Sample Grinder Cone Adaptor

Description

Adapter cone for a Foss CT 293 Cyclotec impeller abrasive ring grinder. This funnel is used for faster sample processing and replaces the proprietary glass jar provided with the machine.

Steps to reproduce

Manufacturing Instructions 1. Acquire proper 3D files In STL format on Mendelay. 2. Obtain proper materials and equipment. For this example an SLA (Stereolithography) Printer and Form Labs "BioMed Clear" resin. This resin was chosen because of the properties listed, high melting temp, high impact resistance, low flexibility, can be sterilized, translucence, and bio-compatibility. 3. Input STL file into a slicer to format the document into something with supports in an orientation that the printer can use (we used Form Labs 3D slicer). 4. Within the slicing software, rotate the cone model so that the narrow opening is towards the build plate of the printer for best support removal later on. 5. Use the smallest layer setting possible. 6. Select the smallest raft size in the slicer software to reduce material waste. In this example, we selected mini rafts in settings. 7. Save the updated file to the computer. This step will change the file format from the original format to an STL with supports. 8. Upload the formatted file to the 3D Printer. Most printers require the user to select a file that has been uploaded to the printer in order to execute the job. 9. Print the grinder cone using the print function of the specific printer selected. 10. Once the print has been completed, remove the cone from the supports. 11. Submerge and soak in 99% isopropyl alcohol for a minimum of 15 minutes. No stirring is required. 12. Wipe down the outside of the print with a paper towel soaked in 99% isopropyl alcohol until there are no drips or excess resin. 13. Put the fresh print in either a UV curing box or UV sterilizer for at least an hour or until fully cured and no longer tacky at room temperature. 14. Leave fresh print in direct sunlight for 8 hours to off gas and cure. This product may need up to 48 hours to fully harden before it can be put in an autoclave. This product can NOT over-cure.
