11 3D PRINTING TIPS TO MAKE PERFECT PRINT QUALITY FOR BEGINNER

11 3D PRINTING TIPS TO MAKE PERFECT PRINT QUALITY FOR BEGINNER

Published May 7th, 2022 09:39

Have you ever seen a model in the store and asked yourself why they can make a perfect model like that? How to print it without failures? Even if you are a beginner or an expert in the 3D printing field, you may need to look at the list below and take note of the 3D printing tips we collected for you to have a nice work of printing.

1. Basic 3D printing tip: Level the Bed correctly 

One of the first 3D printing tips for beginners is to make sure your 3D printer's bed is flat and that the first layer is the proper distance from your nozzle; it's the foundation for all subsequent layers. “Leveling the bed” is when you have to prepare a smooth printing surface. That means no matter where on the bed you look, the bed is always the same distance from the 3D printer's nozzle. On a basic 3D printer, leveling the bed ensures that the nozzle is at the same height across the whole print surface. This enables the printer to put down a flawless initial layer and create the groundwork for a successful print. 

3d printing tips

Many 3D printers have sensors that automatically calibrate the bed so that the nozzle is always at the same distance from the bed. However, it is not an industry standard, and many kinds of 3D printers still require assistance to calibrate and level the bed. These printers commonly have a thumbscrew or knob on the underside of the bed that may be used to change the bed's tilt and distance from the nozzle.

To level the bed correctly is to help your printing avoid being failed, you may measure the distance between the nozzle and the bed using a sheet of paper or a feeler gauge at many spots across the bed. When the (clean) nozzle is at the right distance from the bed: the paper or gauge will have minimum resistance when pulled free, but will easily go back underneath the nozzle without effort. To assure accuracy, repeat this method two or three times.

2. 3D printing tips: Checking the temperature of the nozzle 

To check the temperature of the nozzle is one step you will never forget when comes to basic 3D printing tips. The temperature of the nozzle – or nozzles, if there are several nozzles – has a direct impact on the finished print's look. If the nozzle is excessively hot, it may leave filament threads between the pieces. When printing tall items, excessive temperatures or insufficient cooling might cause the previous layers to melt, causing the piece to deform. 

Include a one-centimeter cube on the opposite side of the build plate in your slicer when printing a tall item. This enables time for cooling by removing the hot nozzle from the print between layers. Use a wall or ooze shield structure if there are filament threads between structures, which is a typical feature in slicer applications. Controlling the temperature of the build plate, on the other hand, aids print adherence and prevents other problems. The layers of a model contract as they cool during printing, causing the print's bottom borders to peel away from the build plate. Warping might be an indicator that the bed temperature is too low, or that your bed adhesion needs to be checked.

Besides that, you need to keep your nozzles clean and change them if necessary. For a basic 3D printer when you purchase a new one, there comes along with 2 nozzles: one is attached on the hotend and a spare. You may need to buy more nozzles as well. When the nozzle wears down, the hole widens, causing your carefully planned print calibrations to be thrown off. Even worse, dirt and overcooked plastic might jam your hotend's inner workings. When you notice small gaps in your print or too much stringing, you know your nozzle is failing. If 100mm of filament forms wild curlicues instead of flowing straight down, your nozzle is unclean, and you should replace it. Keep the nozzle's exterior clean as well. A heated nozzle will gather stray filament wisps, which can subsequently drop on your print. Scrape the outside of the nozzle with a wooden craft stick or a brass brush while it's still hot.

3. 3D printing tips: Keep the filament fresh and organized 

If you pay close attention to tips for printing, you will find out that your filament is one of the most important things. Many filaments are hygroscopic, which means they adore water and absorb it from the atmosphere. Exposed filament, particularly ABS, nylon, and flexible materials, absorbs moisture and causes issues. PLA is the most often used 3D printing filament since it is the easiest to work with and available in a wide range of colors. You don't have to worry about keeping it packed in airtight containers because it doesn't absorb moisture easily. But that doesn't mean you can toss it around when you don’t use it. Dust and tangles are the most common issues with filament. This is why you have to add one thing to your tips for printing is appropriate spool management is critical to printing success.

What usually happens when your filament is not treated right is as the water in the filament turns to steam and bubbles out of the plastic during extrusion, it expands. The filament passes through the nozzle, it snaps or crackles, and close inspection reveals what appears to be smoke. The major issue, though, is that when the print is done, it will appear rough. Therefore, if you want to ensure your printing process works smoothly, then you need to organize the filament neatly and create easy access to it while running your 3D printer. Using a cleaning sponge will prevent dust and grit from blocking your printer. Attach a little piece of sponge to the filament using a binder clip before it enters the extruder. Even unpleasant are tangled in your spool. If the filament on your spool knots, it will cease feeding through the printer, resulting in a failure. Allowing the spool to uncoil will cause tangles. This entails always having one hand on the spooled filament and maintaining it properly coiled by taping it in place.

