What is under extrusion in 3D printing?
Under extrusion in 3D printing is a bummer! It’s when the printer can’t supply enough filament through the nozzle during printing. This leads to gaps or weak spots in the printed object’s structure. Causes include a clogged nozzle, low print speed, incorrect temp, insufficient tension in the filament feeder, and a partially blocked filament.
To fix under extrusion issues, check for nozzle blockages or clogs. Cleaning the extruder and replacing faulty parts might help. Adjusting print speed, increasing/decreasing temp, checking filament spool placement, and making sure tension is correct can improve print quality.
Also, avoid buying poor-quality filaments from untrustworthy sources. Substandard products can cause various problems with poor print finishing.
Causes of under extrusion in 3D printing
To identify and troubleshoot under extrusion issue in 3D printing, you need to understand the root causes. In the section, “Causes of under extrusion in 3D printing,” we’ll discuss the possible reasons for under extrusion and how to deal with them. This section is divided into four sub-sections: Insufficient filament flow, Clogged or partially blocked nozzle, Incorrect print speed settings, and Issues with filament quality.
Insufficient filament flow
Under extrusion in 3D printing is oftentimes caused by insufficient filament deposition. This is when the printer’s nozzle fails to put enough material on the print bed to form an object. To solve this, here are 6 steps:
- Make sure the filament is correctly loaded and being fed through the printer.
- Clean the nozzle from any residue or clogs that could be blocking the flow.
- Adjust temperature settings for the correct melting and viscosity rate.
- Verify the filament diameter is suitable for your nozzle – differences can affect flow rates.
- Slow down printing speed – this will allow accurate deposition and prevent under-extrusion.
- Replace the nozzle if all else fails – blockages can cause damage over time.
Under-extrusion can also cause layer adhesion issues and surface deformities. So it’s important to address it quickly. Here are some tips to prevent this:
- Have regular hygiene checkups for your printer.
- Choose quality filaments for your machine.
- Follow manufacturer’s instructions.
By doing this, you can get the best out of your 3D printing models. Don’t let a clogged nozzle stop you from achieving your 3D printing goals – take the steps to success!
Clogged or partially blocked nozzle
Clogged or partially blocked nozzles can impede efficient 3D printing. Causes can be dust, debris, low-quality filament, or lack of maintenance. Flow gets disrupted and the printing process is disrupted.
It’s important to keep the nozzle and extruder gear teeth clean. Use high-quality filaments to reduce blockages. Acetone or specialized cleaning solutions can help with clogs.
Regular maintenance and periodic checks of the printer’s core components are key for optimal performance. Not cleaning and inspecting can lead to under-extrusion and other defects.
Pro Tip: Don’t leave melted filament in the nozzle for long periods. Purge any remaining material after use to minimize accumulation, which can cause obstructed nozzles. Beware of incorrect speed settings too!
Incorrect print speed settings
Print speed inconsistencies can be one of the many causes of uneven material distribution in 3D printing. This can lead to no layer formation, lack of topology, and weak structure in the model.
To avoid this problem, follow these 5 simple steps:
- Set a moderate print speed.
- Make sure your printer’s firmware is up to date.
- Adjust temperature settings according to required material specifications.
- Avoid tampering with filament feeding rate.
- Regularly clean and maintain print bed as per guidelines.
It is important to remember that print speed needs may vary for different printer types, models, and materials.
If neglected, this issue can cause failed prints and more material wastage. If you experience under extrusion while printing, you need to examine all probable variables before identifying the cause.
They say that almost half the time spent on a 3D Printing project is devoted to diagnosing the malfunction that happened at some point. Incorrect print speed settings usually seem harmless – just another adjustment to make – but can be the source of subtle imperfections that can cause bigger technical problems if overlooked repeatedly.
Looks like my 3D printer’s got an attitude – it only wants top-notch filament now.
Issues with filament quality
When it comes to 3D printing, filament-related issues can cause under extrusion, resulting in poor print quality and wasting of time and resources.
These issues include:
- Dust, debris, or moisture in the filament.
- Inaccurate diameter or fluctuating thickness.
- Air bubbles in the roll.
- Poor storage, leading to breakages and twists.
- Clogging due to burnt plastic, debris, or wrong temp.
