3D printed casts aren’t yet available at every orthopedic office, but they are accessible through a growing network of providers across the United States and internationally. You’ll typically need a prescription from your orthopedic doctor, who either offers the service in-house or refers you to a provider that does. The process starts with your physician, not a retail store or website.
How to Find a Provider
The most reliable way to get a 3D printed cast is to ask your orthopedic surgeon or fracture care provider directly. Some clinics have adopted point-of-care 3D printing systems, meaning they can scan your limb and print the cast on-site. Companies that manufacture these systems have placed printers in clinics at no cost to the provider, making it easier for practices to offer the technology without a large upfront investment.
If your doctor doesn’t have a printer in the office, they can still prescribe a 3D printed cast through a partnering manufacturer. As one major provider has noted, any clinician can prescribe these devices even without a direct contract or on-site printer. The manufacturer handles the design and printing, then ships the finished cast to the clinic. Over the past decade, thousands of patients have been fitted through hundreds of referring providers using this model.
To start, search for orthopedic practices in your area that advertise 3D printed casting, or contact manufacturers like ActivArmor or Xkelet directly. Their websites typically list partnered clinics or can connect you with a nearby provider. Academic medical centers and larger orthopedic groups are more likely to offer this option than smaller general practices.
What the Process Looks Like
Getting a 3D printed cast involves three steps: scanning, design, and printing. A clinician uses a handheld 3D scanner to capture the exact shape of your arm or leg. These scanners are compact, portable devices that create a precise digital model of your limb in minutes. Some systems use structured light scanning technology, similar to what’s found in industrial design, adapted for clinical use.
Once the scan is complete, software generates a custom cast design tailored to your anatomy and injury. Newer algorithmic tools have cut this design phase from two to three hours down to roughly four to ten minutes. The cast is then printed, which takes about 10 to 12 hours, followed by a few hours of post-processing (washing and curing the material). In total, you can expect to receive your cast within one to three days of the scan, depending on the clinic’s workflow and whether printing happens on-site or at a central facility.
Timing and Injury Requirements
You probably won’t get a 3D printed cast on the same day you break a bone. Freshly fractured limbs swell significantly, and the cast needs to fit your limb precisely to work. Most providers apply a traditional splint first, then transition to the 3D printed cast about 10 days later, once swelling has subsided. This waiting period is standard practice, not a limitation of the technology itself.
3D printed casts work well for stable fractures of the forearm, wrist, and hand, which are the most common applications. They’re generally used for immobilization rather than for complex or unstable fractures that might need surgical hardware. Your doctor will determine whether your specific injury is a good candidate.
Why Patients Prefer Them
The practical advantages are significant. A standard plaster forearm cast weighs about 457 grams. A fiberglass cast comes in around 325 grams. A 3D printed cast made from PLA (a common printing material) weighs roughly 318 grams, making it the lightest option. That difference matters when you’re wearing it for weeks.
The bigger wins are comfort and durability. Traditional plaster loses its structural strength quickly under repeated stress. In lab testing, plaster lost nearly 60% of its holding force after a second round of bending and almost 80% after a third. PLA, by contrast, lost only about 2% after the second round and under 5% after the third, meaning it holds its shape far better over the course of healing.
3D printed casts are also breathable and waterproof. The lattice design allows air to circulate around your skin, which prevents the itching, odor, and moisture buildup that make traditional casts miserable. You can shower normally. Studies comparing patient satisfaction between fiberglass and 3D printed short arm casts found similar objective function, but patients consistently rated the 3D version higher for comfort, satisfaction, and perceived function. In one study, patients expressed a strong preference for the printed cast over conventional options.
Cost and Insurance Coverage
Cost is the biggest barrier for most patients right now. 3D printed casts typically range from $200 to $500 out of pocket, though prices vary by provider and complexity. Traditional fiberglass casts are cheaper upfront, often fully covered by insurance.
Insurance coverage for 3D printed casts is still catching up. The American Medical Association has approved temporary billing codes (category III CPT codes) for 3D printed medical devices, and the Centers for Medicare and Medicaid Services plans to reimburse some of these codes. However, these temporary codes don’t have a fixed dollar value assigned to them, so reimbursement happens on a case-by-case basis. In practice, this means your insurance may or may not cover part of the cost depending on your plan and how your provider bills the device.
Some manufacturers have worked to keep costs competitive by using affordable printing materials like ABS plastic and providing printers to clinics at no charge. Ask your provider about pricing before committing, and check with your insurer about coverage for custom orthotic or immobilization devices.
Regulatory Safety
The FDA regulates 3D printed medical devices, including orthopedic immobilization products, through its Center for Devices and Radiological Health. The agency has published specific guidance on technical considerations for additively manufactured medical devices, covering material properties, manufacturing processes, and quality standards. Devices that go through this regulatory pathway have met federal safety requirements, so look for products from companies that have obtained FDA clearance rather than unregulated alternatives.
