3D Glass Solutions Overview

3D Glass Solutions is a US pure-play glass foundry. It turns its patented APEX® photosensitive glass-ceramic into three-dimensional microstructures, through-glass vias (TGVs), integrated passive devices and glass-core substrates for semiconductor packaging. When APEX is exposed to UV light, the patterned regions turn into ceramic. These regions are then etched away in dilute acid, leaving fracture-free vias and cavities in the surrounding glass. The company makes RF and millimetre-wave filters, couplers, antennas-in-package and substrate-integrated waveguides for defence, aerospace, 5G/6G and automotive radar customers. It is now repositioning around glass-core substrates and 3D heterogeneous integration (3DHI) for AI and high-performance computing. Its backers include Intel Capital, Lockheed Martin Ventures, Applied Ventures (Applied Materials), Corning, Nagase and Walden Catalyst. In 2025–26 the company moved from a small US foundry to an international manufacturing platform. It is building a ₹1,943.53 crore (about $230 million) advanced-packaging and glass-substrate plant in Odisha, India, with Indian central and state subsidies. It has also signed a tripartite MoU with Intel and the Government of Odisha for a proposed glass-core substrate complex of about $3.3 billion.


What the company does. 3DGS designs and manufactures glass-based electronic packages, passive components and substrates. Its core is the APEX® glass-ceramic platform, a lithium-aluminosilicate photo-definable glass. Under UV exposure and thermal treatment the exposed regions crystallise into a ceramic phase, which etches much faster than the unexposed glass. This lets 3DGS form high-aspect-ratio through-glass vias, cavities, channels and suspended structures without the micro-cracks that laser drilling can cause. Metallisation, redistribution layers and embedded passives are then added to make finished devices or substrates.

Company self-description. In its press materials, 3DGS calls itself "a world-class expert on the fabrication of electronic packages and devices using photo-definable glass-ceramics." It says it uses its product solutions to provide device manufacturing and systems integration services for standard and custom products, and that it gives customers complete glass-enabled systems integration services. Bloomberg's company description has three strands: foundry services for 3D heterogeneous integration, glass microstructural parts, and glass-based integrated passive devices.

Independent characterisation. 3DGS is best understood as a specialty-materials foundry. It is now becoming a platform supplier of glass-core substrates and advanced-packaging (ATMP) services. It has three revenue engines at different stages of maturity:

  1. RF / microwave / mmWave components and integrated passive devices (IPDs). These are the historical revenue core: bandpass filters, diplexers, couplers, baluns, air-filled and electromagnetic substrate-integrated waveguides (AF-SIW / eSIW), and antenna-in-package structures. Customers are mostly defence primes, aerospace, satellite communications and 5G infrastructure. Lockheed Martin's investment and the AS9100 certification point to defence demand.

  2. Glass foundry and 3DHI services. Custom design-to-manufacture work using APEX and, under licence from Corning, HPFS® fused silica. Process design kits (PDKs) are published so customer designers can work to standard rules. 3DGS is a named partner in DARPA's Next-Generation Microelectronics Manufacturing (NGMM) programme, run through the Texas Institute for Electronics (TIE) at UT Austin.

  3. Glass-core substrates and advanced packages for HPC/AI. This is the growth vector. Products include glass FCBGA substrates and packages, glass interposers with embedded passives and silicon bridges, and 3DHI modules. They are to be made at volume in Odisha on 510 mm × 515 mm panels.

Revenue model. The product/service mix is not publicly disclosed. Based on disclosed activities, revenue comes from (a) product sales of standard and custom RF devices, (b) non-recurring engineering (NRE) and foundry services for custom designs, (c) government R&D and programme funding (DARPA NGMM; a small 2022 grant recorded by Dealroom), and (d) long-term supply contracts. Preqin describes the HPFS glass business as running on long-term contracts, with prices negotiated on complexity and volume. Licensing income is not disclosed. 3DGS is a licensee rather than a licensor in its main disclosed IP agreement, the Corning TGV licence.

Value-chain position. 3DGS sits between glass and materials makers (Corning; its own APEX formulation) and chip designers, OSATs and system integrators. It overlaps with substrate makers (Ibiden, Unimicron, Absolics) and with OSAT-style assembly and test. Through the Odisha project it is integrating forward into assembly and packaging: the Indian plant is described as a vertically integrated "advanced packaging and embedded glass substrate ATMP facility."

Customer types. Defence primes and government agencies; aerospace and space/satcom OEMs; RF front-end and telecom-infrastructure suppliers; automotive radar suppliers (HPFS substrates for 70–150 GHz); photonics and datacentre interconnect developers; HPC/AI chip and chiplet integrators; and academic and government labs using 3DHI foundry services. Named customers are not publicly disclosed.

End markets served. Aerospace and defence (radar, electronic warfare, satcom); 5G/6G telecom; automotive radar; datacentres and AI/HPC; photonics; and medical and bio-sensors, plus quantum-dot sensors.

