3D printer update: Lulzbot.

I’m optimistic that their brand-new Lulzbot Mini – – coming out in February – – will overcome the filament feed complications I’ve familiar with the TAZ 4, and I shall of course purchase one of the Minis and review it as quickly as possible. The photo below displays the filament jam problem that happens when feeding either Colorfabb XT or t-glase filament in to the TAZ 4. Initially, I thought I had this solved by setting up another fan to great the extruder and stop so-called temperature creep from melting the filament. But actually this second fan just worked part of the time. In fairness to the Lulzbot organization, the TAZ 4 printer was really designed to printing PLA and ABS, both which it handles quite properly.The reason may lie in a common denominator between e-cigarettes and their combustible counterparts: nicotine. While the study hints that more research is required to determine if this association is only casual, it's important to note that while e-smokes don't contain tobacco, the battery-powered devices do deliver smoking in aerosol form. ‘Nicotine's addictive properties are a risk for any age group, but with adolescents, the stakes are even higher,’ says Dr. K. Vendrell Rankin, director of Texas A&M University Baylor University of Dentistry's Tobacco Treatment Solutions.