- Using low-quality filaments.
It’s important to handle and store filament properly to avoid defects. Quality should never be compromised as cheap filament will lead to bad outcomes and wasted money.
In 3D printing, filament is a key factor. This involves testing, product development using AI and ML algorithms. Some printers need bed calibration, but those with quality filaments don’t.
Cheaper materials come with their own drawbacks. So why settle for a half-printed object when you can fix under extrusion and get the full picture?
How to fix under extrusion in 3D printing
To fix under extrusion in 3D printing, you must implement solutions that will refine the printing process. With the right techniques, you can avoid clogs in the nozzle, calibrate the extruder steps/mm, adjust print speed settings, check and replace the filament, and increase the print temperature. These sub-sections are key to resolving under extrusion issues in your 3D printing endeavors.
Increase the print temperature
To perfect 3D printing, the temperature must be adjusted. Here’s how to raise the heat for better outcomes:
- Find the ideal temperature range for your filament.
- Increase the hotend temperature in 5°C increments and try it on a small print object until you get the results you want.
- Check the nozzle diameter. Bigger nozzles may need higher temps.
- Change the fan speed as high air flow can quickly decrease the printing temp.
- Think about using a different nozzle material that needs higher temps.
- Upgrade with a high-temperature hotend if necessary.
Be aware that sudden increases in temperature can result in over-extrusion or failed prints, so make changes gradually and carefully.
Raising print temperature can lead to issues like clogging from burned plastic scraps or warping from overheating. To reduce these issues, clean and maintain your printer regularly.
Also, investing in advanced software and tech upgrades can further maximize your printer’s performance and output quality.
For optimal 3D printing, adjust the print speed settings to a balanced speed.
Adjust print speed settings
To fix under extrusion in 3D printing, you need to get the velocity settings right. Here’s how:
- Lower Print Speed – This will let the printer move more accurately, without being rushed.
- Increase Travel Speed – This means the nozzle can move quickly without leaving much filament behind.
- Calibrate Jerk and Acceleration – This makes the printer’s movement smoother.
- Reduce Retraction – This reduces the amount of plastic oozing out when not printing.
Check what print speed works best for your filament with a temperature tower. And make sure your printer hardware is solid enough to support high-speed printing. Otherwise, adjusting the speed won’t help.
It’s time to unclog the nozzle, like a toddler blocking a sink!
Unclog the nozzle
For consistent 3D printing output, the nozzle must be clear of blockages. This can be done by removing any traces of filament and cleaning the nozzle. Here are 3 steps to unclog the nozzle:
- Take apart the hot end assembly.
- Heat the nozzle to its melting point.
- Use a needle or other suitable tool to remove blockages.

Calibrate the extruder steps/mm
To get successful prints, make sure your 3D printer’s extruder is correctly calibrated. You can adjust the extruder steps/mm to regulate and perfect the amount of filament being printed. It can solve under extrusion problems and boost print quality.
Follow these 6 steps for calibrating:
- Measure a 120mm length of filament.
- Mark it at 100mm.
- Heat the printer to printing temp.
- Print exactly 100mm of filament.
- Measure the filament from the mark.
- If too little is printed, raise the steps/mm by 5%.
You might have to repeat this process a few times to get the right result. Make sure there are no other problems like clogged nozzles or tangled filament before starting.
Keep a log of every calibration attempt and note changes and improvements. This way you can refer back if any issues arise.
Someone had under-extrusion problems for months. After reading online, they figured out their printer settings were wrong. After following our 6-step guide, their prints improved greatly with fewer failures. Be proactive and avoid dealing with a mess of failed printouts.
Best practices to prevent under extrusion in 3D printing
To prevent under extrusion in 3D printing with the best practices, keep the printer and filament dry, store filament properly, clean the printer regularly, use high-quality filament, and regularly maintain and calibrate the printer. These sub-sections provide solutions to ensure you achieve high-quality prints by avoiding common issues that arise due to poor upkeep of equipment or improper handling of the filament.
Keep the printer and filament dry
To avoid under extrusion in 3D printing, it is important to maintain the humidity level of both your printer and filament. Too much moisture can cause blockages, lead to bad print quality, clogs, skipped layers, and even filament breakage and jams.
