Magic [Draft 02/03/2010]

[Reflecting back on this post is a little bittersweet.  2010 was an incredible time to be someone with a 3D printer at home.  I remember Forrest Higgs’ detailed website about how he built his mostly wooden 3D printer.  By my recollection, it was slow but accurate enough to make useable parts.  Back then it was possible to read literally every single word published on the topic of 3D printers in about 30 minutes once a week – and I did.  I read, and re-read, so many of Forrest’s posts leading up to and well after the purchase of my Cupcake.  While Forrest’s site is no more, it lives on at Archive.org.]

Since I know basically nothing about how the actual electrical components of my MakerBot work, the entire thing is essentially magic to me.  (OOooooh!  Shiny lights!)

One of the things that kept me from buying a MakerBot in the beginning was the thought of trying to solder surface mount components.  Admittedly, I wasn’t exactly a pro at soldering through hole components either, but the idea of soldering super tiny parts using a hot plate was certainly off-putting.  I know the MakerBot guys said it is pretty easy, but I certainly had my doubts.

One of my favorite projects to monitor is Forrest Higgs progress on his Tommelise.  His goal, as I understand from his blog, is to design/build a machine that could be built cheaply by a reasonably clever and motivated 12 year old.  While the suggested cost of building a RepRap Darwin/Mendel is somewhere in the $500-$750 range, Forrest suggests a Tommelise could be built for as little as $150.

The trade off is that the Tommelise uses a lot of wood in its construction (cheap, but not RepRappable “vitamin” part), uses linear stepper motors, uses through-hole components so it doesn’t benefit from the nifty wizbang bits you can get in surface mount components,  and prints slower than a RepRap.  But, I keep thinking back to the breadboard prototypes Forrest puts up on site.

Vouyerism

One of the interesting things about following along on other people’s MakerBot/RepRap/RepStrap blogs is seeing their workshop/work areas.  Some people have super organized, labeled boxes, and a clean clear uncluttered work space.  Others… are more like me.

  • Photos: I take photos of parts sitting on a sheet of white A4 paper that is being propped up against something.  With a light source it makes for a very clean photo.
  • Working on small parts: I have a long shallow wooden box – about 4′ x 8″ x 2″.  It’s small enough I can put it on nearly any surface, or even the floor.  It’s long enough to give me plenty of work space.  It’s shallow enough that it’s as easy as working on a regular surface – but has the short walls that prevent small pieces from rolling or falling away.
  • Working on large parts/Storage: I own a VERY large library card catalog (it’s a long story).  It’s about 6′ long, with 60 drawers on the front and another 60 on the back.  It stands about 4.5 feet tall and is about 3.5 feet deep.  It’s basically perfect for storing an enormous amount of small parts of … whatever.  I’m only using about three of the drawers so far for MakerBot parts.  It also serves as my large work surface.

Sanding

This part is probably unnecessary.  I’m not sanding down the surface of the wood parts because it is so thin the veneer would probably come right off.

However, there are some small tabs throughout the pieces where they were once attached to larger parts.  I’d rather do it now than after painting and then have to paint the sanded parts over again.
