Using a 3D printer to create disposable first aid tools


It is well known that 3D printing empowers normal people to unleash their creative potential. Along with that, however, these machines can also serve more practical purposes, and that’s clear in the increasingly technological world of modern medicine.

Whether you’re printing your own disposable first aid tools or looking to the future, the field of 3D printing in medicine is fascinating. We’ll explore both of these areas in this article to give you a deeper look at the options available now, as well as those to come.

First Aid 3D Printing Considerations

3d print choice

There are many things you need to consider when using a 3D printer to create disposable first aid tools. Whatever first aid job you attempt to do, you need to ensure that the tools you use are safe and suitable for the job, while also avoiding any procedures or treatments that should be left to professionals.

  • Materials: You can choose from a variety of 3D printing materials online, but not all of them are safe to use as first aid tools. Biocompatibility is a major factor here, and it’s something we covered in our 3D printing filament safety article.
  • Print quality: Rough edges, poorly bonded layers, and other 3D print quality issues can make your first aid tools uncomfortable and even dangerous to use, so you need to make sure your print quality is high.

Websites like Thingiverse are full of countless 3D models in all kinds of shapes and sizes. We’ve found some examples of the best 3D printable first aid tools available for free on sites like these, and you can see the results below.

3D printable splints

Splints are one of the oldest first aid/medical tools in the world. Used as a means of immobilizing joints, a splint is designed to allow your body to heal as quickly as possible without natural movement causing further damage.

This type of tool is especially important when a bone is broken. However, it can also help with other types of injuries, such as torn ligaments and muscles, and is used throughout the human body.

This simple Finger splint by i3dKC is designed for use on the fingers, while this Carpal tunnel splint by windy98 goes on your wrist, and both are great examples of this type of medical/first aid tool.

Dressing Forceps and Dispensers

Bandages are one of the most commonly used first aid tools, which means any first aid kit should make them accessible. A bandage dispenser can be a great option for those who find dealing with loose bandages frustrating, and that Khattoum Bandage Winder makes it very easy to apply bandages with the right pressure.

But how are you supposed to tie off the end of the bandage once it’s been rolled up? Bandage clips, of course! these Tensor bandage clamps by ksihota are a great starting point, providing an easy way to anchor your bandages without having to use annoying tape.

First aid boxes and kits

A well-organized first aid kit can prove invaluable in an emergency, taking the stress out of misplaced tools when someone needs help. When building your own first aid kit, it should be easy to figure out what it should contain, giving you the flexibility to find the perfect 3D model to print for the job.

You can find a range of 3D printable first aid containers online, from options like this little Pill box keyring by Mister_G to much larger first aid kits, like this video game inspired Halo Health Pack First Aid Kit by morleykert.

The future of 3D printing in medicine

the future of 3d printing

Healthcare is changing at a breakneck pace and the future of 3D printing in the world of medicine is a bit more exciting than the options available today. We’ve only chosen methods and ideas that are already in development or work in some form, but there are theoretical uses of 3D printing that go well beyond the areas below. .

3D printing of human organs

3D printed organs

Many people don’t know this, but 3D printable organs already exist, although this idea is in the very early stages of development. In 2019, Israeli scientists were able to produce a functioning rabbit-sized heart with blood vessels that acted like a real one, showing the world that this concept is a real possibility for the future.

3D printing an organ is surprisingly simple, with the 3D printer only performing the initial steps of creating a new organ. A frame that matches the shape of a desired organ is 3D printed with traces of tissue from an actual organ seeded into it, followed by an incubation period that allows cells in the tissue to multiply and grow. slowly grow around the frame.

This method is most commonly used for 3D printing hearts, although other methods are being developed for other organs. In the near future, this type of technology promises to solve the shortages of vital organs faced by people in urgent need of transplants.

3D printing of surgical models

3d printed surgical models

Surgeons have one of the toughest jobs in the world, with a single mistake having the potential to change a patient’s life or even kill them. For this reason, many surgeons will use practice aids to perform mock surgery before attempting the real thing, but it’s much easier when the tools available are a perfect match to a patient’s body.

3D printing should offer this opportunity to surgeons. As 3D scanners become more and more accurate, many hospitals are likely to adopt this type of technology to enable them to 3D print accurate models of their patients’ bodies in the future, which will bring many other benefits.

3D printable prosthetic limbs

Modern technology like 3D printing has the power to change the lives of people with physical disabilities like missing limbs. 3D-printed prosthetic limbs can be custom-made without as much expense as traditional options, while still offering wearers the ability to create prosthetic limbs that match their style preferences.

There are several companies that offer this type of medical tool to those who need it, but it will take some time before this area is perfected. Over time, modern 3D-printed prostheses provide those with missing fingers, arms, and legs with ever greater degrees of mobility and movement.

3D printing in the world of medicine

Over time, more and more 3D printing tools are being made available to doctors, surgeons, and even normal people at home. Of course, the real fun comes from designing and printing your own 3D models.
