Playing around with 3D printers can be a lot of fun, but your prints don’t always come out right. Fixer3D is a handy pen that lets you fix your prints. It lets you control the amount of resin extruded with a programmable syringe pump. You can use the integrated UV LED light to finish the job.
The Fixer works on any UV curable 3D printing material. It can be used on prints from various 3D printers. You get 3 buttons to control the movement of the syringe and activate the UV light. More information is available here.
