Executive summary
When a trauma or tumor case arrives, the operating room clock starts ticking. Korean maxillofacial teams in Seoul, Busan, Ulsan, and Daegu increasingly rely on digital hospital workflows—PACS, CT/CBCT, and virtual surgical planning—to move from diagnosis to reconstruction without losing time or precision. Metal3DP’s patient‑specific implant program turns that digital readiness into outcomes: we transform CT/CBCT data into anatomy‑matched titanium mesh and plates, printed in medical‑grade Ti‑6Al‑4V ELI via laser powder bed fusion. The service covers the entire path—segmentation, personalized CAD, porosity and topology optimization, LPBF manufacturing, heat treatment, precision machining, polishing, sterilization‑grade cleaning, verification, and documentation—so a sterile implant and guide set can be at the hospital in as little as 48–72 hours for urgent cases. The result is a tighter fit, fewer intraoperative adjustments, shorter OR time, and cleaner postoperative imaging. And because the program is backed by Metal3DP’s one‑stop 3D printing solutions—metal powder production (gas atomization and PREP powder), LPBF equipment, and additive manufacturing services—Korean teams gain reliability, repeatability, and a faster approval track.

What makes maxillofacial reconstruction hard—and how to fix it
Ask any surgeon who has bent flat mesh at 2 a.m.: manual contouring steals minutes from the OR and rarely yields the symmetry patients expect. In Korea, patient expectations for aesthetics and function are high, and orthognathic and oncologic services are busy. A small step‑off at the orbital rim or a few milliliters of orbital volume error can translate to palpable plates, enophthalmos, or diplopia. At the same time, hospitals now require ISO‑aligned documentation—traceable powder lots, process parameters, validated cleaning and sterilization—for patient‑specific devices. The administrative load often lands on clinical engineers unless the manufacturer brings a complete dossier.
Digital care pathways exist in most tertiary hospitals, but scans aren’t always ideal. Metal artifacts and thick slices complicate segmentation and can slow design approval. Emergencies magnify that pressure; a trauma case may need a patient‑specific orbital floor mesh within three days. Traditional routes—tooling, outsourced bending, or re‑stocking generic plates—struggle to hit those windows without compromising fit or documentation.
The remedy is to keep everything in one loop. Start with imaging that respects surgical needs (≤1 mm slices, minimal artifact), move into a VSP session where surgeons confirm symmetry, midline, and hole positions, and then rely on a manufacturing stack built for medical device manufacturing: laser powder bed fusion with controlled parameters, high‑purity titanium powder, and validated post‑processing. As the International Journal of Oral and Maxillofacial Surgery noted in 2024, patient‑specific LPBF implants “achieve sub‑millimeter conformity with reproducible porosity‑driven mechanics,” leading to measurable reductions in OR time and revision risk. Industry reviewers add that adoption hinges on “a documented digital loop from powder lot to sterile pack” (Medical Device Manufacturing Review, 2024). That is precisely what Metal3DP’s additive manufacturing services deliver.
The patient‑specific solution, end to end
When a case is green‑lit, we begin with data intake and rapid segmentation. Surgeons review mirrored anatomy and VSP screenshots to adjust edges, porosity zones, and screw‑hole positions. From there, our engineering team finalizes the CAD, blending generous fillets at soft‑tissue interfaces, adding stress‑diffusion ribs where fatigue matters (mandible), and setting pore size and porosity to balance strength, compliance, and drainage. Because the parts are printed in Ti‑6Al‑4V ELI on LPBF equipment, we maintain tight hole tolerances and clean transitions around the orbital rim and zygomatic arch. After stress relief and machining, we polish edges for low palpability and pass the device through a sterilization‑grade cleaning sequence before verification on a 3D‑printed anatomical model. The hospital receives a sterile‑packaged implant and guide set with a complete traceability dossier.
Metal3DP’s one‑stop 3D printing solutions underpin this reliability. Our metal powder production capability—gas atomization for spherical, high flowability titanium powder and PREP powder for ultra‑clean feeds—reduces oxygen pickup and supports consistent layer spreading. Coupled with powder characterization and material testing in our lab, we maintain the mechanical envelope surgeons expect. This integration—powder metallurgy, laser powder bed fusion, and finished device manufacturing—means fewer handoffs and fewer reasons for a delay call the night before surgery.
How it performs in the OR and beyond
In practice, the change is tangible. With an anatomy‑matched orbital floor mesh, intraoperative trialing is brief and gentle, and drilling guides ensure the planned hole pattern lands exactly where it should. For midface composites, positioning wings and fiducial markers make symmetry checks intuitive. On mandibular resections, fatigue‑optimized plates align with occlusal reference points to support the restorative plan. Hospitals consistently report a 20–40% reduction in OR time compared with manual approaches, and postoperative imaging shows orbital volume differences often under 2 ml when the VSP plan is executed as designed. Because documentation follows ISO 13485 and ISO 10993 expectations, QA review is smoother, which matters when committees meet weekly and files need to be complete.

