Guide to Obtaining Great Prints

Avoid AirPrints, Don't increase temperature above settings

Does it affect your print? If not, don't worry about it. Otherwise see below.

On cold days the heatbed glass can lag about 10min behind the heatbed temperature. Close the window curtain to reduce ambient heat loss. Preheating the bed for a longer time before starting the print may help. If the heatbed continously does not reach target temperature, use the materials in MaSha to build an enclosure for the TAZ.

There is an edge inside the extruder in the filament shaft between the metal and plastic part. It can't be fixed, but the filament can be inserted in a way that the natural curl of the filament keeps the filament from getting stuck on that edge.

Use the PTFE tube to guide the filament into the extruder from the backside (display is front-side) of the printer.

We observerd Stainless-Steel PLA to be wobbly on some places on the spool. The wobbles will make the filament get stuck in the PTFE tube. Try without the tube. Watch the print and make sure filament does not get stuck.

• Check your model in the layer view of Cura.
• Wall thickness should be a multiple of the nozzle size.
• Try a finer profile.

This happened once, because the current regulation on the controller board was shot. Read the blog. Order new board and replace it.

You wall thickness should be a multiple of the nozzle size.

If you are printing thing walls for cookie cutters, make sure your wall is thick enough to be printed. You can check in cura in the layers-view.

Nylon Printing and Cleaning

Correct profiles for each material can be found in: ~/lulzbot/cura profiles/

Use Cleaning Filament when changing to a filament with a different extrusion temperature.

currently in realraum

• HIPS 3mm white
• Bridge Nylon 3mm aka "bridge"
• t-glase clear 3mm
• t-glase red 3mm
• PLA deep blue 3mm
• Stainless Steel PLA (proto-pasta)
• Cleaning Filament
• translucent PLA
• yellow translucent PLA
• nGen Black von colorFabb

See the Lulzbot Filament Guide on print-settings for various materials.

Nylon does not stick to the print-bed. Not even with the heat turned on.

1. Use Glue-Stick on printbed beforehand. Glue-Stick is in black LulzBot Bag, Please store there again after use.
2. Do NOT heat the printbed. That just leads to the Glue drying out early and the print failing.
3. Glue-Stick-glue is water-solvable. Clean printbed with wet wettex and paper afterwards!.

Other Opinions

Nylon should regularly dried at 80°C for 7 Hours and stored in airtight container with desiccant. (Under the Table)

Stainless Steel PLA sticks REALLY well to the PET surface. Don't use glue.

When the print is finished, wait for the pad cools and then VERY carefully try not to damage the print surface!

Everything with a filament diameter of 3mm (no less and no more) and extrusion temperature below 238°C that does not clog 0.35mm nozzles, like wood-,stainless-steel-,conducitve,“magnetic”-filament does.

To print 1.75mm filament, a different PTFE-Tube would be needed. However, Lulzbot no longer manufactures or sells them. Conceivably they are easy to make yourself from aluminum or PTFE with a lathe. Seeing as their newest Hexagon Hotend does not even mention the option of printing anything but 3mm filament, Lulzbot seems to have completely abandoned support for anything other than 3mm filament.

Quote from Lulzbot-Sales 2015-09-25:

I do apologize, but we no longer carry those tubes. We have tested several filaments on our printers, and prefer the 3 mm size, as it much easier to work with.
