A. From start to finish, the process will take about 2 weeks. Most of this time is dedicated to the printing process and thus will vary depending on the specific model, size, and available materials. 

A.  Most of the prosthetic will be made from a hard plastic (PLA, PETG) to provide stability and support. Some prosthetic models require the use of a flexible plastic (TPU) in their construction. Other components include string, rubber elastic, screws, and glue. Any part of the prosthetic that will be in contact with skin will be lined with a foam padding for extra comfort. 

A. Unfortunately, there are some limitations to what the prosthetics are capable of. When bending one’s wrist or elbow, this drives the fingers of the hand to close. All fingers will close simultaneously, thus these prosthetics are better for picking up larger items and holding them. There is also a weight limit as the main force for closing the hand is created by tension from a string. Each individuals carrying capacity may vary depending on how strongly they can create this force. But as a general rule of thumb, these prosthetics will not be able to support more than a few pounds.