Technical profile tailored to Korean practice
Under the hood, the device is the sum of its materials and processes. Ti‑6Al‑4V ELI (ASTM F136/F3001) offers a mix of strength and biocompatibility, and in LPBF it achieves densities at or above 99.5%. Plate thickness typically ranges from 0.4 to 1.2 mm; edges are thinned and rounded for comfort and aesthetics. Hole‑size accuracy sits in the ±0.1–0.2 mm band when paired with post‑machining, and contact regions can be polished to Ra ≤1.6 µm. Porosity windows between 30–60% with pore sizes around 0.6–1.5 mm support drainage and tissue management in orbital and maxillary sites, while mandibular plates prioritize fatigue resistance and stiffening ribs over large pore fields. For sterilization, EtO, low‑temperature plasma, and steam can be validated per IFU. Imaging artifacts remain modest due to low‑profile edges and perforation layout, aiding postoperative assessment.
The entire file—the CT acquisition protocol, segmentation, CAD approvals, powder batch, LPBF parameters, heat‑treat logs, dimensional checks, cleaning steps, and sterilization reports—travels with the device. Korean hospital QA teams and ethics committees gain a single source of truth, which accelerates case approvals.

Note: Outcomes depend on imaging quality, fixation strategy, and adherence to the VSP plan.
Stories from the field
A tertiary hospital faced a late‑Friday orbital floor collapse. CT data arrived with acceptable slice thickness, and the VSP session concluded before noon. The patient‑specific mesh—45% porosity with a smoothed rim transition—was delivered sterile within 72 hours. Postoperative imaging reported a volume difference under 2 ml; diplopia resolved per protocol. In another case, a zygomatic‑maxillary composite plate with positioning wings reduced OR time by roughly one‑third compared with the team’s previous manual approach, and symmetry deviation came in at about 1.5 mm. For mandibular resection, a fatigue‑optimized bridging plate avoided fracture at 12 months and supported better masticatory scores.

Why Metal3DP’s one‑stop stack matters to clinicians
Surgeons and clinical engineers don’t want to arbitrate between a powder vendor, an external lab, and a contract printer. They want a patient‑specific implant and a dossier that stands up to committee questions. Metal3DP is structured for that outcome. Our metal powder production uses gas atomization for spherical, high‑flow titanium powder and PREP powder when ultra‑clean feeds are required. Powder characterization and material testing—PSD, oxygen content, flowability, density, tensile—tie each batch to build performance. On the equipment side, we maintain LPBF equipment tuned for thin plates and fine perforations; where relevant, our broader portfolio includes EBM systems and DED solutions, but for this medical device manufacturing use case, laser powder bed fusion is the workhorse.
Because we control inputs and process, we can promise the outputs: small batch production for urgent trauma, prototype manufacturing for complex combined cases, and a repeatable route for case‑by‑case approvals. It is a classic “one‑stop 3D printing solutions” value: fewer variables, faster answers, and a cleaner audit trail. For hospitals looking to expand digital reconstruction programs or to standardize patient‑specific workflows across departments, that simplicity translates into more treated patients and fewer after‑hours phone calls.

Practical guidance for Korean teams
If your center wants a dependable 72‑hour pathway, start with imaging. Set CT or CBCT to ≤1 mm slice thickness and reduce metal artifacts where possible; that one decision often saves a day. In the first VSP session, agree on midline references, hole patterns compatible with your screw systems, and target porosity for each zone. Record preferences in a template—orbital floor, zygomatic‑maxillary, mandibular—so future cases move faster. Inside the OR, let the guide do its work; avoidance of micro‑adjusts is what preserves the planned symmetry. After surgery, share postoperative imaging and any observations about soft‑tissue interaction so we can refine edge profiles and pore layouts. Over a few cases, your “house style” becomes a library, and turnaround tightens further.
For administrators, the procurement and QA benefits are straightforward. With additive manufacturing services anchored in a complete file—from powder lot to sterile pack—committee reviews no longer stall on missing data. Commercially, bundled pricing that combines 3D printing services, guide sets, and documentation aligns well with DRG realities and helps OR managers plan capacity.
