Post-Print Processing: Chastity

IMG_1011_edited.jpg

Manufacturing chastity devices isn't just designing, printing and shipping them out. There's a lot of manual work that goes into each and every one of the chastity devices that we print.

Why?

​We use the most commonly used 3D printing methods FDM, this is the cheapest and most widely adopted method. However, once the devices are finished printing, they aren't particularly smooth. The interface between the cage and the printing supports become very rough.

As you can see in the image below:

So what?

This presents two big issues. Although the cages are printed so there are no supports inside and therefore no rough edges which touches your intimate area . Rough devices aren't going to be comfortable, and they aren't very hygienic.  Every jagged piece of filament could cause injuries, and every knook & cranny is a potential breeding ground for bacteria.

How do we smooth out the devices?

There are two steps to finishing the device. First, we need to get rid of those pesky jagged edges. This is simply done by sanding the cage.

Regular sand paper works a treat.  Get the device semi smooth quickly, by using a sandpaper with a low grit (120), and work your way up to a smoother and smoother finish by using higher and higher grits (up to 600+). 
(Pro tip: higher grit = smoother product. Lower grit = quicker results)

This sanding process requires more man-hours than any other part of the process.

Keeping Clean

Once there are no rough edges to the touch, the device is almost ready. You can stop here and enjoy you cage as it is. However if you are planning on long term wear I would highly recommend coating your cage. With FDM it deposits the material in layers leading to millions of tiny knooks and crannies that are invisible to the eye, and impossible to tell by touch. Nonetheless, these are a breeding ground for bacteria. So, to fill in the "cracks", and to make the devices easier to clean, we then spray them with transparant sealant, or apply a generous coating of epoxy resin. This serves a few purposes: keeps bacteria out, makes the device easy to clean with warm soapy water and it gives the devices a glossier finish.

Transparent Sealant

The Acrylic sealant adds a very thin layer, filling in all the cracks. Once the device has been sprayed, they need to be left to dry.  The devices are then sanded again and sprayed once more to ensure a smooth and even finish. 

 

Epoxy Resin

Epoxy resin is new to KB3D, however, we are liking the results. The resin does a similar job, filing any cracks, but it's thicker - giving more strength and a higher quality feel.

How the process affects you:

Well, it makes the devices comfier, cleaner and look much better! Applying the finish isn't difficult, at all, but it's not all sunshine and rainbows... Applying the finish takes time. KB3D is managed part-time, around a full-time job, so time is precious.

 

In the interest of transparency, this drives up the costs.  That seems unfair to me, so if you have the time to finish the device yourself, I'll sell the device unfinished, or part finished at a significantly reduced rate! You'll be helping me out, bonding with your new device and making a great saving!

Make a saving!

We offer the device at three price points:

  1. Sanded and Sprayed - this is the fully finished product at the regular price

  2. Sanded - Make a partial saving by buying the product after it has been sanded, but before it has been sprayed.

  3. Unfinished - Fresh off of the printer!  I'll do none of the post-print processing, besides a quality check, and it's up to you to apply the finish yourself.  As a result, the price is massively reduced!

How do I apply the finish myself?

I've put together a step by step guide on how to finish the product yourself.  You can find this in our Guides section of the website.  Or click the button below to go straight there.
