High-performance extrusion 3D bioprinter platform for gels

Chalmers Tekniska Högskola Aktiebolag

Description of goods

The item is a high-performance extrusion 3D bioprinter platform for gels.

Requirements specifications of goods/services

The purchase must include the following products/commitments/services:

1. An extrusion-based 3D bioprinter capable of handling bio-based gels. The bioprinter must include a pneumatic printhead for the printing of gels. The versatility of using bio-based gels must be documented through commercial or academic research paper examples.

2. The bioprinter must have a broad range of photocuring modules for crosslinking.

3. The bioprinter must be equipped with clean chamber technology, capable of high-performance particulate and microorganism filtering for sterile air flows and germicidal lamps in the printing area.

4. The bioprinter must have a heating/cooling print bed.

5. The bioprinter must have the option to be upgraded with exchangeable multiple printing heads for multimaterial bioprinting. The exchangeable printing heads must include inkjet, thermoplastic, pneumatic extrusion, syringe-based mechanical extrusion and photocuring. The commercial availability of such upgrades must be documented.

6. The bioprinter system should be capable of printing speeds that reduce the time cells spend in the printing environment.

6. The bioprinter unit must allow for direct use as a stand-alone unit without the need for additional hardware, like a laptop or a pressure source.

7. The bioprinter must have a compact design enabling benchtop printing.

8. Software for printing with perpetual license must be included.

9. The software system must accept STL file or G-code files.

10. Installation and on-site or online training must be included.

11. Shipping and handling must be included.

11. A 12 month warranty must be included.

Price

Price shall be submitted in SEK excluding VAT and include all related costs requested in this request for tender.

Agreement terms

The supplier must accept all agreement terms.

Tender submission

The tender must be received no later than 21-12-2021

The tender shall be valid until 31-01-2022.

Evaluation of tenders

The winning contract will be awarded to the supplier providing the rotational rheometer which satisfies all the tender requirements for the maximum price of 277’000 SEK. To be awarded, the supplier will be evaluated based on the Performance criteria below, which will be used to evaluate the precision of the system.

Performance criteria

1. 3D bioprinter with an established record (commercial and//or academic examples) for printing bio-based gels. [Y/N]

2. Capability to upgrade with exchangeable printing heads for multimaterial bioprinting: inkjet, thermoplastic, pneumatic extrusion, syringe-based mechanical extrusion and photocuring [Y/N]

3. XYZ movement resolution: 1 mm [Y/N]

4. Heating/cooling print bed temperature range: 4 – 65 °C [Y/N]

5. Photocuring modules for targeted protocoling with wavelengths of: 365, 405, 485, 520. [Y/N]

6. Clean chamber technology with high-efficiency particulate and microorganism filtering with up to 99.995% retaining capability [Y/N]

7. Equipped with germicidal lamps for purging the printing area of contaminants using automatic sterilization cycles. [Y/N]

Confidentiality and the freedom of information principle

After the procurement has been terminated the principle of public access to official records applies. This means that all documents related to the procurement process become public and may be disclosed to anyone who requests access to them. Exceptions may only be made if there is any specific reason to believe that the Tenderer may suffer damage if the information is disclosed.

If you have information that you feel is of such nature, your tender shall include precise details of which information should remain confidential, and how you would suffer damage in case of the public disclosure of this information. Chalmers will evaluate your request and determine whether confidentiality in accordance with Swedish law may be deemed to apply.
