Reservoir Heads
Cold Flow is our term for fluid or emulsified (non-filament-based) materials which are deposited at room temperature, with or without UV Crosslinking.
Warm Flow is our term for fluid or emulsified (non-filament-based) materials which are deposited at elevated temperatures, with or without UV Crosslinking.
Materials for Cold and Warm Flow
Cold and Warm Flow heads are for printing as follows:
- With pastes, gels, emulsifiables or waxes.
- At room or elevated temperatures.
- With or without UV Crosslining.
- With Hyrel Nozzles (1.5mm, 2mm) or Luer Tips.
The following materials can be printed from Cold Flow heads. Note that more viscous materials may not be suitable for plastic syringes or smaller luer tips.
- 3P Quick Cure Clay
- Adhesives
- Clay, Generic
- Epoxy, Two-part
- Fimo
- Glue
- Kato
- Metal Clay, including Precious Metal Clay (PMC)
- Modeling Clay
- PEG PolyEthylene Glycol
- Porcelain
- Plasticine
- Play-Doh
- Resins
- RTV Silicone
- Sculpey
- Sugru
The following materials can be printed from Warm Flow heads. Note that more viscous materials may not be suitable for plastic syringes or smaller luer tips, or may print more easily at higher temperatures.
Heads for Cold and Warm Flow
Cold Flow is available through the following heads:
| Temperature | Ambient | Up to 75°C | Up to 100°C | Up to 150°C |
|---|---|---|---|---|
| No Crosslinking | EMO-25 SDS-5, -10, -30, -60 SMH-2 |
VSD-30 | VOL-25 | KRA-15 KR2-15 |
| With Crosslinking | COD-25 CSD-5, -10, -30, -60 |
VCS-30 | VCD-25 | KCD-15 KC2-15 |
So, what do these goofy designations actually stand for?
- EMO: Emulsifiables at Room Temperature - Low to Medium Viscosity
- COD: Emulsifiables T Room Temperature with Crosslink On Demand - Low to Medium Viscosity
- VOL: Volcano: Heated (up to 100°C) Emulsifiables - Low to Medium Viscosity
- VCD: Volcanic Crosslink on Demand - Low to Medium Viscosity
- KRA: Krakatoa: Heated (up to 150°C) Emulsifiables - High Viscosity
- KCD: Krakatoic Crosslink on Demand - High Viscosity
- KR2: Krakatoa v2: a more robust KRA head with a double gasketed plunger hotter, more viscous Emulsifiables - Very High Viscosity
- KC2: Krakatoic Crosslink v2; KR2 with Crosslink - Very High Viscosity
- SDS: Syringe Dispensing System (uses disposable plastic syringes at room temperature) - Low Viscosity
- CSD: Crosslinking Syringe Dispensing System - Low to Medium Viscosity
- VSD: Volcanic Syringe Dispensing System - Low to Medium Viscosity
- CVS: Crosslinking Volcanic Syringe Dispensing System - Low to Medium Viscosity
- DSD: Dual Syringe Dispenser, dispensing two-part mixtures at a fixed ratio - Low to Medium Viscosity
- SMH: Static Mixing Head, blending your ratio of material through a baffled nozzle - Low to Medium Viscosity
As of Nov 2016, the latest firmware is 32V, included with Repetrel 2.828.

Settings for Cold and Warm Flow Heads
Some settings for the EMO-Type heads (like temperature, prime/unprime values) will vary, depending on what material you are printing with. Nozzle diameter should accurately reflect what nozzle you have loaded (1.6mm is default) AND what path width you sliced for. Temperature commands will be ignored by heads with no temperature control. Having said that, here are our default shipping settings:
