Reservoir Heads is how we print (also known as Direct Ink Writing or Robocasting) with fluid or emulsified (non-filament-based) materials which are deposited at, above, or below room temperature, with or without UV Crosslinking.

Nordson and ViscoTec Heads

caption
Some customers have requested that we configure our equipment in such a way that heads from other companies like the Nordson Ultimus V heads or one of the Viscotec Vipro heads.

Yes, Hyrel equipment can accommodate these and other print heads with just a little custom code and a special tool holder. Please contact us if you have any questions at all.

Materials for Reservoir Heads

Reservoir Heads 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 OF ANY SIZE.

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.

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.

Reservoir Heads

Ambient or sub-ambient deposition is available through the following Reservoir-based heads:

Heated deposition is available through the following Reservoir-based heads:

EMO-Type Head Comparison
Temperature > 20°C < Ambient Ambient Up to 50°C Up to 90°C Up to 180°C Up to 270°C
Crosslinking
Optional
RSD-30 EMO-25
SDS-5, -10,
SDS-30, -60
SMH-2
HSD-30 HSD-10
VOL-25
KRA-15
KR2-15
TAM-15

Note, RSD-30 will take you about 20C below ambient.

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
KR2: Krakatoa v2: a more robust KRA head with a double gasketed plunger hotter, more viscous Emulsifiables - Very High Viscosity
TAM: Tambora: Heated (up to 270°C) Emulsifiables - High Viscosity
SDS: Syringe Dispensing System (uses disposable plastic syringes at room temperature) - Low Viscosity
HSD: Heated (formerly Volcanic) Syringe Dispensing System - Low to Medium Viscosity
RSD: Refrigerated 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
