These printers are precision machines our lab primarily uses for high quality prints that will be tested in wind tunnel. 


The F170 has a 10 inch in width by 10 inch in length by 10 inch in height build volume. It is important to remember that the lower .125 inch of every print is used for support based build plate leveling, and as a result the largest prints can have a max height of 9.875 inches in height.  


The F370 has a 14 inch in width by 10 inch in length by 14 inch in height build volume. It is important to remember that the lower .125 inch of every print is used for support based build plate leveling, and as a result the largest prints can have a max height of 13.875 inches in height.


The F123 series use proprietary materials provided by Stratasys.


Model Material ABS-M30 (attached) 

Model Material ASA (attached) 

Model Material PLA (attached) 


Support material SR-30


The FX70 printers have the following print options.


4 different resolutions: 

  • .127 mm (.005 in)
  • .178 mm (.007 in)
  • .254 mm (.010 in) (PLA only)
  • .330 mm (.013 in) 


3 difference infill options 

  • Solid (parts is 100% dense) 
  • Sparse high density 
  • Sparse low density 

Please note that the sparse options are different depending on layer resolution, meaning that a part with a resolution of .254mm printed using sparse high density will have a different total density then a part printed at .330mm using the same infill option. A visual representation of this is available in the display cabinet of the RPL.


ABS Material Cost (ABS M30)

The ABS material for the FX70 cost 2.033 $/in3 however due to slight losses in the printer purging its head and other operations, use 2.5 $/in3 when estimating model cost. Note that models that need to be solid will use this much material, however models that are only for display purposes or can otherwise be printed hollow will not use as much material.


PC-ABS Material Cost (PC-ABS)

The PC-ABS material for the FX70 cost 2.3 $/in3 however due to slight losses in the printer purging its head and other operations, use 2.75 $/in3 when estimating model cost. Note that models that need to be solid will use this much material, however models that are only for display purposes or can otherwise be printed hollow will not use as much material.


ASA Material Cost (ASA)

The ASA material for the FX70 cost 2.188 $/in3 however due to slight losses in the printer purging its head and other operations, use 2.6 $/in3 when estimating model cost. Note that models that need to be solid will use this much material, however models that are only for display purposes or can otherwise be printed hollow will not use as much material.


Support Material Cost (SR 30)

The Support material for the FX70 cost 3.033 $/in3. It is important to note that parts with large overhangs and complicated geometries will use more support material and thus are more expensive. Also note that airfoils due to how thin they often are printed with a lot of support material to keep them from falling over during printing.


General cost

As a general rule, take the volume of your model and multiply it by 5$/in3. This will give a good estimate of cost for the parts to be printed.


F170 printers have the ability to support all overhangs with a separate support material. No special consideration is needed when modeling to accommodate the support.


Some printers require a flat surface on a model as a base. Due to the support material this is not necessary on the F170 printers. This allows you to print odd shapes (ex: sphere).
