What Is Medical 3D Printing?

This technology spans various disciplines such as materials science and biomedical engineering,and falls under non implantable forms(surgical guides,anatomical models),implantable forms(orthopedic prostheses,dental restorations),and bioactive forms(cell loaded scaffolds).

This technology is based on processes such as selective laser sintering and melt deposition molding,whereas materials such as titanium alloys and PEEK are selected according to requirement.Regulating layer thickness and porosity to be consistent with mechanical properties and biocompatibility,it has been widely utilized in precise surgical planning,tailor-made implant preparation,and regenerative medicine research.

Principle	3D printing technology	Printing process	Materials	Advantage	Limitation
Extrusion printing	Fused deposition modeling (FDM)	Squeeze heated plastic filaments through a nozzle and construct the parts layer by layer.	Polymers and composite materials.	Widely applicable and affordable, capable of producing sturdy components suitable for prototypes, anatomical models, and surgical guides.	There are obvious layer lines, which are not suitable for medical applications with high surface smoothness or complex details, and the material selection is limited.
Vat-polymerization	Stereolithography (SLA)	Using ultraviolet laser to cure liquid photopolymer resin and constructing objects layer by layer.	Using ultraviolet laser to cure liquid photopolymer resin and constructing objects layer by layer.	Can produce high-resolution, smooth surface components suitable for fine anatomical models, surgical guides, implants, and can manufacture complex geometric shapes.	Post treatment is required to remove excess resin and fully cure it, as the resin has limitations in terms of biocompatibility and mechanical properties.
Powder bed fusion	Selective Laser Sintering (SLS)	High power laser selectively fuses powder materials layer by layer into solid structures.	Nylon, metal powder, etc.	There is a wide range of material options, including biocompatible polymers and metal alloys for implantation, which can produce components with excellent mechanical properties and complex geometric shapes without the need for supporting structures.	The equipment is expensive and requires post-processing, and the surface finish is not as good as SLA.

• Orthopedics

Titanium alloy hip and knee prostheses were printed following CT scanning using a xyz 3D printer.The porous structure(50%-70% porosity)supports bone cell growth.In one instance,the rate of bone integration was 90% following 6 months of surgery,higher than 75% of conventional prostheses.

• Skull and Maxillofacial Reconstruction

The bone curvature and thickness are replaced using 3D printed implants.Implants made with xyz 3D printer's PEEK material are 40% lighter than normal titanium mesh,with an elastic modulus close to that of human bones,reducing postoperative pain.

• Surgical guide plate

In spinal nail fixation and other surgical procedures,3D-printed guide plate is able to 'search' and fit exactly on the bone surface,so the screw implantation error≤1mm.The resin guide plate printed by 3D printer costs only 1/5 of the price of traditional metal guide plates and is disposable to prevent cross infection.

Traditional drugs cannot compensate for the metabolic differences of patients.3D printing accomplishes custom-made therapy by controlling drug distribution and release rate.

The xyz 3D printer combines variable amounts of drugs with biocompatible polymers to print sustained-release multi-component tablets.As an elderly hypertensive patient tablet,the outer shell is released rapidly to control morning peak blood pressure,while the inner shell releases slowly to maintain drug action throughout the day.

• Human Skin Repair

Based on high-resolution imaging equipment,CT for hard tissues(0.5mm resolution),MRI for soft tissues,and oral scanners for dental,and data is stored in DICOM format,setting the stage for the processing to follow.

The material should be able to meet the requirements of biocompatibility,mechanical properties:

Based on the model and material selecting technology:SLS can be used for metal,with different laser power and scanning speed to create the 3D printing parts' density more than 99%.FDM is used for polymer materials,and nozzle diameter decides the precision.SLA is used for resin with precision printing.Bioprinting requires a clean room with temperature set to around 37℃.Post-processing is required subsequent to printing for achieving clinical standards.

Clinically used 3D printed components after quality check,and surgeons use them according to preoperative planning.Post-operative follow-up evaluation of the impact is done in the long term.

'one person,one model'enables the implants to be customized based on patients' needs, e.g., orthopedic implants for children produced by xyz 3D printer can maintain growth space.

Just produce complex human tissue,such as porous titanium alloy scaffolds for better efficiency in bone integration.

• Save cycle time and cost:

It only takes 24-48 hours for the xyz 3D printer to complete the production of 3D printing parts,and it is 30%-50% cheaper to personalize in small quantities than with traditional methods.

• Improve surgical safety and efficacy:

Preoperative models and guides reduce blind procedure,and accuracy of screw placement in complex spinal surgery has been increased from 85% to 98%.

• Material limitations:

Dozens of sole accepted materials exist,and the biomechanical properties of bio ink are insufficient.There is an elastic modulus mismatch of some metal materials with bones.

• Excessive cost and threshold:

High-precision xyz 3D printers are expensive,and the maintenance fees are very high with no professional staff.

• Lack of regulation:

It is difficult to authenticate customized products according to traditional standards,and the application process must be investigated.

• Bioprinting Challenge:

Bioprinted tissue has a short lifespan and it is difficult to generate elaborate vascular structures.

Case Study:A Life Changing Custom Skull Implant

Patient situation:

A young patient who has a tremendous skull deficiency resulting from a car accident.The traditional repair methods are difficult to fit properly and possess poor aesthetics.

Technical challenges:

• Inaccuracy in the anatomical fit:

Skull deficit up to 12cm×8cm,serrated edges and intricate curvature at the back of the frontal and temporal bones,where conservative vascular channels and nerve grooves have to be provided.Standard CT modeling has an error up to 2mm.

• Synchronizing morphology and function:

Implants need to achieve biocompatibility,mechanical compatibility(comparable elastic modulus with 10-30GPa of skull),and postoperative aesthetics simultaneously,and one procedure is difficult to balance.

• Limits of intraoperative adaptability:

Traditional restorations are of high stiffness and can't accommodate tiny anatomical variations during surgery,which can readily lead to poor fit or secondary damage.

JS’s Solution:

• SLA Preoperative Planning:

Leverage the high-resolution(0.02mm layer thickness)quality of SLA to print a 1:1 defect model of the skull from CT data and reproduce anatomical data.The surgeons can rehearse the surgery,identify the fitting border,and control the error to 0.3mm.

• SLS function and form unification:

Employ SLS technology to sinter the titanium alloy powder to create one-piece implant body.The contact surface is designed to have a porosity structure of 500-800μm(cancellous bone simulation)to realize bone integration.The surface is laser polished with roughness Ra≤1.2μm to provide enhanced aesthetic properties.A thin-walled structure of 0.5mm for intraoperative adjustment at the edge.

Achieve results:

The adhesion between implant and the edge of defect reached 99.5%,reducing the operation time by 40 minutes.CT scan at 3 months postoperation showed new callus formation in porous structure,and there was no rejection response in 6-month follow-up.The rate of bone integration was up to 92%,and the appearance of symmetry in skull was up to 96%.It solved the issue of fit and cosmetic in traditional methods,and the clinical effect was excellent.
