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.

Maintenance items on the Mini and Taz

To keep your LulzBot Mini and Taz performing at their best, it’s important to check for wear and loose parts periodically.
A few items you can check quickly and easily:

Loose bed mount screws
If you can spin any of the washers that hold down the corners of the bed on the TAZ 6 and Mini, they are too loose. Snug them up with a 2mm hex wrench
No “hulk hands” here though, be careful not to strip out the hole.

Play in the bed plate
Try to wiggle the bed in all directions checking for excessive play that may be caused by loose screws or worn bearings.

If you find more play than you’d expect, it may just be loose screws that secure the bed plate to the double bearing holders. Using a 2mm hex wrench, remove the screws that secure the heat bed washers. Being careful not to lose the screws washers, or spacers below the washers, remove the screws and washers, lift up the heat bed and set it off to the side, and check that the screws underneath the heat bed that secure the bed plate are all snug.

Check play again. If you’ve taken out the play, great! If not, it’s probably time to replace the bearings under the bed plate in the double bearing holders

Play in the X carriage
Wiggle the tool head in all directions to check for excessive play that may be caused by loose screws or worn bearings.

Culprits for play include looseness in the screw/s that secure the toolhead to the X carriage

Loose screws that secure the extruder and hotend to the toolhead mount, cracks in the extruder body and toolhead mount, and worn bearings in the X carriage and x carriage upper bearing holder.

Squeaky smooth rods
Wipe down the smooth rods with a lint free cloth to remove dust and residue. This will often remedy squeaks when the carriages are moving.

If you need to replace worn bearings, the old bearings need to be pressed out, and new bearings pressed in, which can be a bit of a challenge without the right tools.
We have factory made parts for the 1.03 “Foxglove” Mini that include the bearings and heat inserts already installed, so you can conveniently replace the entire bearings housing assembly instead!
All our Mini parts are conveniently organized with pictures here: https://itworks3d.com/product-category/parts/mini-parts/
Here are the parts that contain the bearings that you may want to replace:

E3D Titan Aero Toolhead for LulzBot® Mini Now Available!

Print solid AND flexible filaments on your LulzBot® Mini 3D printer, without changing toolheads!
Available in your choice of either 3mm or 1.75mm filament.

Check out the E3D Titan Aero at work

IT-Works 3D’s new toolhead based on the E3D Titan Aero extruder is compatible with all LulzBot® Minis and joins our successful and well regarded E3D Titan Aero tool head for TAZ 5 and 6 offering you convenience, performance, and greater filament options.

Prevent burned fingers!

A custom molded silicone boot surrounds the heater block, preventing accidental burns, and keeps stray filament from melting to the heater block, making cleanup of stray filament easy.

Abrasive filaments? Sure!

We can customize our E3D Titan Aero toolheads for you to better withstand the wear from abrasive filled PLA filaments like stainless steel PLA, carbon fiber PLA, and iron PLA.

Hob:
E3D Hardened Steel HOB GEAR
Heat Break:
E3D Titanium Heat Break tube (currently only available in 1.75mm)
Micro Swiss Wear resistant Coated Stainless heat break for E3D V6
Nozzle: 
Micro Swiss Wear resistant Coated Brass Nozzle for E3D V6 is a great balance of performance, price, and upgraded abrasion resistance
Micro Swiss Hardened A2 Steel Nozzle E3D V6 for maximum durability
E3D V6 Extra Hardened Steel Nozzle for maximum durability
Nozzle sizes vary by option, be sure to check them all for the size you’re looking for! Brass and copper nozzles tend to perform better than steel due to their better conductivity.

How do toolhead upgrades work?

– Purchase the optional parts you want
– In order notes, request that the upgraded parts be installed.
– We install the upgraded parts (we keep the stock parts) and ship you the toolhead tested and ready to print!
Upgrades usually take 1-2 working days

IT-Works 3D began building all E3D toolheads with upgraded BOCA sealed bearings starting Oct 2017 to improve bearing durability

Step up to the versatility and flexibility of an IT-Works E3D Titan Aero toolhead for your LulzBot®!
