I'm not sure what are the advantages or specifications but I like the inverse looks of it :-) Print results also look solid. It should be very cheap since it uses fishing line, rubber bands and other low cost materials.
Nice work Jeff!
Delta-T in action:
This new 3D printer is a delta-type design but with a flying carriage suspended by 6 strings that wind up directly onto the motor shafts. No rails, bearings, belts, pulleys or lead screws.You can follow the development and get much more information at:
This new version uses a Bowden-type extruder and a single spring-loaded tension post to keep the strings in tension. Still more work to do, but it's coming along.