Strategy

Stated strategic themes. Company and investor statements from 2021 to 2026 repeat four themes:

  1. Volume manufacturing. Every financing since 2021 has been tied to "high-volume production." Mandava frames the Indian expansion around the idea that scale matters as much as technology.

  2. From RF passives to the AI substrate. The positioning has moved from "glass-based 3D passive RF devices" (2021) to "3D integrated passive solutions for RF, photonic and datacenters" (2023). It is now "advanced glass substrates and semiconductor packaging" for AI and HPC (2026).

  3. Glass as a 3DHI platform. Glass is presented as the substrate for heterogeneous integration, combining RF, photonic and digital die with embedded passives and vertical interconnect. NGMM participation supports this.

  4. Global scale through subsidised capacity. The company is using India's ISM incentives, which cover roughly 75% of eligible capex, and Intel's demand and know-how to build volume capacity it could not fund on its own balance sheet.

Financial Narrative

3DGS is a private company with no public reporting obligation. It has not published an income statement, balance sheet or cash-flow statement for any fiscal year. Revenue, gross profit, operating income, EBITDA, net income, EPS, margins and returns ratios are therefore not publicly disclosed. One web-analytics provider (Similarweb) places annual revenue in a $15–25 million band. That is a third-party model estimate, not a company figure.

The financial data that can be documented are the company's capital raises and the funding plan for the Indian project.

Disclosed equity financing by calendar year

Intel Capital made further investments totalling $8 million across two rounds after March 2025 (Reuters). The round sizes, total proceeds and timing of those 2025–2026 rounds are not publicly disclosed.

Odisha ATMP project funding plan (INR crore)

The plan is fully funded by equity and subsidies, with no external debt envisaged at this stage (ANI / MeitY, April 2026). Central and state support of ₹1,198.5 crore covers about 75% of eligible capex. In US-dollar terms the project is about $230 million (Walden Catalyst). One trade outlet put it at "about USD 21 million"; that figure does not match the INR amount and is incorrect.

Commentary

Revenue trajectory. Revenue figures are not publicly disclosed. The qualitative signals point to a business that was moving from development to commercial scale before 2023 and remained small through 2026. Investors described an "accelerated revenue growth strategy" in 2021 and 2023, and in 2023 management said it was building "high-volume" US capacity. The headcount, about 69 in September 2026, implies annual revenue in the tens of millions at most.

Capital intensity inflection. Committed capital has grown by orders of magnitude. Total disclosed equity raised from 2021 to 2023 was $54 million. The Odisha ATMP project alone is ₹1,943.53 crore (about $230 million) and needs ₹745 crore (about $85–90 million) of promoter equity. The proposed Intel–3DGS glass-core facility is about $3.3 billion. 3DGS's share of that $3.3 billion is not publicly disclosed, and one press summary puts Indian subsidy support at about $330 million. The equity need for Odisha alone is far larger than anything 3DGS has raised publicly. That implies new capital, possibly from strategic investors such as Intel and possibly at subsidiary level, which has not been publicly disclosed.

Balance sheet and leverage. Not publicly disclosed. The Indian project plan has no external debt, which suggests the group is not relying on project finance in the near term.

Analyst Conclusions

Management guidance. 3DGS gives no financial guidance. Its operating targets are commercial production at the Odisha ATMP unit by August 2028 and full volume by August 2030. Annual capacity is planned at about 69,600 glass panel substrates, 50 million assembled units and 13,200 3DHI modules. The separate Intel–3DGS glass-core and HDI substrate facility, about $3.3 billion, is to be built in phases over five to six years.

Consensus expectations. No sell-side coverage exists. Third-party forecasts for 3D glass substrates range from about 13% to 29% CAGR through 2032.

Bull case

  1. Intel validation turns into volume. Intel has shifted toward external glass-substrate sourcing and co-signed a ~$3.3 billion facility with 3DGS. If definitive agreements follow, 3DGS gets an anchor customer that most glass start-ups lack.

  2. Subsidised capacity lowers capital risk. Central and state support of ₹1,198.5 crore covers about 75% of eligible capex at Odisha, with no external debt. Return on invested equity could be high once the plant is loaded.

  3. Dual-use moat. The APEX patent estate, AS9100 RF heritage and DARPA NGMM role give 3DGS defence and RF revenue that pure HPC glass entrants do not have. That cushions the period before AI substrate demand matures.

Bear case

  1. Too small, too late. With about 69 staff and volume output from 2028–2030, 3DGS could find the HPC glass-substrate market already shaped by Absolics, Samsung Electro-Mechanics and Chinese panel makers.

  2. Single-partner dependence. Intel's glass strategy has changed course more than once. A shift back toward in-house glass at Rio Rancho or Chandler, or a change of Intel leadership, could strand Indian capacity.

  3. Capital and governance overhang. Odisha equity needs far exceed what 3DGS has publicly raised. The Tan–Walden–Intel links invite scrutiny that could slow or complicate Intel's commitments.

