It’s a shame that spheres are so difficult to 3D print, considering how common they are. It would be a great idea to 3D print some balls for backyard games or a stylish spherical lampshade. What is it about spheres that make them problematic for 3D printing? Spheres are uniquely challenging because they can only intersect with a flat surface on exa...
The surface of a sphere is just like any curved surface when 3D printed – they are formed by flat layers on top of each other that simulate the look of a curved surface. To make spheres look nice, the conventional wisdom is to reduce the layer height, thus increasing the Z-axis resolution. Just this single step should already help massively in the ...
We have already said that printing with supports is still problematic, but you can still do this method and get a flawless product if your printer has dual extruders. More specifically, you will want to print the support structures with dissolvable filament like PVA or HIPS. This eliminates the issue of supports leaving blemishes upon removal. Even...
The more common recommendation is to simply split the sphere in half and to print the spheres separately with the flat side facing down. This avoids the issue of having the layers fall apart or the surface of the sphere getting ruined by supports. The hemispheres can then be glued together during post-processing. There are a couple of cardinal rule...
Whether you printed the sphere as a whole or split it in half, you will have to do some post-processing to make it look great. For spheres printed whole, the first order of business is to remove the supports. Hopefully, you were able to use dissolvable material. If not, a sharp utility knife or X-Acto knifeshould help you remove as much of the supp...
Spheres are some of the most common 3D shapes in the real world, making them prime options for designing 3D models. Unfortunately, 3D printing a sphere can be a surprisingly daunting task. While it’s possible to 3D print an entire sphere with lots of supports, it is far more common to split a sphere into two hemispheres. This is easier in terms of ...
Jul 25, 2021 · 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.
The issue is that a FDM 3D printer can do very well with 0 to 45 degree overhangs, and rarely can do well above a 65/70 degree angle. A sphere goes from 0 to 90 degrees on that curve. 0 meaning a vertical line and 90 meaning a horizontal line.
Mar 14, 2023 · In this blog post, we will explore the world of 3D printing spheres, including the benefits and challenges of printing spherical objects, tips for designing and printing spheres, and some interesting applications of 3D printed spheres.
Spheres are never really going to look good unless you print them in two parts, but at least they'll look better. If you really want to, you can go to 3DHubs and get it SLA or SLS printed for a flawless finish.

I've been considering buying a dual extruder primarily to print complex objects needing supports (like bones), so I can dissolve the supports in water. Do you have some recommendations for a dual extruder? Also, are water-soluble filaments available for PLA? I had read somewhere that they only worked with ABS.
