Water soluble and break away support material for 3D printing from E3D!

Breakaway AND Soluble Support:
Print any shape, inside and out, with support that dissolves in tap water!

Perfect Pairings:
Scaffold is developed for ideal adhesion to spoolWorks Edge, PLA, and FleXD.

Print the Unprintable:
Achieve incredible results and complex geometries with your desktop 3D printer.

Scaffold is a water-soluble and break-away support filament that actually works.

Scaffold offers total design freedom, helping you to create complex geometries and complete functioning mechanisms in a single print (with no worries about overhangs!). Part of E3D’s spoolWorks range, Scaffold works best with our Edge and PLA filaments.


• Can be broken away or dissolved from prints in normal tap water
• PVA/PVOH-based but easy to print with low viscosity
• Exhaustively tested for exceptional quality
• Lower heat degradation and easily purged from nozzles
• Designed for perfect compatibility with spoolWorks Edge
• Shipped in a re-sealable bag with desiccant for exceptional dryness

Additional improvements:

  • Scaffold adheres well to Edge, PLA, nylon, PET, and co-polyesters
  • Melt flow vastly improved compared to conventional PVA
  • Resistance to cross-linking considerably increased
  • If cross-linked the material forms a not fully solid (more paste-like) material that can usually still be purged
  • Less susceptible to moisture absorption, comparable to Nylon
  • Supplied in a nice resealable bag with desiccant for storage and use
Material Soluble Breakaway Notes
Edge Yes Yes Optimized pairing
PLA Yes Yes Very usable, good for large parts
Nylon Yes No Extremely strong adhesion prevents breakaway but resists warp
TPU Flexibles Yes Yes Flexibility provides very satisfying peel-away
PET/Co-polyester Yes Yes Usable, but with reduced adhesion
ABS No No Does not adhere

Removing Scaffold

  1. Remove the print from the Bed
  2. Break away as much as is possible
  3. Leave submerged in water to soak for ~60 minutes
  4. Flush out the part and clean off as much as you can
  5. Soak for a further 2 hours or overnight
  6. Clean off the remaining Scaffold with scourer pads or scrubbing brushes (for easily accessible areas) bottle brushes (for small openings)
  7. Dry the part - take note that there may be some water incursion into the model from soaking that can leak out over time

Very long dwelling in a hot nozzle should still be avoided (it would be great if slicers could help in this regard by cooling down inactive nozzles)

Moisture? If in doubt, dry it out on a heated bed at 45C

Cautionary notes and advice

• You will need to create specific slicer settings to make the best of Scaffold.
• Scaffold needs to be kept dry, use the supplied resealable bag, or even better use this specially designed in-bag spool holder.
• Scaffold will degrade if kept for extended periods in a hot nozzle. Do not allow Scaffold to rest in the nozzle at temperature or you risk clogging and damaging the nozzle.
• Please read the documentation in order to use Scaffold at it's full potential

Note: All 3D printers are unique so adjust settings to taste!
