Richard Gain recorded a video to show tricky process of removing the support material from complex 3d printed object which also shows the tools needed. The object is 3d printed chassis for micro battle robot.





The chassis went into this micro fight robot

Adam Kemp made this low cost extruder project from scratch made from aluminum and automotive glow spark as heat source. You will need to cut some aluminum parts, but the design looks solid.

From project description:

I love 3D printing, so I decided to build my own printer. After playing around with commercial machines like MakerBot’s Cupcake and Thing-O-Matic, it hit me that I could make my own for free, or very near it.

So, off I headed down the long and winding road to design and build a small 3D printer (or as my son likes to call it, the Toy Machine). After a great deal of dumpster diving, I scavenged enough stepper motors, linear rails, and drive belts for the mechanical parts, but I was stumped when it came to the heart of the printer: the extruder. The internet turned up a slew of fancy designs, but all possessed one design flaw: they required 3D printed parts, so you’d need to have a 3D printer to make a 3D printer!

My solution was to build this robust extruder using a handful of tools, one online parts order, and a trip to the auto-parts store. For a heater, it uses a $10 glow plug from a diesel engine, and it performs as well as commercially available extruders.

Mikey77 made a small 3d printable electronic circuit and created a detailed how-to guide on Instructables. It is made on a regular FFF DIY 3d printer (Replicator 2) shaped like network of grooves and holes in a printed board filled with DIY conductive glue which closes the electric circuit.

Here is detailed instruction video on how to use ceramic delta 3d printer by Jonathan Keep. It explains basic software operations with Repetier host, clay preparation, clay printing etc. Very interesting.




First post about this ceramic delta:

Made by hand! 0,4 mm carbide PCB drill bit and brass dome head nut ... fining the center with lack of vibration ... great work!

I would like to see it printing ...

Update 2:

he made a chocolate printing setup:

From video description:

Here is one of the many approaches to designing gears for 3D printing.
1) use Gear template maker to design a gear
2) export to a jpg file
3) use freeware wintopo to vectorize and save vector as a 3D dxf file
4) use a CAD program to import the 3D dxf and extrude surfaces
5) clean up with free netfab or send directly to 3D printer 

Notes:
This project explains how I go about making different types of gear profiles (different sizes, tooth number, addendum etc...).
The Gear Template Maker (GTM) shareware is a program that was designed for CNC or laser cutting of gear outlines but only generates a 2D dxf file. I wanted to get to a 3D dxf file that could be 3D printed on an Up!3D printer.
The steps that I use apply to sprocket gears, involute gears,rack and pinion gears.
The basic idea is to get from a jpeg image generated in GTM through freeware version of Wintopo to generate a 3D dxf file that you can extrude using any basic CAD program, then print on a 3D printer. The entire process should take under 3 minutes.

This video shows how to configure a sprocket gear that can be used with a Tamiya belt kit. See www/thingiverse.com project "Making gears".
