The L1 printer requires a number of accessories to support operation. These include:
- Cassette cart
- Chiller
- Oxygen supply (oxygen concentrator or oxygen tank)

The L1 cassette cart is a Carbon accessory designed to safely transport and install the large printer cassette. It uses a mechanical foot pedal to lift or lower the cassette into position.
- The cassette cart is only designed for use with Carbon cassettes and should not be used for any other purpose.
The chiller removes excess heat from the coolant that is circulated through the L1 printer. This keeps the printer cool and functioning normally.
- Must be connected to the L1 printer through the coolant connections at the foot of the printer in the rear.
- 3rd party item.
- Supports up to 6 printers (60 Hz model).
- For more information, consult the manual

An external source of oxygen is necessary to supply the dead zone during printing. Customers can use an oxygen concentrator or oxygen tank.

Oxygen concentrator
- Mechanical device that actively pulls oxygen from the ambient air.
- Must be connected to the L1 printer through the oxygen inlet at the top of the printer.
- Can supply up to 10 printers.
- 3rd party item.
Oxygen tank
- Tanks of oxygen are available in many sizes.
- Oxygen tank must be sourced locally.
- L1 nominal flow is 20 mL/min while printing.
- Can be connected to multiple L1 printers.
- With typical printer use, a 55" tall, high pressure steel tank (49 L/1.73 ft3) should last 3-6 months.
- Transportation and storage is subject to local regulations.

A number of other accessories exist to support the L1 printer:
- L1 cassette hotel
- L1 platform hotel
