Experimenting with rafts and support material with ProtoPasta PC-ABS and S3D with truly awesome results. The easiest and cleanest support material removal I have ever used.
@Whosa_whatsis previously mentioned using this material with great support material results in his diagonal printing methods, which I have to second.
ProtoPasta ABS-PC printed on a Mendel 90 with an E3D-v6 at 290C on the nozzle and 130C on a UHU Stic coated bed. Sliced with Simplify 3D with pretty much the default settings.
