it's gonna look when is printed. I been using different kind of printers, resins, powder, and all of then have different results and is not just based on the microns you have or the material is been used, is bit more than that.

    Is just an idea but would be great pre-visualize our models for 3D printing purpose before send to the printer in order to have a chance to exaggerate or do last adjustments.

    Thanks
    Best

    To answer some of your questions:

    These were printed on a makerBot replicator2. There is a lot of post printing work cleaning up the prints and it took me quite a while to get up to speed with the makerbot mainly because I don't really know about this stuff. I finally got these results with a lot of trial and error,about a months worth. Most of the problems were like I said ,I don't know what I am doing. At first I tried printing models with millions of polys.It took forever to slice the model if at all. once I started decimating the ztools and using the 3d print exported plug in,I love you pixologic, things worked a lot better.

    The hair on the wolfman print was touched up a lot after the print using a soldering iron. In fact all of the hair on his chest was added after printing. I eliminated the subtool for the chest hair before printing because of the large polycount of the model.

    I don't really exaggerate the details before printing the details were pretty exaggerated on the original model. The prints have a lot less details than the original Ztools.

    Thanks for looking

    I can attest to that Rick. I have printed several models that have required a fair amount of clean up. I use many of the techniques you do, plus another I learned elsewhere and that is to feed filament into a glue gun style hot end. This allows me to flow plastic into holes and other areas that require extra plastic. I have also used the technique mentioned earlier with an ABS slurry. If you ever make it up to San Luis Obispo, please come on by ( httpe://slo3dcreators.com) And as you have heard many times before, you have been inspiration to me, and I have admired your work over the last few decades. Yep, knew of you when the Ackermonster was publishing "Famous Monster of Filmland."