4. 3D printing tips: Make sure the print bed is clean

One of the 3D printer tips you may want to do often is clean the print bed. Even if your print surface is absolutely flat and level, if it isn't clean, plastic won't attach to it. It's an unfortunate fact of life, but remnants of skin oil from your hands might interfere with the adherence of the initial layer. A lot of PLA is also manufactured with sticky additives for added gloss and glitter. These hidden substances might leave a greasy residue on your printing surface.

After each print, wipe the print surface with 91% isopropyl alcohol and a paper towel to keep it squeaky clean. It's fine to use a little glue stick if you're still having difficulties getting the initial coat to attach. Smear an even layer of washable glue stick on your heated print surface - the purple sort is excellent. The adhesive layer adds a little more grip to keep your prints in place.

5. Basic 3D printer tip: Adjustment and Maintenance

Unless you want your printer broken too soon or your printing result always appears in the garbage, you should save the tips printing in your mind: remember always to keep up with the maintenance of your printer. Each 3D printer has its own unique qualities, as well as certain issues that need to be addressed in order to increase print quality. 

Check for any kind of wobbling anywhere in the frame if you're seeing some unexpected quality concerns. Make sure the bolts are securely fastened and that all 90-degree angles are square. If everything appears to be in working order on the hardware side, don't forget to check the manufacturer's website for new firmware.

Changing nozzles is a routine aspect of maintenance that may improve your printing quality simply by replacing a worn-out nozzle as well. Alternatively, you could wish to increase the material or orifice diameter of your nozzles to be able to print with other filaments at a quicker rate. Knowing how to remove and replace a 3D printer's nozzle is an essential item to have in your 3D printing toolkit.

6. 3D printing tips: Choose the right material for your project 

The more 3D printing you do, the easier it will be to choose the proper 3D printing filament for the job. Because there isn't a one-size-fits-all filament that will work for everything, you'll have to experiment to see what works best. Based on what you want to print, you can not use the same material for all of it because the material may not adapt to the design. That will make your result look terrible. And for a prototype and a final product, you might not want to employ the same materials or finish. Is a rubber-like substance, something slightly flexible, or a hard, stress-resistant material required? You should search for the material you need carefully, read the detail of it then consider whether it’s suitable for your printer and design or not. That makes things work nicely.

7. 3D printing tips: Pay attention to the design guideline carefully 

Before you can complete the design of your future 3D printing, you must first pick the material that will be used to construct the customized design. All of the materials are unique, with unique qualities and limits, yet they all follow distinct design guidelines (direction)! If you want to receive the greatest outcomes from a basic 3D printer or even the advanced one, double-checking these design criteria should become a new habit. 

All of these guidelines will ensure that the results are of high quality. What happens if you don’t follow the guidelines closely? You won't receive all of the advantages of 3D printing, and your part may break during or after the printing process. Your print quality will be assured if you follow the design standards.

8. 3D printing tips: Make sure all parts are solid before printing

One of the tips for 3D printing before you move your project to a 3D printer is that you should double-check your part's soundness. It's true that making a solid 3D model isn't the only thing you'll have to accomplish. You also want your model to be 3D printable on the machines so that you may skip iterations with customer support and save time in the process. This is why you must consider their constraints, such as the minimum width required for your products. To minimize any hazards, make sure that none of your design's little pieces are less than 2mm in diameter, since they might easily shatter while being prepared for you. To avoid any of these issues, follow the design standards once more.

9. 3D printing tricks: Slow down the printing speed

3D printing tricks that you can use when you are in processing your project is lowering the printing speed. The visual quality of your finished output is reduced by echoes or ringing around the edges of features on the final object. Vibrations from the extruder's operation generally produce these distracting lines. Reduce the printing speed to solve the problem. Make sure the extruder has enough room to move around so the printed area doesn't overheat or cause other issues.

10. 3D printing tips: Get acquainted with your slicer

A slicer is software that turns a 3D model into G-code instructions for the printer. The slicer regulates the printer's temperature and movement, as well as whether or not supports or rafts are created, and many other aspects of the printing process. Learning how to use all of the different options can help you enhance your quality, regardless of the slicer you use. 

There are several slicers available, many of which are free, but if you want a certain function, you may need to investigate premium choices as well. If a few prints turn out rough, don't switch to a different slicer: The settings, not the slicer, are most likely to blame for any problems you're having. Investigate the issue, then alter one setting at a time. Try printing it again to see if it helps.

11. 3D printing tips: Post-process

After the thing has been produced, spend some time inspecting it for any flaws. That’s on tips for 3D printing you will never forget. A sharp hobby knife or sandpaper can be used to remove supports or remove tiny defects, especially if painting or polishing is required. Certain polymers, such as ABS, respond well to acetone vapor treatment. The model will have a shiny surface, but be mindful that the procedure may weaken it as the plastic degrades.

These 3D printing tips are good for you to start something enjoyable. Just have the idea in mind, prepare all the stuff you need, and pay more attention when you work. Don’t be afraid of re-printing and don’t give up your project too soon. Hope you have fun with it!
