110V 1000W Lab Convection Oven, Horizontal Electric Blast Drying Oven with Intelligent Temperature Controller, RT+18°F～572°F, Laboratory Drying Box for Industrial, Schools, Research Institutes

Lab Oven I use this lab oven. Gets plenty hot, up to 300° C. Has a timer or can be set to run non-stop. Has a fan and a vent hole in the top. I set up a spool roller inside and printed a plug for the top vent that connects to PTFE tubing. I feed the filament straight from the oven into the printer and can keep it warm/dry while I print. It also works well for annealing parts after printing.
