3D Printing Filament Guideline

NCSU College of Design;
3D Printing Filament Guideline

Pricing from the NCSU Design IT Lab is available online if you are going to use the Dimension, FormLab or Mojo printers instead of providing a roll or if you want to use what we have on hand; this has been an option made available for graduate students, students registered in sponsored studio/projects and students doing independent-study around 3D printingtechnology/manufacturing within the College of Design.
Bring us your .stl/.obj file on a thumbdrive or email it to us and we’ll run the .STL file through some software (Nettfab Pro/Simplify3D) and analyze the slicing setup to let you know how much material it will use and how long it will take to print… Nettfab Basic is available on all the lab machines if you are comfortable with analyzing your .stl model by yourself.
Ideally Bulk roll in PLA or PLA+; 1.75 mm Diameter
NOT 3mm; none of the 3D printers we have on hand support 3mm filament.
Hunt Library and DH Hill both have MakerSpaces; however they support 3mm filament only and have those rolls on sale for purchase…  I believe Engineering has “The Garage” that is available for student use as well and they have a mix of 3D printing resources that might include 1.75mm filament.
With the Fusion3 and Replicator 2, we have been primarily using PLA… 
We can run solid colors, translucent/clear colors without too much issue – Translucent PLA on the Fusion3 is tricky since it is a bit more brittle it is prone to snapping during feed and extractions while printing.  Dual color printing is available but there are some extra steps on setup and front-end design to get simultaneous dual colors within a single model correctly. We can run ABS/1.75mm in bulk roll but only on the Replicator 2X, it’s possible to print ABS on the Fusion3 but we don’t recommend it.
We have run some ‘exotic’ filament with varied success: 
> Bamboo, brass/gold 
 – these tend to be more expensive and are usually sold in 1/2kg rolls.
>  Semiflex (flexible) and MakeShaper TPU
(not NinjaFlex, it’s way to flexible and too much trouble – prone to jams);
> Nylon/Carbon; some extra steps involved but it’s possible, see Fusion3’s website for qualified material available for use with the printer
Looking online, you can find prices for bulk roll filament between $20-40 for a 700g – 1kg roll.  Amazon has student subscription Prime plan available w/2 day shipping…
