Accessories

Iontips

Used for XY calibration, printing or simple as protection for transporting or storing the printing head.

Bottom view of consumable including cantilever

Side view of consumable incl. tip geometry

Consumable holder

Used for calibration and iontips gripping and dropping.

Warning

Use only A1, A3, C1 and C3 slots! Always store iontips back in their blister or in the holder rack mounted on a wellplate before removing the consumable holder from the printer.

Wellplate

Used to hold various liquids (water, electrolyte, etchant,…) for setup and cleaning purposes. The wellplate used must suit the wellplate defined in the software. To use other wellplates, their new plate definition must be defined.

Bubble drier device

Used integratively with the wellplate it allows to remove the bubble of water that forms around the iontip after the consumable has been immersed in deionized water.

The bubble drier device is composed of three elements:

• the bottom ring
• the top fitting with positioning features
• paper flapss

The paper flaps can be used multiple times as they are made out of 20mm diameter Whatman filters. To obtain two flaps rfom the disk:

1. fold the disk in half
2. cut about 1mm of paper from the straight edge in the same direction of the straight edge
3. The two obtained “halves” can be placed on the bottom ring.The notches on the bottom ring help placing correctly and maintaing the position while in use.
4. place the top fitting in the bottom ring until it bottoms out to keep the flaps in place.

Calibration plate

Used during the installation, calibration and maintenance step. Please store it properly to avoid dust deposition on the plate. The glass slide displays a 1*1mm ruler in the center used for various calibration procedures. The aluminum plate has a hole (not anodized) which is used in the XY stage calibration step. When placing the calibration plate in the printer (left port), make sure to push it at its maximum top left position to get consistent measurements.

Printing chamber

The CERES printing chamber holds the printing cell for electrochemical printing processes.

It consists of the following parts:

Base plate

Aluminum base plate with build-in locking and positioning mechanism

Cell Body

Teflon part provided with a rigid anodized aluminum ring at the bottom

Clamping Ring

Teflon part fitted with gold terminals to the chamber, a jumper connector and, a lemo plug to the XY stage sled

Counter Electrode

Graphite L shaped ring

Working Electrodes

The working electrode is composed by two graphite pieces: a connecting ring and base. The latter comes in 2 different dimension to accommodate different substrates dimension (15 mm x 15 mm or 25 mm x 25 mm)

Reference electrode

Teflon ring fitted with a inlayed Ag/AgCl wire

Substrate holders

Two teflon parts with differently sized cuts to fit different substrates dimension (15 mm x 15 mm or 25 mm x 25 mm)

Teflon spring

Teflon part shaped like a truncated cone

Sample exchange tool

Two custom sample exchange tools to be used with different substrates dimension (15 mm x 15 mm or 25 mm x 25 mm)

Sealing o-rings

A FKM 70 55.0x1.5 and a FKM 70 46.0x1.5 o-ring

To clean the carbon parts, Teflon parts and O-rings in contact with the electrolyte, washing with deionized water is usually sufficient if the same supporting electrolyte is used. For in-depth washing, please refer to the chamber cleaning procedures.

For precise instructions on how to assemble the printing chamber, please refer to the Prepare Printing Chamber SOP.

Spare sealing screws and O-rings

Spare parts are delivered with the system:

• noze O-rings (head side)
• consumable O-rings (iontip side)
• a spare sealing screw already assembled with a consumable O-ring.

Probe lever

A small steel needle used to open the grippers of the printing head and to release or grip consumables by hand during installation or maintenance steps.
