ADSK vs DDD: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 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.

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. ADSK and DDD 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 ADSK and DDD 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.

Autodesk is a large-cap software company whose tools are the default in several design and engineering fields. Its best-known products are AutoCAD (2D and 3D drafting), Revit (building information modeling for architecture, engineering and construction), Fusion (cloud product design and manufacturing), and Maya and 3ds Max (media and entertainment). It serves roughly four end markets: architecture, engineering and construction (AEC), product design and manufacturing, media and entertainment, and a broad base of individual and small-business users.

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.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• ADSK drivers: Recurring revenue and high retention; Margins and free cash flow.
• DDD drivers: Healthcare as the growth engine; Margin recovery and cost discipline.

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 most-cited risk is valuation sentiment: software multiples compressed in 2026 amid debate over whether AI-native tools erode incumbents, and Autodesk fell about 16% year to date even while beating estimates, which shows the stock can move independently of results. For 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.

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 ADSK if you believe its drivers more; DDD 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 ADSK and DDD guides.

ADSK. Figures are approximate, tied to the asOf date, and use Autodesk's fiscal calendar (its year ends in late January), so verify live numbers before acting. At $240.26 the stock trades near 17x forward earnings and about 16x trailing free cash flow, well below the premium multiples it carried in past years, after a 16% decline in 2026. Analysts expect fiscal 2027 EPS of about $12.61 and revenue of about $8.3 billion; the next report, expected in late November, will show whether mid-teens growth holds.

DDD. With no GAAP profit and analysts expecting a loss of about $0.14 per share for 2026, earnings multiples are not meaningful, so the stock trades on sales (about 1.2x trailing revenue) and margin trajectory. The shares rose about 56% in 2026 through October 16 but fell about 20% in the past month, a reminder of how volatile a sub-$5 small cap can be. The early-November third-quarter report, with consensus near $97 million of revenue, is the next checkpoint.

Headline figures (approximate, October 2026): ADSK shows revenue (ttm) About $7.8 billion; fiscal 2026 was about $7.2 billion, up roughly 18%, latest quarter revenue (q2 fiscal 2027) About $2.05 billion, up roughly 16% year over year, net income (ttm) About $1.6 billion (GAAP EPS about $7.71), margins Gross about 92%, operating about 29%; DDD shows revenue (ttm) ~$388 million, ~flat yoy in Q2 2026, q2 2026 revenue / adjusted eps ~$94.6 million / -$0.04 vs ~-$0.05 expected, gross margin (ttm) ~34%, operating margin (ttm) ~-11%.

ADSK and DDD 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.
