Simple Measures To Prevent 3D Printing Issues

Supporting Bondtech Customers

Bondtech is a small company based in Sweden with a growing legion of customers worldwide. We are known for our extruders and upgrade kits for desktop and professional 3D printers, enabled with our Dual Drive Technology.

We are also known for our comprehensive and multi-level customer support, much of it provided around the clock by Bondtech’s founder Martin Bondéus.

We serve a big and multi cultural community of filament 3D printer users, from all walks of life, from very diverse levels of academic or professional training, and with mixed knowledge and experience levels in 3D printing.

Because of our mixed audience there is a thin balance we want to achieve between supplying just enough information to allow a less experienced user to understand the matters, and simultaneous deep enough to be useful to more experienced members.

In this article we want to shine extra light on the more common issues our customers face, and on how important it is to act preemptively in order to avoid problems that may cause losses and/or frustrations easily avoidable.

We will focus the flow of information to the most relevant preventive measures, tweaks and fixes we hope will vastly improve the user experience with Bondtech products.

This is a living document that will be updated regularly according to what we see coming through the Customer Support requests.

What are the most common causes for 3D printing problems?

The following are the most common sources of problems and hardships reaching our Customer Service that are easily preventable. Right below you’ll find what we recommend to focus on to avoid these and others, in what we call preemptive solutions for 3D printing problems.

Wrong
Firmware Settings

Effects of using the wrong firmware may be over or under-extrusion; printer showing the incorrect temperature; and failing calibration tests.

Wrong
Print Settings

Effects of using the wrong print settings may be small part defects; over or under-extrusion;but may also be major issues like clogs and jams.

Issues With
Bed Adhesion

When you experience bed adhesion issues, the visible effects may be part warping and/or detachment; and inconsistently laid first layers.

Nozzle And Heat Brake
Not Tight

If the nozzle is not properly tight against the heat break, the effects may be material leaking; formation of blobs; and jams.

Preemptive Solutions for 3D Printing Problems

Why do we tweak the firmware?

Bondtech business is based on adding value to the printers our customers use by improving their reliability and performance. Our extruders add-on to the hardware of the 3D printers we upgrade. Because of that hardware upgrade, we always need to update the printer’s software as well.

Find below descriptions and links to Bondtech documents that will help you do the correctment adjustments to the firmware. This is an important step to avoid extrusion problems and prevent hardware damage.

Why to change the print profiles?

It’s not a mandatory requirement to change the print profiles used before upgrading a 3D printer with Bondtech extruders.

But, if the capacity of the system is improved, shouldn’t the settings be adjusted to the new possibilities?

Find below descriptions and links to profiles that were tweaked by our Product Development Department to take advantage of all the skills and features our extruders provide.

We’ll be adding profiles to this list. Come back later if you didn’t found what you were looking for.

It is important to know..

… that profiles are highly material dependent. Slight shifts in composition or in conditions like room temperature and moisture may require profile tweaks.

Different materials, manufacturers, ambient conditions, and hardware setup may impact in the performance of the profile it self.

Bare in mind a printing profile is many times a sum of personal choices. The profiles available here should be taken as a starting point to be adapted by everyone to his personal preferences, materials availability, ambient conditions, and hardware setup (nozzles, hotends, …).

Why is bed adhesion so important?

The print bed is not only the base where the 3D printer will lay down the part, it is more the anchor surface that holds the part in place until printing is finished.

Forces like inertia (from bed movement), drag (from tip of nozzle), or contraction (from material cooling down) will counteract that stability along the whole printing process, and if these forces rise above the holding force, they will cause the part detachment.

There are several origins for part detachment:

  • Bad bed levelling;
  • incorrect bed temperature;
  • not enough contact surface to bed;
  • incorrect settings to build first layer;
  • bad adhesion solution.

We will discuss each in more detail later in this article, but in what regards to bed adhesion solutions, it is important to know:

  • Different print surfaces will require different adhesion solutions (eg. Glass requires glue or hair spray to grab PLA);
  • Different materials will require different adhesion solutions (eg. Nylon does not adhere to PEI);
  • Use the right bed adhesion solution to improve your chances of finishing prints with success.

Even if the bed is properly levelled, you’ll still need a proper adhesion solution. Not all surfaces are adhesion-ready but all of them, ready or not, need to be clean.

Below you can see what the manufacturers recommend you to use with the print beds they supply.

Prusa 3D Printers

Prusa i3 MK2/MK3

The Prusa i3 MK2/MK3 3D printers use magnetic heatbeds with replaceable PEI spring steel print sheets. You can know more about them here.

PEI is a very good bed adhesion solution to print ABS, PLA and many other materials. To be effective it must be well cleaned and greaseless. Isopropyl alcohol is a very good solution to degrease the print bed.

Clean your metal sheet before each print to avoid the issues related with bad bed adhesion.

Be aware that some materials stick too much to the PEI steel sheet. With these materials it is recommended to use an additional adhesion agent that will act as separator to protect your PEI steel sheet.

Use an adequate glue stick or spray if you will use TPU or other flexible filaments, PETG, XT, or CPH.

Ultimaker 3D Printers

Ultimaker 2, 2+, 3

These Ultimaker 3D printers use a removable borosilicate glass surface over a heated print bed. Borosilicate glass is known for its very low thermal expansion coefficient, making it more resistant to thermal shock than any other common glass.

Glass has many pros and cons as a print surface but like most other surfaces, to be effective it must be well cleaned and greaseless. Isopropyl alcohol is a very good solution to degrease the print bed.

Clean your glass before each print to avoid the issues related with bad bed adhesion or uneven print surface.

PLA, ABS and other materials adhere relatively well to a heated glass, but to have better results it is recommended to use an additional adhesion agent and apply a thin layer of glue or blue tape.

The glue acts as separation agent, and reduces the risk of chipping the glass when removing the print.

Why is a tighten nozzle so important?

The nozzle is a bottleneck in the filament path.The heat brake lets 1.75 or 2.85mm thick solid material in, and the extruder lets 0.4mm thick molten material out.When the extruder is feeding material into the hotend, it has to exert pressure to push material through the nozzle.

Under pressure the molten material will travel through every escape route possible. If the nozzle is not properly tightened to the hotend, the gap becomes an alternative escape path, partially replacing the nozzle tip.

You can identify this issue when a brownish crud may be seen around the top of the nozzle and bottom of the heat block. Most common results are under extrusion and model contamination. More severe effects can be felt if the printer is left unattended and working for many consecutive hours.

It is important to know:

  • the nozzle should be tighten at higher than working temperature (eg. 285°C using E3D’s V6);
  • different hotends have different tolerances to torsion forces (E3D’s V6 will require you to firmly hold the heat block while (un)tightening the nozzle. On the Mosquito you just need to rotate the nozzle);
  • There is a recommended amount of torque required to (un)tighten the nozzle.

For these reasons, you should use a proper calibrated Torque Wrench. The Wrench should collapse when the maximum recommended torsion force is exerted, so the nozzle is tight and the hotend is not damaged.

Below you can see what the manufacturers recommend you to use with the hotends we are supplying.

Mosquito Hotends

Slice Engineering Torque Wrench

To proper install or change a nozzle in a Mosquito hotend, Slice Engineering recommends you use this 1.5Nm torque wrench.
