Connex 500

Intro

Just before easter 2010 we installed a brand new 3D-printer, a connex 500 machine delivered by Signcom and manufactured by Objet Geometries. The printer itself is using polyjet technology, which means that it builds the model by applying layer by layer of thin liquid photopolymer on top of each other. Each layer is cured instantly by the use of UV lamps.

FAQ

Know-how

Material costs

  • Support material cost us slightly more than 1kr/g
  • Fullcure 720 cost us slightly less than 3kr/g
  • Vero and tango materials cost us around 3kr/g
  • Tangoplus materials cost slightly more than 4.5kr/g


Build material

  • Fullcure 720 is cheaper and more sturdy than the Vero materials. The downside by using this material is that is cannot be mixed with tango materials to obtain semi-softness.
  • Tango materials will break if stretched more a few times. The 40% stretch limit indicated in the brochures is not something that can be obtained multiple times without tearing.
  • Tango plus is more flexible than Tango materials, however stretching it to 200% multiple times will result in tearing.
  • Tango plus material will go back to its initial state very slowly, and is not suited to use as a rubber band.
  • Tango materals are suited for making coatings, and perhaps to be used for shock absorbing.

Support material

  • Support material is cheaper than any build material. The machine has options for filling solid blocks with support rather than build-material.
  • The machine does not build air gaps, all caveties in a model will be filled with support material.
  • The support material can generally be removed with the Krumm water-jet.
  • Persistent support material can be softened by putting the model into water. The support material will absorb water and break or loosen up somewhat after a few hours has passed, then it can be removed much easier using the waterjet or a brush.
  • The water jet is generally the best way of removing support
  • The support material can consist of build-material as well as fullcure 705. This amount of build material in the support can be adjusted in objet studio.
  • Note that the border between material and support will be a mix of the two components, as they mix somewhat before curing.
  • To achieve completely smooth surfaces in a model where there used to be support material- sanding will be needed.
  • At 1mm thickness, the vero materials may break easily- they will probably withstand the use of the waterjet, but they may also break thus caution is needed when removing support.
