 +This was my first ever 3d print and I made some fairly obvious mistakes:
 +
 +   * Aligned a lot of the parts to be completely horizontal (result: resin doesn't drain properly)
 +   * Used automatic supports only (result: some of the small parts are slightly warped)
 +
 +In future, it's best if parts are angled away from the build plate and lcd at anything up to 45 degrees. In addition, smaller parts do need supports!

 +Most parts are looking pretty good - except the camera/fin (which has a warped bottom, rather than flat), and the base of the bust itself, which again is slightly bent, rather than flat. In hindsight those two parts should have been <del>affixed directly to the build plate</del> angled to allow the resin to drain, rather than <del>put on supports</del> flat which allowed it to pool on the horizontal surface.
 +
 +Some basic cleanup of the head, fin and face plate:

 +The last image, above, is compared to a [[:blog:models_rx78_2_v3|1/100 scale Master Grade RX-78-2 Gundam ver 3.0]] - so you can estimate the scale of the printed bust to be //around// 1/50 to 1/60 scale.

 +Mock up of the final piece, missing the neck part, of course:

 +==== Re-printed part ====
 +
 +**[Update July 10th 2021]** - Reprinted the failed neck connection part, played around with the orientation in the slicing software and added some more supports, as well as recalibrated the 0-position. It printed much better this time:
