How to Improve your 3D Prints

Understanding the Basics of 3D Printing

3D printing is an excellent way to bring your digital creations to life. But, it’s not as simple as just pressing the print button. Before diving into the world of 3D printing, it’s essential to understand the basics.

Choose the Right Filament

Choosing the right filament is crucial to the success of your 3D print. Filaments come in different materials, including ABS, PLA, Nylon, and PETG. PLA is the most commonly used material as it’s easy to use and produces high-quality prints.

Calibrate your Printer

Calibrating your printer is crucial to get accurate prints. Check your printer manual for calibration instructions or download a calibration guide from the internet. Calibration ensures that your printer’s nozzle is at the right height from the print bed and that the extruder is pushing out the right amount of filament.

Cleaning your Printer

Keeping your printer clean is essential to the quality of your prints. Clean the print bed with rubbing alcohol to remove any dirt or grease. Use a lint-free cloth to clean the nozzle and extruder.

Improving your 3D Prints

Now that you have a better understanding of the basics let’s explore some tips to improve your 3D prints.

Use a Raft

A raft is a layer of plastic that goes under your print. It helps to keep your print stuck to the bed and provides an even surface for your print. This is especially useful for prints with a small surface area.

Print at the Right Temperature

Different filaments need to be printed at different temperatures. Printing at the right temperature ensures that the filament melts correctly and doesn’t clog the nozzle. Check the filament manufacturer’s website for the recommended printing temperature.

Use Supports

Supports are essential for printing objects with overhangs or complex geometries. Supports are small pieces of plastic that the printer creates to support the overhanging part of the print. Supports can be easily removed after printing.


Cooling your print is essential to maintain its quality. Printing at too high a temperature can cause the print to warp or deform. A fan can be used to cool the print as it’s being printed, or you can print in a room with air conditioning.


Post-processing is the process of cleaning up your printed object to make it look more polished. This can be done in many ways, including sanding, painting, or adding a coat of clear varnish. Post-processing can take your print from a rough prototype to a finished product.

FAQs for how to make your 3d prints better.

What are some common issues with 3D prints?

Common issues with 3D prints include poor bed adhesion, stringing, warping, layer shifting, and poor surface finish. These can be caused by a variety of factors, such as incorrect temperature settings, insufficient cooling, incorrect nozzle distance from the bed, or incorrect bed leveling.

How can I improve bed adhesion?

To improve bed adhesion, make sure your 3D printer bed is clean and level. Use a bed adhesive such as glue stick or a specialized bed adhesive mat. Try increasing the bed temperature or using a brim or raft.

What causes stringing and how can I prevent it?

Stringing occurs when melted filament drips and creates unwanted strands between printed features. To prevent stringing, try reducing your printer’s nozzle temperature, increasing your printer’s print speed, or enabling retraction settings.

How does temperature affect 3D prints?

Temperature is a critical factor in 3D printing. Too low of a temperature can cause print failures or poor layer adhesion, while too high of a temperature can cause material degradation, stringing, or warping. It’s best to research the recommended temperature range for your particular filament.

What should I do if my prints are warping or lifting off the bed?

If your 3D prints are warping or lifting off the bed, try adjusting the printer bed temperature, increasing the bed adhesion, or adding a skirt or brim to your print. You can also try covering your printer with a temperature-controlled enclosure.

How can I improve my prints’ surface finish?

To improve your prints’ surface finish, try sanding or polishing them after printing. Using a high-quality filament can also improve surface finish. Adjusting your printer’s retraction settings and print speed can also help.

How important is print speed?

Print speed is an important factor in 3D printing. Too slow of a print speed can cause over-extrusion and sagging, while too fast of a print speed can cause under-extrusion, stringing, and poor layer adhesion. It’s important to find the optimal speed for your printer and filament.
