DDD vs VELO: How DDD and Velo3D Compare (2026)

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.

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 VELO 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 VELO 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. Walnut is not an investment adviser.

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.

Velo3D makes metal 3D printers designed to produce parts with geometries that normally require support structures, aimed at aerospace, defence and energy customers printing complex components.

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.
• VELO drivers: Support-free printing of difficult geometries; Aerospace and defence demand.

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 VELO, velo3D is a small company that has faced serious financial pressure, including going-concern questions, restructuring and significant customer concentration.

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; VELO 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 VELO guides.

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.

VELO. Velo3D is a speculative position rather than an established manufacturer. Verify the current cash position, customer concentration and share count before drawing any conclusion, as all three have moved materially.

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); VELO shows business model Metal additive manufacturing systems and related services, end markets Space launch, defence, energy, financial position Has faced going-concern and restructuring pressure; verify current status, share count Has increased materially through capital raises; verify.

DDD and VELO 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.
