I purchased this 3D printer from RioGrande in 2020 for $3,500 and have only used it twice. It has been kept clean and stored in its original box. It is an incredible printer and I wish I had more projects for it, but only used it for the one. 

Desktop sized 3D printer utilizing LFS (Low Force Stereolithography). It measures 15.9" × 14.8" × 20.9" and weighs 50lbs. It has a maximum build volume of 5.7 x 5.7 x 7.9 in. The XY resolution is 25 microns and the layer thickness is 25 - 300 microns (.001" – .012"). It uses one 250 mW laser at 405 nm. Features a 5.5" touch screen. In addition to the printer, there is a Formlabs Finishing Kit, which includes:

- Finishing tray

- Scrapper

- Rinse basket

- Squeeze bottle

- Flush Cutters

- Tweezers

- Non-Abrasive, lint free pec pad wipes

- Removal tool

- Removal jig

Highly recommend getting good quality disposable nitrile gloves, as well as isopropyl alcohol and paper towels--which is an approved cleaner for these machines.
