3D Printing Basics: How to Print Spheres

Posted on July 25, 2021 by Mel Hawthorne Leave a Comment

One of the most difficult shapes to create with a 3D printer is a sphere. Spheres are difficult for several reasons. Firstly, spheres have a tiny contact point with the print bed, making them hard to adhere in place. Secondly, spheres have a lot of overhangs that need support. Thirdly, FDM printers end up leaving visible layer lines when printing curves that cross the Z-axis. It is possible to address these issues; however, each fix comes with its own compromise too.

Add Support Structures and a Brim or Raft

By adding a combination of support structures and a brim or raft, you can address two issues in one. The brim or raft helps to secure your print while the support structures keep the overhangs from drooping.

A raft is a thin sheet of print material printed first, underneath the print, upon which the print sits. A brim is almost identical, but it only touches the print at the edges and doesn’t go underneath.

Rafts and brims work by increasing the contact area with the print bed, which increases the adhesion force holding the print in place. A raft is typically more difficult to remove due to the increased contact area. Both options are intended to be cut away during post-processing.

Support structures work well with rafts and brims as they can connect to them easily. They are designed to provide support to extreme overhangs to prevent drooping. Typically overhangs greater than 45 degrees from the vertical need support, although this can vary from printer to printer. Again, these need to be removed during post-processing.

Support structures, rafts, and brims all leave some artifacts on the sphere’s surface where they contact. Even if they’re removed carefully, the artifacts will need to be smoothed.

Cut It in Half

This may sound a little extreme, but you can then print the two halves face down if you cut your sphere perfectly in half. This eliminates the need for a raft, brim, or support structures. Unfortunately, it does mean that you need to glue the two pieces back together once they’re printed.

We highly recommend that you triple-check that your sphere is perfectly cut in half before printing, as otherwise, you’ll be more likely to end up with uneven weight distribution. The type of glues you can use vary by filament type, but superglue generally offers the best finish as so little needs to be used for a solid connection.

You will generally need to smooth any unevenness that you see at the joint of the sphere. If your print bed was slightly too hot, you might see a slight elephant’s foot effect, resulting in an equatorial ridge. It’s a good idea to print the two halves separately. Otherwise, you can end up with retraction-related issues such as stringing and blobbing between the two halves.

Use a Low Layer Height

Any curve that crosses the Z-axis will end up with a stair-stepping appearance. This is an inherent part of FDM printing but can be minimized by printing with the lowest layer heights possible. Doing so reduces the height of each step, making them less distinct and needing less smoothing in post-processing. Unfortunately, reducing the layer height also increases the print time as the print head has to make more passes to reach the final print height.

Here you can see the effect that the labeled layer heights have on the stair-stepped appearance. Image courtesy of http://3dprototypesandmodels.

15 year old develops the most reliable and fastest 3D printer

07/10/2014

The number one problem that 3D printer owners face today is print speed. People want to get what they want at the touch of a button. In recent years, we have become accustomed to the fact that all our desires come true immediately. For example, if you want to print a document from a computer or tablet, then you will have to wait at most 5-10 seconds. When you want to open a website on your smartphone, it's a matter of 1-2 seconds. If we compare modern technologies with those that we used several decades ago, it immediately becomes clear that we live in a new reality that simply cannot stand still. And 3D printing technology - in terms of speed - is still in the Stone Age.

This is to be expected. Still, 3D printing is a relatively new technology, especially when it comes to consumer home 3D printers. Sometimes it can take a whole day to print an object the size of a basketball. Printing an item the size of a Rubik's Cube will take several hours. Over the past few years, the speed has increased slightly, but there are still no noticeable improvements. If anyone can turn the tide, it's Thomas Suarez and his company CarrotCorp.

15-year-old Thomas Suarez first came into the spotlight a few years ago when he created the game Bustin Jieber. Since then, he has already spoken at a TED conference, appeared on the BBC, and also got the opportunity to meet many important and famous people.

Suarez is now into 3D printing. He got to know Bre Pettis in 2012 and even went to MakerBot's Botfarm.

“I told my dad about 3D printing and he said, 'Oh, that's impossible!' Suarez recalls. “He didn’t believe this could happen.”

Soon after, Suarez decided to prove to his father that 3D printing was more than real, and went to the MakerBot workshop. Needless to say, he managed to convince his father, and Thomas himself became even more interested in this unique technology. I was so interested that I decided to accelerate its development.

“Recently I received a patent for 3D printing,” Suarez says in an interview with the BBC.
