Digital Machines - A practical overview

Contour model - 1:1000 - 900x600x50mm

FDM printer ★

  • It is a rather large model. It would have to be split into multiple parts
  • There are many flat parts which can easily be represented with sheet material
  • It would take a long time to print
  • If one is working with a 2D file would have to be modelled in 3d in a modelling software

Zund Cutter ★★★★

  • Layers could easily be produced from sheet material
  • The file required for cutting can be produced in 2D
  • No burn marks
  • May struggles with some of the tight details
  • Would have to be made from card

Laser Cutter ★★★★★

  • Layers can easily be produced from sheet material
  • One could easily work in 2d to produce the cut files
  • Has burnt edges.
  • Would be able to cut all of the tight corners and details
  • Could be made from Card, Airplane ply, wood Veneer or Acrylic

Manual Method (Cardboard and a knife) ★

  • It would take an extremely long time to produce something of this complexity by hand
  • Would require a massive amount of skill and patience.
  • Is possible but not recommended if there are digital cutters available.

Landscape model 1:2000 - 350x350x130mm

FDM Printer ★★★★

  • Some complex 3-dimensional geometry with double curvature, which makes sense to 3D print.
  • The 3D model would have to be split in 4 pieces which could work. (Only 2 split lines)
  • The ‘spiral vase’ method could be used to reduce time

Zünd Cutter  ★

  • The form is too organic and is made up of mostly double curved surfaces. Would be make very little sense to produce this on the Zünd.
  • Would only make sense to use the cut pieces to assist with another manual method in clay by creating templates or an internal armature.

Laser Cutter ★

  • The form is too organic and is made up of mostly double curved surfaces. Would be make very little sense to produce this on the laser.
  • Would only make sense to use the cut pieces to assist with another manual method in clay by creating templates or an internal armature.

Manual Method (Clay sculpting) ★★★

  • If perfect precision and accuracy isn’t of high importance, then this could be a very quick and effective solution.
  • Some templates or internal structure could be used to help by giving some more accuracy to the model.
  • A nice idea would be to produce the negative and pour in plaster for a more permanent model.

Small Context building 1:500 - 192x118x48mm

FDM printer ★★★★

  • FDM printers perform rather well producing small box like shapes
  • I would take a couple of hours to pint but a rather minimal amount of setup time
  • Could be clad in a thin material afterward or spray finished

Zund Cutter ★★

  • Would have to consider the construction method and redraw in 2D before cutting.
  • Requires some assembly

Laser Cutter ★★

  • Would have to consider the construction method and redraw in 2D before cutting.
  • Requires some assembly
  • Would have burnt edges

Manual method (Bandsaw and Disc sander) ★★★★

  • Most material options
  • Easier to sand the individual pieces before assembly. Would be able to achieve a very high-quality finish
  • Could be clad in paper or card afterwards. 

Facade 1:50 - 252x324x8mm

FDM-Printer ★

  • Not ideal for large flat pieces as it’s prone to warping.
  • Not the nicest quality finish for something of that size. 
  • Too large for the printer to be printed in one piece.

Zünd Cutter ★★★★★

  • Would work very well as the elements could be broken down into layers and stacked.

Laser Cutter ★★★★★

  • Would work very well as the elements could be broken down into layers and stacked.

Manual method (cardboard and Knife) ★★

  • Would take rather a lot of time
  • If one has access to a digital cutter, it makes little sense to do this by hand and there are parts with internal cut-outs for the windows.
  • The strips under the windows however could quite easily be produced on the guillotine.

Structural truss 1:200 500 x 40 x 35mm

FDM printer ★★

  • Structure not too suitable for FDM printing as the profiles are rather thin. Would work for SLS or SLA but would be very expensive to produce at this scale. 
  • Too large to fit on the 3d printers at the Raplab
  • As these parts could easily be produced on a digital cutter there is no reason to print these

Zund Cutter ★★

  • Would maybe struggle a bit with the small details
  • Would slightly overcut in the corners making them very weak

Laser Cutter ★★★★★

  • The laser would have no problem replicating something with these intricacies 
  • There would be some assembly required

Manual method ★★ (wooden sticks)

  • Would take a lot of time and effort to produce something rather fragile.
