DDD vs NNDM: How DDD and Nano Dimension Compare (2026)
Last updated July 2026
Short answer
DDD is the larger of the two ($399.37M market cap): the incumbent the market prices for continued execution (-19.18x forward earnings, beta 2.70). NNDM is the smaller challenger ($313.66M), priced similarly on forward earnings (149.00x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
DDD vs NNDM: the tie-breaker metrics
Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | DDD | NNDM | What it tells you |
|---|---|---|---|
| Market cap | $399.37M | $313.66M | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | -19.18 | 149.00 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Beta | 2.70 | 1.00 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 34% of range | 27% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 1.52 | 0.64 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how DDD and NNDM affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. DDD and NNDM share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined DDD and NNDM exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does DDD (DDD) do?
3D Systems Corporation is one of the original additive manufacturing companies, offering a broad portfolio of 3D printers, print materials, software, and on-demand manufacturing services. It reports in two segments. Healthcare Solutions covers dental, medical devices, and regenerative technologies like bioprinting, and in Q1 2026 grew about 21% year over year (roughly $50 million) on strength in Dental and Med Tech, each up over 20%. Industrial Solutions serves aerospace, defense, and general manufacturing and grew more modestly (roughly $45 million). Total Q1 2026 revenue was about $95.5 million, up ~1% reported but ~11% excluding divestitures, and healthcare has grown to a scale that now rivals the industrial business.
What does Nano Dimension (NNDM) do?
Nano Dimension is an additive-manufacturing company whose original niche is 3D printing for electronics: its systems print circuit boards and additive electronics, aimed at rapid prototyping and specialized production for defense, aerospace, and research customers. Over 2025 it pursued an aggressive roll-up of the industrial 3D-printing sector, completing the acquisition of Desktop Metal in April 2025 and Markforged shortly after, in an attempt to assemble a broad additive-manufacturing platform spanning polymers, metals, and electronics. The company has long carried an unusually large cash balance relative to its revenue, and it reported roughly $237.8 million in cash, equivalents, and short-term deposits with no debt as of March 2026, which is the core of the investment case: a war chest that could fund restructuring, buybacks, or further deals.
DDD vs NNDM: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- DDD drivers: Healthcare as the growth engine; Margin recovery and cost discipline.
- NNDM drivers: Large cash balance as a cushion; Additive-manufacturing consolidation.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The central risk is that 3D Systems is a small, not-yet-consistently-profitable turnaround, so the thesis depends on execution that has not been fully proven. For NNDM, the central risk is that Nano Dimension is a speculative, loss-making company whose story hinges on capital allocation and restructuring rather than proven, growing profits.
DDD or NNDM: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick DDD if you believe its drivers more; NNDM if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the DDD and NNDM guides.
DDD vs NNDM: the full fundamentals
DDD. Figures are approximate and tied to the asOf date; verify live numbers before acting. Because 3D Systems is not consistently GAAP-profitable, traditional earnings multiples are not very meaningful, and the stock trades more on revenue growth, margin trajectory, and cash burn than on a stable P/E. As a low-priced small cap it can be volatile and sensitive to a single quarter. Treat this as a turnaround valuation, where the key is whether improving margins and healthcare growth translate into durable free cash flow.
NNDM. These figures are approximate, tied to the asOf date, and drawn from recent reports; verify live numbers in the latest SEC filings before acting. Because Nano Dimension is unprofitable, earnings multiples are not meaningful, and many investors instead watch its market value versus its net cash, its cash-burn rate, and how the board chooses to deploy the balance sheet. Governance, restructuring progress, and acquisition or divestiture news tend to move the stock far more than any conventional valuation metric.
Headline figures (approximate, Jul 2026): DDD shows revenue (q1 2026) ~$95.5 million, up ~1% reported (or ~11% excluding divestitures) year over year, segment mix Healthcare ~$50 million (up ~21%) roughly matched Industrial ~$45 million, gross margin (q1 2026, non-gaap) ~36%, up from ~30% a year earlier on richer product mix, profitability GAAP EPS loss narrowed to ~$(0.03); adjusted EBITDA slightly positive (~$2 million); NNDM shows business stage Loss-making additive-manufacturing consolidator; revenue modest relative to its cash pile and integration still in flux, cash position Roughly $237.8 million in cash, equivalents, and short-term deposits with no debt as of March 2026 (verify latest filings), profitability Unprofitable, with ongoing operating losses; a multi-phase plan aims to cut cash burn (Markforged sale expected to reduce it by about $15 million a year), recent m&a Acquired Desktop Metal (later Chapter 11) and Markforged in 2025; sold Markforged to Stratasys for about $42.5 million in 2026 while keeping metal binder jetting.
The bottom line: DDD vs NNDM
DDD and NNDM are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined DDD and NNDM exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between DDD and NNDM?
+
3D Systems Corporation is one of the original additive manufacturing companies, offering a broad portfolio of 3D printers, print materials, software, and on-demand manufacturing services. Nano Dimension is an additive-manufacturing company whose original niche is 3D printing for electronics: its systems print circuit boards and additive electronics, aimed at rapid prototyping and specialized production for defense, aerospace, and research customers. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is DDD or NNDM the better stock?
+
Neither is universally better. DDD is the larger incumbent; NNDM is the smaller challenger and looks pricier on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, DDD or NNDM?
+
On forward P/E (as of July 2026), DDD trades at -19.18x and NNDM at 149.00x, so DDD is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both DDD and NNDM?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of DDD vs NNDM?
+
DDD: The central risk is that 3D Systems is a small, not-yet-consistently-profitable turnaround, so the thesis depends on execution that has not been fully proven. Additive manufacturing demand, especially in industrial markets, is cyclical and can soften with capital-spending pullbacks, while healthcare growth must keep compensating for a slower industrial base. The company competes against larger and well-funded rivals, and pricing pressure could cap margin gains. Its history of losses, divestitures, and restructuring shows how hard sustained profitability has been. As a low-priced small cap, the stock is volatile and can move sharply on single quarters or news, and convertible notes plus any future capital raises create dilution risk. It pays no meaningful dividend, so returns rely entirely on the turnaround working. NNDM: The central risk is that Nano Dimension is a speculative, loss-making company whose story hinges on capital allocation and restructuring rather than proven, growing profits. Its acquisition record is troubling: Desktop Metal filed for Chapter 11 bankruptcy after the deal closed, and Markforged was sold to Stratasys at a substantial loss versus what was paid, raising real questions about M&A judgment. Governance has been volatile, with activist Murchinson winning board seats, a public fight over strategy, and the CEO replaced, all of which can distract from operations and unsettle strategy. The large cash balance could be eroded by continued losses or spent on further value-destructive moves. The 3D-printing industry has repeatedly disappointed on growth, competition from Stratasys and 3D Systems is intense, and the shares have a history of sharp volatility and prior reverse-split and dilution dynamics.
