I tested 3D print tolerance fit for today’s article. Sometimes tolerance fit causes trouble when you want to print with assembly. Fortunately little doll house chair which I chose to test is very simple and causes no trouble to put two parts together. You just push in as you expected.
3D Print Tolerance Test
Test with Doll House Chairs
I was surprised when I saw the latest update of 3D Prints was April. Sorry for “long time no post” in the category (which is my favorite though), I’m printing and writing finally.
You may test 3D print tolerance fit quite often when you use a 3D printer. We develop 3D printing technology every day and there’re amazing (also bloody expensive) new printers.
But it’s not like printing on paper yet. You usually can’t “3D print” various colors at the same time. Therefore, you want to assemble parts with different colors.
If you’re a 3D printer user and have kids, you definitely have printed toys. I often print toys or things like that just to keep them myself, or to test printers and materials. And I was happy when I found this cute doll house chair consisted of two parts need to be fit.
3D print tolerance fit for assembly
Printable file is from Thingiverse as usual – special thanks to “jzero4242” for sharing. He has a collection of doll house furniture (more than 10 models) so check other items if you’re interested in these cute little things. I also like his doll house cabinet and definitely want to print it later.
- Hardware: Cubicon Style
- Software: Cubicreator 3.6.8
- Estimate time: 00:35 (ABS), Infill 10%
- Filament cost: 5.27g (ABS), when you print each back & base together
This doll house chair has only two parts to put together so you can assemble them easily. To print the parts precisely, I printed two backs at once then two bases later at once.
Sometimes you need glue or something to fix the parts even if there’re holes to be fit. But I didn’t use glue for these chairs.
I didn’t make any supporters either, when I save a GCode file to print. I think I needed them if this doll chair had longer legs. Also, you’d better have brim for the base due to printing condition.
Since I usually love to have different colors for assembled parts, I used two types of blues – darker one and lighter one. And I took a photo of the two chairs on my yellow book (far below).
My recommended hole tolerance
Maybe a few of you noticed that I designed a product only manufactured by my 3D printer – Secret Garden flowerpot. Since the flowerpot has a part inside to stick an animal marker, it needs to be considered “hole tolerance”. I made it 0.4 mm when I modeled the product.
I think the hole tolerance may vary. It can be affected by design – how it looks or what the feature is. It also can be affected by materials (filaments). From my experience, I can say (a bit more or less) 0.2-0.4 mm for 3D print hole tolerance is okay.
Today’s test for 3D print tolerance fit finished successfully. A bit too simple, so I have to be back with more complicated assembly and various colors next time, to give you more information.
