Syringe Pump

Printing Syringe Pump Components

Print the following files with high infill density (we used 70%). The best orientation would be horizontally across. For example, the flange holder would be printed with the L shape on the printer bed.

The stl files are linked to the name of each component.

Name	Quantity	Drawing
Syringe Motor Mount	1
Syringe Displacer	1
Flange Holder	1
Syringe Hub Holder	1

Modifying Dimensions

If your syringe’s dimensions do not fit the model, use the Open SCAD files and export new stl models to print.

Download Open SCAD here.

Here are the links to the Open SCAD files you can use:

All the numbers in Open SCAD are in millimeters. Follow these steps:

Edit the dimensions in the SyringePumpConstants.scad file.
- plungerDiameter is the diameter of plunger flange.
- plungerThickness is the thickness of the plunger flange.
- plungerInnerDiameter is the diameter of the part of the plunger directly below the flange.
- barrelDiameter is the diameter of the barrel.
- barrelSlotThickness is the vertical thickness of the barrel flange.
- barrelSlotHeight is the total horizontal width of the barrel flange (use the shorter distance if the flange is asymmetrical).
- hubDiameter is the diameter of the narrower part of the syringe below the barrel.
Save the edited SyringePumpConstants.scad file.
Open each model you want to print, click the render button.
Export the rendered file as .stl.

Bath and Collector

Printing Bath Containers

For the coagulation bath and water bath, we used a resin printer so that the baths don’t leak. If you don’t have access to a resin printer you can waterproof the baths by coating or spraying them with watertight sealant.
