Better 3D Printer Filament Cooling Duct Improves Print Quality

While printing filament cooling ducts for our E3D Titan Aero toolheads, I noticed that some ducts had consistently poorer print quality on the overhangs of some corners, while others had even performance on all corner overhangs, even when printing with the same printer and filament roll.  Keith pointed out that I had switched toolheads between stock and one of our upgraded E3D Titan Aero toolheads with the surround filament cooling ducts.  I hadn’t expected the more even cooling to make that much of a difference, but it indeed does.

LulzBot TAZ 4 and TAZ 5 Power Suppy

We’ve recently had demand for upgraded LulzBot TAZ replacement power supplies for customers that had the early plastic cased supplies that shipped with the LulzBot TAZ 4s and early  TAZ 5s.  The later metal cased TAZ 5 supplies are great, but replacements are in short supply.  Customers also prefer a power switch on the power supply allowing the power supply to be shut off when not is use.  This conserves power and eliminates from noise the power supply cooling fan while extend the fan’s life.

Building on the idea LulzBot used with earlier TAZs, we designed a new endcap to fit the Mean Well SE-450-24 450W 24V power supply and have assembled upgraded TAZ 4 and TAZ 5 power supplies!

Upgrading an earlier LulzBot TAZ to TAZ 6 specifications

We’re working on turning a number of prototype TAZ 6 chassis into upgrade kits for prior TAZ versions, and asked the community what they might want. In the process, we’ve received a number of questions about the options for upgrading a LulzBot TAZ 4 or 5 to TAZ 6 specs, and have added those as well. Check out the discussion on Options for upgrading to a LulzBot TAZ 6
