10 Key Things to Do Before Each 3D Print

When it comes to 3D printing, it's not all about the settings. The key is to be well-prepared. The majority of failed prints result from careless errors made before printing. Your prints will be more professional and accurate if you stick to a basic checklist and utilize the correct equipment before each 3D print.

1. Clean the Print Bed Properly

The first step to a successful print is a clean print bed. Glue or dust, no matter how small, can prevent filament from adhering. Among the most typical types of covert issues are fingerprints.

Before each print, make sure to wipe the bed. For this, isopropyl alcohol (IPA 90% or greater) is the ideal tool to use. It is effective in removing grease and does not leave behind any unnecessary residue. Another crucial item is a microfiber cloth, which will not damage the surface in any way. When alcohol isn't cutting it, try a combination of dish soap and warm water for a more thorough cleaning. For their glass mattresses, many users also keep an ammonia-free glass cleaner on hand.

Having a clean bed immediately enhances adherence. Reducing print failures can be as simple as this.

2. Level the Bed Carefully

With bed leveling, you can be certain that the nozzle will always be at the same distance from the bed. Uneven surfaces on the bed will prevent the filament from adhering evenly.

A paper level or feeler gauge is an easy tool for this task. To further simplify matters, many printers use auto bed leveling sensors. Thumb screws or leveling knobs are necessary for manual leveling as they allow you to modify the height of the bed. Bed leveling visual test prints are another tool that customers utilize to get the precision just right.

Building a solid foundation begins with leveling. Even the most ideal conditions will not work in its absence.

3. Set the Correct Z-Offset (Nozzle Height)

Z-offset determines the nozzle's proximity to the bed. When it comes to 3D printing, this is a crucial parameter. Regardless of how well your print job turns out, it will fail if this is incorrect.

Automated, precise Z-offset setting is possible with the aid of a digital probe or BLTouch/CR Touch sensor. Many artisans still rely on plain old printer paper as an auxiliary tool. You can find Z-offset adjustment tools in the control menu of some printers. When it comes to fine-tuning, a first-layer calibration print is really useful.

With the right Z-offset, the filament will "squish" onto the bed just a little. The print strength and adherence are both enhanced by this.

4. Preheat the Printer Before Printing

By preheating, you may stabilize the temperature of the bed and the nozzle simultaneously. The first layer might not adhere well if you neglect this step.

This process relies heavily on the heated bed system, which is standard in most printers. The firmware includes a temperature controller that guarantees consistent heating. Infrared thermometers are another option for measuring actual surface temperatures. When printing in large quantities or with complex designs, some novice users prefer to use enclosure heaters

The optimal bed temperature for PLA is between 50 and 60 degrees Celsius. Stable heat is useful for avoiding lifting and warping.

5. Use Good Filament and Dry It if Needed

Even with the best settings, a faulty filament can cause a mess. Bubbles, thin layers, and poor adhesion are all results of filaments that are damp.

To keep filament dry, a filament drier box is a great tool to have on hand. Another option for keeping moisture at bay is to use storage containers made of silica gel. To keep spools of unused filament safe, use a holder with a lid. Even though a dryer is safer, some people still opt to dry their items in the oven, which is a low-heat approach.

The filament is easier to work with and stays put on the bed when it is dry and of good quality.

6. Apply Bed Adhesion Tools When Needed

Extra support is sometimes necessary for prints to adhere, particularly on tall or big models.

Among the many adhesives available, a glue stick ranks high. It improves grip by creating a thin, sticky layer. Because of its inherent ability to hold filament well, a PEI sheet—whether smooth or textured—is among the greatest modern bed surfaces. When it comes to strong bonds, some users also turn to 3D printer adhesive sprays. A blue painter's tape, which is effective with PLA, is another useful tool.

These instruments aid in stabilizing the first layer and reducing warping.

7. Double Check Slicer Settings Before Printing

Layer by layer, your slicer directs the print process. Even if your hardware is flawless, failure can still occur due to incorrect settings.

The primary instrument here is a slicing program such as SelfCAD’s online slicer. You may see the print's initial layout with the first-layer preview function. Due to the improved sticking properties of slower first layers, a print speed control option is crucial. To check for weak or floating areas, you can also use the support preview tools. Never print a model without first reviewing it. Time and filament are both saved by this process.

8. Inspect the Model and First Layer Carefully

It is essential to verify the model's settings before beginning a full print. Major setbacks can result from minor mistakes.

In order to examine models, your slicer comes with a 3D viewer. If you need to do rapid inspections, a test calibration cube or first-layer test file can be helpful. The test pattern for bed leveling might show where there are uneven places. Camera monitoring systems also allow certain users to observe prints in real-time.

The initial layer ought to appear flat and marginally compressed. Put it down early and fix it if it seems bad.

Best 3D Design Software for Education

Having discussed Key Things to Do Before Each 3D Print, it becomes important to reveal the best 3d printing software. SelfCAD is one of the best 3D modeling software. It's easy to use and it comes with various tools like freehand drawing and sketching, image to 3D model, powerful 3D sculpting brushes, easy to use selection modes and various deformation and modification tools. The video below shows the overview of the software.

Conclusion

A lot of planning goes into 3D printing. In most cases, inattention to detail before printing is to blame, rather than the printer itself.

Your chances of success will increase significantly if you take the time to clean the bed, level it, set the precise Z-offset, and use high-quality tools. You will be able to save filament, time, and frustration by adopting these basic behaviors and using these products.

Just a little bit of planning ahead of time can transform an imperfect print into an ideal one. 

Frequently Asked Questions (FAQs)

1. What to do before a 3D print?

Make sure the bed is free of dust and oil before starting a 3D print. Before setting the nozzle height, make sure the bed is level. Before loading, ensure that the filament is dry. Check the slicer's temperature, speed, and support settings. Before printing, make sure to preview the model.

2. Is 3D printing 40k illegal?

The model license determines it. It may be against the law to print and sell or share copyrighted Warhammer 40K models without the proper authorization. It is under the law to print out free or original designs. Before using or selling a model, make sure you check the license.

3. What is the 45-degree rule in 3D printing?

According to the 45-degree rule, supports are typically unnecessary for overhangs up to 45 degrees during printing. Props are usually required at steeper angles. Print quality and paper consumption are both enhanced by this.

4. What should I do after every 3D print?

Before removing the print, allow the bed to cool. If necessary, make the bed. Verify if any filament remains in the nozzle. To maintain filament quality, store it in a dry location.

5. How long does 1 kg of filament last?

The print size determines it. Even tiny prints have a sturdy lifespan. Filament wastes more quickly in large prints. One kilogram can typically print around ten to twenty medium-sized models.

6. Can I legally sell 3D prints?

Sure, but that's assuming you own the rights to sell it. You can sell some models and not others. It is always within the law to sell your own creations. Prioritize checking the file licensing.
