DIY Stuffed Animal Stuffing Machine?

My wife makes stuffed animals, pillows and other items that are fiber filled. She does it by hand and it is very time consuming, so I checked around for a used machine, something like what you see in the Build-A-Bear stores, but hopefully smaller and not too expensive (like video but smaller)


Not much that I can find and most are very large, you have to pick them up because no one will ship them and the absolute cheapest I saw was $750US, used and with no compressor.

I thought maybe I can make one but don't quite have a grasp on how to make the system that is actually blowing the fiber into the pillow or animal skin.

The top part does not seem overly complex, a hopper to put the fiber, and it has paddles that turn to break up the large pieces and also help send them down to where they would go to the injection system. This turning paddle/auger is usually motorized, but have seen some that have a hand crank.

When the system is on, the operator uses a foot pedal to allow the fiber to be injected or not as the user moves the bear around to fill different areas.

Does anyone have ideas on how the injection system works, or how you would make one? How does the fiber go from the bottom of the hopper, into the chute dispensing the fiber out of the nozzle? I have seen written that these machines use compressors but wonder how they get enough CFM from the large nozzle shown on the machine (looks at least an inch diameter)? And how does the fiber get from the hopper, to where the air blows it out the nozzle, again without losing CFM?

Anyone have experience with these machines? How about anyone with ingenuity, how would you go about making one of these machines? I figure between new and used parts, I should be able to make something that works for $250 or less. Having plans would be ideal but any helpful ideas would be very much appreciated.

The ones I've seen at BAB use an Archimedes screw to push the filler out the tube. It seemed a lot like the sausage stuffer attachment on a Kitchenaid.

Like this:

The rest of the machine is all about keeping the fluff bouncing around so it is slowly fed into the tube.

If you wanted to do this with air, I think you should check out an attic insulation blowing machine.

It has been years since I was in a build a bear, but I pictured it as being a Venturi with the foot pedal opening and closing a valve and a separate air system running constantly to keep the fluff mixing. I would think something with low pressure and high volume (think Gast blower) would be better for this application that a compressor.

I would be a bit wary of trying to DIY it until you can get a working proof of concept using cheap or no cost materials or else you'll end up reaching pretty close to that 750

How often does your wife need the machine? Some of the equipment rental places near me rent them. If it's one of those deals where she can rent it for a day or two and do a months worh of work, renting may make sense.

This video shows some of the details.


Looks like it just has a compressor that pressurizes the fluff box and the air goes out the fill tube taking fluff with it. The foot pedal is just a valve for letting compressed air in the fluff box. Seems pretty easy to make.

Most machines I have seen have a foot pedal to shoot fiber into the bear or pillow. When the pedal is not being pressed, I see the machine is still turning and tumbling the fiber.

So what is happening to the fiber in the auger? If someone does not press the pedal for more than a minute or 2, I expect the auger to compress the fiber with nowhere to go, causing a jam or burnt motor?

I mentioned the air compressor only because most listings either said comes with air compressor or air compressor not included.

I had not heard of Gast blowers before (or Regenerative Blowers). After a quick Google search, this could be an option, definitely need to look into this further.

This is a bit of a head scratcher. I understand the concept, but looking at these machines, they don't look like they have big 15HP compressors and tank. I am not even sure they have a tank, so might be a simple tankless compressor.

So where is it getting the CFM to blow air through that transfer tube into the tubing carrying the fiber. The tubing you see on most of these machines is usually an inch or more diameter?

Is it an HVLP compressor or turbine running these?

This is much bigger that the BAB machines, but does give some insight on how they work. This definitely looks like something High Velocity and guess the air is doing all the work....no auger involved.

Wow, learn something every day!:)
I have never even heard of them.

Build A Bear = Empty A Wallet

I don't know about where you guys are but in my area it looks like many stores closed down. I think it was a fad that kids loved and even parents thought was cool but because of the price, and also the novelty wore off, I don't see them in the big malls like I used to.

We've got a BAB store in our area. We took my (then 3 year old) son there last year when he was ready to give up his pacifier. He was able to put his pacifiers inside the Superman bear he picked out.

It's more of a special occasion kind of present than it is a "let me stop by the toy store and pick out a new toy for my kid" kind of present.

As an aside - my son was a paci addict. We limited use to certain times - he fell and got a boo-boo, time to get in the car seat, naptime, etc. When you'd ask him to give it up, he'd look at you and put one hand on it, almost like he was taking one last long drag off of it, and then he'd hand it over.

Yes, the auger would have to stop when you're not injecting fibers.

I think the biggest issue here would be the selection of the filler itself. Regular polyester stuffing comes in long strands that are sure to either wrap around an auger or clog around a nozzle. My guess is that you need something with short chopped strands. Like a "comforel" stuffing, which has short polyester strands that are wound into little spring like shapes.

Hi FMC1959 just wondering if you found a way to make one? I'm trying to find something myself and cannot figure one out

Here's a thought. If a lot of build a bear shops are closing, maybe call the home office, they have machines for sale?
YouTube lots of videos about making a fill machine.
