Frequently Asked Questions
I'm an amputee, how can I try one of your sockets?
Have your Prosthetist submit an order! In the meantime, check out our guide for amputees.
I'm a prosthetist, how can I try one of your sockets?
Questions prosthetic ask
How could 3DP replace everything I do as a prosthetists?
It can't. 3DP can replace the labor intensive portion of fabrication but there is no replacement for the hands and eyes of a certified prosthetist. For this reason Additive O&P only provides sockets to ABC and BOC credentialed clinicians (Sorry therapists, doctors, and all you cool dudes trying to make legs out of your garage).
Are there benefits to scanning instead of sending a cast?
Aside from time, money, space, cleanliness, and mobility of your practice there's really not anything to gain here.
Is 3DP cost effective?
Only if you like money. Our sockets are competitively priced with any other central fabrication facility. Want to slash your costs even further? Make your own socket IN HOUSE and let Additive O&P provide you with the files to print. For a fraction of the cost we will provide you with the same highly engineered socket file that is ready to withstand the forces of gait and appropriate force translation to the residual limb. Additive O&P would much rather you embrace this amazing technology rather than use us as a central fabrication.
Do I have to give up my plaster cast?
Of course not. If you choose to take a plaster cast we request that you provide measurements, alignment lines, and any additional fitting details.
What should I do with all my extra time, space and money?
We hear that bee keeping is nice, but we like to put our extra time and money towards helping amputees in the developing world. If you would like to contribute to the cause monetarily, donate your time, or see pictures of the Tylers making fools of themselves you should check out PHI by following the link here: www.prosthetichope.org.
What are the common issues people have had with your sockets?
The main concern people have expressed is that they are not clear. However, prosthetists have a rather large bag of tricks to get around this.
Which locks can I use for suspension?
Nothing is off limits. We have done mostly bulldog, ST&G, and Kiss suspension locks, but can easily incorporate any other style - just ask!
Can your sockets use Suction suspension? Do they hold vacuum?
They sure can! our sockets are water, and air, tight.
Socket Fabrication Questions
How can i determine if printed sockets are strong enough?
The same way you do with Vivac, Ameritrans, copolymer etc. Dynamic assessment of a diagnostic socket (of any material) is only appropriate when the device has been fortified with fiberglass. It is ultimately the practitioner's responsibility to make sure that the patient is safe on his/her prosthesis. Additive O&P has completed pilot studies to assure feasibility of its sockets and has seen fracture rates lower than that of Vivac. Further studies are in the works and we look forward to presenting our findings.
Are these sockets really strong enough to walk on?
They sure are. At the moment we are recommending them for patients under 225lbs. Talk to us if you have a larger patient - we can make sockets stronger by adding thickness or surface geometry.
Can I choose my Color? What colors are available?
Heck yeah! By default our sockets come in black, but we can order other colors at your request. This may increase cost and/or turnaround time slightly.
Can I put designs on the outside of the socket?
Yes! One of the benefits of 3D printing is that your imagination is the limit.
I had an idea for a ______, can you help me design/prototype it?
Absolutely! A handy side effect of learning how to 3D print and 3D model, especially with our backgrounds of Biomedical Engineering and Physics, is that we can help design, model, and 3D print prototypes. Drop us an email and we are happy to send you a quote.
Can I do my own prosthetic mods?
Absolutely! If you're already scanning and 3D modeling, you'll have the easiest transition into the Additive process. We will take your positive file and turn it into a socket file, adding our special blend of strengthening modifications. You can then print the file yourself or have us do it.
Will you awesome dudes teach me how to model and 3D print?
We sure will. We're in the process of putting together educational courses to do just that. In the meantime you can familiarize yourself with the end product by ordering a few!
Socket Modification Questions
How do I modify a socket that needs heat relief, trimming, drilling, etc?
We're so glad you asked! Our materials can withstand all forms of O&P violence.
What if I have very particular modification requests?
Allow us to accommodate your every need. Additive O&P is run for prosthetists by prosthetists and we speak the O&P language. We are happy to incorporate particular modification requests into a single device or keep your requests on file so that all of your sockets come back just the way you like.
What do I do If my socket needs adjustments?
For minor adjustments, feel free to heat, grind, drill, epoxy, or any other brand of O&P violence you usually impart on check sockets. For major adjustments, let us know what needs to be changed and we can do it digitally and send a new socket. One major benefit of 3D printing is that the original shape isn't destroyed like the plaster model in traditional fabrication.
Requesting a print and/or getting a quote
How do I send an order?
Our preferred method is to have you email a scan and work order to firstname.lastname@example.org.
Do I need to take measurements with my scan?
Yes. Scanners are fairly accurate, but things can occasionally go wrong with the dimensions. Having your by-hand measurements helps us ensure that the print file we produce is a perfect fit.
Can I buy the socket file and print it myself?
Yes, in fact that's what we prefer! One of the benefits of this technology is that you can have a socket 6 hours after you hit print. If we print the socket, then we still have to ship it to you. If you print it, the patient is up and walking days sooner.
3D printing isn’t ready yet, you guys are wasting your time?
Aside from being COMPLETELY INCORRECT, that's not even a question... How'd it get into FAQs?!
