Sans-Serif Vs. Serif Fonts

As mentioned above, sans-serif fonts of any kind are much better to use than serifed fonts when 3D printing. But what is the difference between sans-serif and serif fonts? To answer this question, we’ll first need to know what “sans” and “serif” mean.

Firstly, a serif is an extended feature, line, or stroke that appears attached to the end of a larger line in any letter, number, or symbol. Now it may be hard to picture just by reading the definition, but you have undoubtedly read countless paragraphs written in display fonts that contain serifs.

The best font for 3D printing that you think of as elegant or fancy most likely includes serifs on its letters. Serif fonts are most often used in the body of physically printed media like books, newspapers, and magazine articles, as it is generally believed that serif fonts offer superior readability in this case, though science has yet to support this.

Serif fonts are also used in decorative text to make the words on a page appear more beautiful. Imagine a caligrapher drawing beautifully detailed letters on a page. The letters are more aesthetically pleasing to the reader with all of their thin lines and intricate details. There is most definitely a lot of artistic talent needed to do this; however, even if the letters look prettier, that doesn’t mean that the text will be easy to read on a 3D print.

The “sans” in sans-serif comes from the French word meaning “without.” So naturally, sans-serif simply means “without serif.” Knowing this, you’ve probably already guessed that, unlike serif fonts, sans-serif fonts do not feature any of those fancy serifs hanging off the ends.

Though sans-serif fonts do appear to be a bit less sophisticated and pretty than their serifed counterparts, sans-serif fonts have plenty of advantages of their own. Firstly, sans-serif fonts have less detail and contain thicker lines that make the letters appear bolder and more attention-grabbing.

This is why sans-serif fonts are so synonymous with breaking headlines at the top of newspapers. Sans-serif fonts grab your attention so that your eyes are naturally attracted to the most important information on the page.

Sans-serif fonts are also the default used when text is viewed on a screen. Whether using your computer, tablet, or smartphone, the small text you see when you’re writing emails, scrolling through Instagram, and reading online blogs is undoubtedly sans-serif.

Though not yet supported by science, It is the common view that sans-serif fonts are more readable on-screen than serifed ones. This is largely due to the extra details that come along with serifed fonts.

Small serifed letters that take up less than 20 pixels can cause distortions in the appearance of the letters, as the series will oftentimes be smaller than the size of a pixel. Overall, this can make a text much harder to read than if it were typed in a sans-serif font.

This same issue is why sans-serif fonts are superior when 3D printing as well. If you are printing in anything less than the largest of font sizes, your printer will have trouble drawing the intricate serifs attached to each letter.

The absence of these serifs means that your printer has much less opportunity to make a mistake and allows the text on your print to be much more legible than it would have been otherwise.

The Best Fonts For 3D Printing

So we’ve established that sans-serif fonts are much superior to serifed fonts when it comes to their use in 3D printing. But what are some of the best and most common sans-serif fonts to use?

In all reality, any sans-serif font you want to use will work perfectly, and there really aren’t any that will show up significantly better on your print than another. Still, there are some sans-serif bold fonts, both classic and contemporary, that see the most use in both 3D printing and other digital and physical media.

1. Helvetica


Helvetica is undoubtedly one of the most famous and widely used fonts out there. This Sans-serif font was invented by Swiss typeface designer Max Miedinger in 1957 and has since taken over the world.

Helvetica is commonly used on websites like Facebook and has been adopted for use in the logos of countless major companies and brands, including Microsoft, Jeep, Nestle, and The North Face, just to name a few. Helvetica is a familiar and well-respected font that anyone can recognize, so it's safe to say that Helvetica is an excellent choice for anyone who wants to include text in their next 3D print.

2. Arial


Arial is the best and most popular font in use today. Arial is most likely the default font on whatever word processor you use. Developed by Robin Nicholas and Patricia Saunders in 1982, this font has become the standard for most regular computer usage, not to mention its common use on the various billboards and signs you see around town.

The letters in Arial generally include straighter lines than those used in Helvetica, so letters printed in this font may be a bit easier for your printer to produce consistently and successfully.

3. Futura


Futura is another great font to use in your 3D prints. Despite the name, this font is actually quite old. Designed by Paul Renner in 1927, this font is based on geometric shapes. The circle is particularly important in this font as letters typed in the Futura font appear much more rounded than the letters of Arial and Helvetica do.

4. Proxima Nova

Proxima Nova is another great choice for inclusion in your print. Developed by American typeface designer Mark Simonson in 1994.

This is another common font used in the logos of many different companies like Buzzfeed and NBC. The most famous company to use this font is Spotify. Not only do they use it for their logo, but it is also used for all of the artists and track names on their app and website.

The Importance Of Font Size

Designing 3D prints that include text adds a whole new design element to the mix. The best font for 3D printing needs to be clear and readable so the reader doesn’t have to strain their eyes to read the text successfully.

It should also be big enough to see easily and maybe even printed in a color that contrasts with the rest of your print so that the text stands out.

Though this goes without saying, font size is incredibly important when it comes to the legibility of text on your print as well. Printing in a size that is too small will make it nearly impossible for anyone to read, and printing too large can take up space very quickly.

Ideally, you should always use a font size of anywhere from 18 to 26 points when designing text for your print. This will ensure that your text will be easily readable without being too large or too small.

More Tips To Ensure Your Text Is Readable

The font and font size you use are both incredibly important when it comes to the clarity and readability of text, but there are a few other things you can do to make sure that your text is as clear and easily readable as possible.

By default, you should always bold your text so that it sticks out more. Sans-serif fonts already include thicker lines than most other serif fonts do, but bolding the font will make it stick out even more and improve the clarity and readability of the text.

Another important thing to consider is whether you will be using raised or recessed text in your print. While recessed is generally viewed as being more readable, both can be easily readable if done correctly.

Using a different color for raised text or filling in recessed text with a different color can really help make the text pop out and appear clearer. Just make sure that any raised text you include is at least 0.5mm tall and any recessed text is at least 0.8mm deep.

The Technical Side of 3D Printing Text

When it comes to 3D printing text, there's more than meets the eye. So, let's dive deep into the nitty-gritty technical aspects of 3D printing text.

Printer Settings

Ever wonder how those layers and speeds affect your print? The key is in the printer settings. Adjusting the layer height, print speed, and temperature can significantly impact the quality of your text. With a little trial and error, you'll find the sweet spot!

Material Matters

Not all materials are created equal. PLA might give you sharp and clear text, while ABS could be a bit more forgiving with any printing imperfections. Consider what you want your final product to look like when choosing your material.

Support Structures

For intricate thin fonts or letters with overhangs, support structures are a lifesaver. They provide the needed backing to ensure your text comes out looking sharp and crisp.

Final Touches

After your print is done, don’t forget to clean up any strings or imperfections. A little sanding or using a heat gun can make your text look professional and seamless.