Analyst verdict

3D Glass Solutions has reached the most consequential point in its twenty-year history. For most of that time it was a small, technically distinctive Albuquerque foundry. Its patented APEX® photosensitive glass-ceramic produced fracture-free through-glass vias and low-loss RF passives for defence and telecom customers. The financings of 2021–2023 ($54 million in announced equity) and a 2021 burst of industry-first PDKs made it a credible specialty supplier. They did not make it a volume player.

The events of 2025–2026 changed that. India's Semiconductor Mission approved a ₹1,943.53 crore Odisha ATMP and glass-substrate plant, about three-quarters subsidised, and construction began in April 2026. A month later Intel signed a tripartite MoU for a ~$3.3 billion glass-core substrate complex. Together these give 3DGS something rare among glass-substrate start-ups: subsidised capacity plus a top-tier anchor partner, arriving as the industry expects glass to enter AI packaging between 2027 and 2030.

The asymmetry runs both ways. 3DGS is tiny, at about 69 employees, and publishes no financials. It is late against Absolics and Samsung, heavily dependent on one partner whose strategy has wavered, and tied to Intel through relationships that attract governance scrutiny. Execution risk is high on three fronts: building a first-of-kind panel-scale glass plant in a new region, funding equity well above past raises, and qualifying products with demanding HPC customers.

On balance, 3DGS is a high-option-value, high-execution-risk platform. Its intrinsic moat lies in patented process know-how and dual-use RF and defence credentials. Its upside depends on converting Intel's MoU into binding offtake and capital. Over the next twelve months, definitive Intel agreements, a well-subscribed new equity round and on-schedule Odisha construction would strongly validate the strategy. Delays on any of those would point to an RF specialist overreaching into a capital-intensive substrate market dominated by conglomerates.

SWOT Analysis

Strengths

  • Proprietary core material: APEX® photosensitive glass-ceramic is a registered trademark and patented process, enabling fracture-free TGVs and 3D microstructures
  • Large patent estate for a company of its size: Project backers cite more than a hundred patents on the glass-ceramic packaging platform
  • Strategic investor syndicate: Intel Capital (B1 lead, 2021; further $8 million in 2025–26), Applied Ventures, Corning, Lockheed Martin Ventures, Nagase, Walden Catalyst (C lead, 2023)
  • Defence-grade quality and programme access: ISO 9001 / AS9100 foundry; named DARPA NGMM partner
  • Design-ecosystem enablement: Industry-first glass-ceramic IPD node, AF-SIW PDK and HI node (2021); eSIW PDK (2022)
  • Heavily subsidised expansion: ₹1,198.5 crore of central and state support on ₹1,598.33 crore of eligible capex; no external debt
  • Experienced scaling CEO: Mandava co-founded Centillium (IPO) and Beceem (sold to Broadcom) and ran the Cadence IP Group

Weaknesses

  • Very small organisation: 69 employees as of 30 September 2026 (Tracxn)
  • No financial transparency: No audited financials, revenue or segment data publicly disclosed
  • Late to volume HPC substrates: Odisha commercial production targeted August 2028, full volume August 2030; Absolics was ramping in 2025
  • Funding gap against ambitions: ₹745 crore of promoter equity needed for Odisha, against $54 million in publicly announced equity raised in 2021–2023
  • Leadership turnover in the scaling phase: Three CEOs since 2017 (Flemming → Popovich → Mandava)
  • Reliance on licensed material for HPFS products: Fused-silica TGV process licensed from Corning, which is also a potential competitor

Opportunities

  • Intel as anchor customer and partner: ~$3.3 billion Odisha MoU (29 May 2026) with Intel supplying process know-how
  • Fast-growing market: One estimate projects 3D glass substrates growing from $425.6 million (2025) to $2.56 billion (2032), a 29.2% CAGR
  • AI/HPC adoption window: Industry analysis points to a 2027 launch and scaling toward 2030
  • India's semiconductor build-out: ISM has approved 10 projects worth about ₹1.6 lakh crore; India's market is projected to roughly double by 2030
  • US defence 3DHI demand: $1.4 billion NGMM (DARPA $840 million plus Texas $552 million) building a 3DHI prototyping base
  • Forward integration into ATMP: Odisha assembly line serves organic and glass packages, so packaging revenue can come in before glass substrates fully ramp

Threats

  • Well-funded Korean competitors: SKC putting more than half of a ₩1 trillion capital increase into Absolics; Samsung moving its glass project to a business unit for a 2027 ramp
  • Chinese fast followers: BOE and Visionox reported to be narrowing the gap (June 2026)
  • Intel strategy volatility: Intel's glass plans swung between in-house work (Chandler pilot, possible Rio Rancho) and external sourcing in 2025–26
  • Governance scrutiny: Reuters analysis of Tan's Walden-linked deals; the SambaNova conflict debate (February 2026)
  • Format and standards risk: Korean players contesting Intel on glass-substrate standards (April 2026)
  • Rival TGV process routes: LPKF LIDE laser process, Nikon photo-assist plating and Rapidus interposers could undercut the cost or yield advantage of photo-definable glass
