Linksolution: Industrializing Additive Manufacturing Through a Digital Foundry Strategy
A shift from printer sales to manufacturing services based on large SLA, high-temperature FDM, and metal MBJ
0. Bottom line first
Linksolution should be viewed less as a simple 3D-printer hardware company and more as a digital foundry trying to expand industrial additive manufacturing into outsourced production services. Still, the cumulative 3Q25 operating loss of KRW 5.35 billion and operating margin of -101.1% are risks that must be checked separately from the technology story.
Official fact: Linksolution was founded in 2015 and listed on KOSDAQ in June 2025 through the technology-growth-company track. Cumulative 3Q25 revenue was KRW 5.291 billion, with product sales at 76.70% and service revenue at 22.91%.
Interpretation: The company is still hardware-sales heavy, but the Daejeon automated foundry and service revenue expansion could raise recurring revenue. The key is whether technology milestones translate into utilization and profitability.
1. Company overview and governance
Linksolution belongs to digital additive forming machinery manufacturing under Korea’s industry classification, with 3D-printer hardware and 3D-printing services as the two main pillars. Headquartered in Anyang, it has accumulated B2B references from customers such as Amorepacific and Hyundai/Kia.
Official fact: As of the end of 3Q25, CEO Choi Geun-sik owned 25.28%, or 1,410,569 shares. The employee stock ownership association held 0.73%, and minority shareholders held 73.99%. The board consists of three inside directors and one outside director.
In 3Q25, the former subsidiary Pure Additive was liquidated, leaving no consolidated subsidiaries and shifting the financial-statement basis from consolidated to separate. This reads as a move to reduce uncertainty in bio 3D printing and focus on mobility, defense, and aerospace.
2. Technology portfolio
Large photopolymer printing
Multi-laser, curtain-coater recoating, and floating-resin technologies improve cost efficiency for large mockups.
High-temperature industrial extrusion
The company has high-temperature dual nozzles, high-temperature chambers, and filament drying technology for materials such as PEEK.
Metal binder jetting
The source says Linksolution advanced MBJ to domestic first commercialization-stage TRL-8.
Interpretation: SLA and FDM support current industrial customers, while MBJ is the option for expanding from polymer-heavy sales into metal-part production. The launch and customer validation of MBJ equipment are the main technology checkpoints.
3. Market and business model
The global 3D-printing market is moving from prototyping to mass production. The source cites MarketsandMarkets data projecting the global market to grow from USD 16.2 billion in 2023 to USD 30.1 billion in 2028, a 13.16% CAGR. 3D printers and 3D-printing services are presented as about 71.13% of the total 2028 market.
| Category | 2023 | 2028 | CAGR | Meaning |
|---|---|---|---|---|
| Total 3D printing market | USD 16.2bn | USD 30.1bn | 13.16% | Industrial additive manufacturing expansion |
| 3D printing services | USD 5.7bn | USD 11.2bn | 14.36% | Above hardware growth of 11.73% |
Linksolution’s strategy is to move from one-off equipment sales to a digital foundry model that receives customer design data and produces parts. The planned Daejeon automated plant, with about 4,000 pyeong of floor area and KRW 50 billion total investment, is the core infrastructure and is scheduled for completion in the second half of 2026.
4. Financials and cash flow
| Item | Amount | Share | Note |
|---|---|---|---|
| Total assets | KRW 62,033,342k | 100.0% | Up 74% from year-end |
| Current assets | KRW 29,552,211k | 47.6% | Includes KRW 20.5bn cash and equivalents |
| Non-current assets | KRW 32,481,131k | 52.4% | Includes KRW 18.8bn construction in progress |
| Total liabilities | KRW 23,474,307k | 37.8% | Debt-to-equity ratio 60.8% |
| Total equity | KRW 38,559,035k | 62.2% | KRW 61.1bn capital surplus |
| Retained earnings | (KRW 24,970,848k) | -40.3% | Accumulated deficit |
| Product | Revenue | Share | Note |
|---|---|---|---|
| Product sales | KRW 4,058mn | 76.70% | Equipment sales core |
| Polymer SLA/FDM | KRW 2,092mn | 39.54% | Stable demand |
| Other monitoring etc. | KRW 1,966mn | 37.16% | Software and parts revenue growth |
| Service revenue | KRW 1,212mn | 22.91% | Core of foundry business |
| Total | KRW 5,291mn | 100.00% | Cumulative 3Q25 |
Official fact: R&D expenses were KRW 480,861k in 2023, KRW 1,832,533k in 2024, and KRW 1,446,124k in 3Q25. Ratios to revenue were 6.59%, 16.38%, and 27.33%.
Interpretation: Operating cash flow of -KRW 3.47bn, investing cash flow of -KRW 19.33bn, and financing cash flow of +KRW 29.50bn show a growth-tech pattern: funding from IPO and borrowings is being invested into future facilities and R&D before operations generate enough cash.
5. Risks
- Financial risk: cumulative 3Q25 operating margin was -101.1%, making profitability improvement urgent.
- Technology risk: CLIP and other high-speed printing technologies, or new metal-printing methods, could make existing SLA and FDM less competitive.
- Market risk: capex cuts or R&D budget cuts by auto, electronics, and defense customers could pressure equipment and prototype orders.
- Regulatory risk: safety education and workplace rules under Korea’s 3D Printing Industry Promotion Act can add costs.
6. Investment view summary
- Technology moat: large SLA, high-temperature FDM, MBJ, and 65 IP rights, including 50 domestic and 15 overseas.
- Business model: a shift from equipment sales to manufacturing services with recurring revenue potential.
- Partnerships: references with Hyundai Motor, Kia, LG Electronics, and the Agency for Defense Development support credibility.
- Key KPIs: MBJ commercialization, Daejeon plant utilization, service revenue mix, and cash burn.
