HP Indigo Label Press, HP Indigo 20000, and 3D Printer Filament Rubber: Cost-Focused FAQs

The questions I actually get asked

Some questions keep coming up when people compare HP Indigo digital presses with desktop 3D printing. I'm not going to give you a generic 'hp-indigo' buying guide. As a procurement manager at a 52-person packaging company, I've managed a printing and prototyping budget of about $200,000 a year for six years, negotiated with 17 vendors, and documented every order in our cost tracking system. Every answer below treats cost as total cost, not sticker price. That's the part most machine comparison articles skip.

Here's what this guide covers:

• HP Indigo label press vs HP Indigo 20000 digital press
• Is an HP Indigo label press worth the price?
• Adventurer 4 3D printer and rubber filament
• 3D printer filament rubber mistakes to avoid
• How to clean a 3D printer nozzle
• Hidden cost of HP Indigo, lease vs buy, and what both machines share

What's the difference between an HP Indigo label press and the HP Indigo 20000 digital press?

An HP Indigo label press is made for label and flexible packaging webs, usually around 13 inches wide or less. The HP Indigo 20000 Digital Press is a B2 sheet-fed press, designed for folding cartons and heavier packaging. Both use HP ElectroInk and give you versioning and short-run flexibility, but they're not interchangeable. If you're comparing quotes, check substrate compatibility, sheet or web size, and ink coverage per job before you look at the monthly payment. A label press can run precision labels all day. But a carton job with variable data needs the bigger sheet and the heavier duty handling of the 20000. I made that mistake once: we quoted a folding carton job on a label press because the price per square foot looked better. We ended up with too much waste and a long conversation with the production manager.

Is an HP Indigo label press worth the price?

Worth it depends on your average run length and how many versions you run. It took me three years and about 250 order lines to understand that a low per-label quote is rarely the lowest total cost. For us, digital is the right call when a label run is under 30,000 labels or when the quantity and design change from one job to the next. At 500,000 labels, a flexo press wins on unit cost. HP Indigo's advantage is setup and flexibility, not raw speed. Also ask for a Delta E report if brand color matters. Industry tolerance for brand-critical colors is Delta E less than 2 per Pantone Color Matching System guidelines. Without a color sign-off process, a minor profile tweak can become a full reprint. We learned that with a customer logo that looked almost right until it shipped. The reprint cost us 6% of the project's margin.

Can the Adventurer 4 3D printer print rubber filament?

Yes, if by 'rubber filament' you mean TPU. The Adventurer 4 3D printer supports TPU, and the manufacturer's spec sheet—as of January 2025, at least—lists it as compatible. That doesn't mean you print it like PLA. Use a Shore hardness of 95A or lower for flexible parts. Slow the print speed down to around 20-30 mm/s, reduce retraction, and dry the spool first. My first TPU part looked like a lump of failed caulk. The second one came out usable after I lowered the speed and stopped the filament from curling. The machine can handle it. The settings are what need to be handled (note to self: run the temperature tower again).

What should you know before buying 3D printer filament rubber?

First, 'rubber filament' is usually TPU or another thermoplastic polyurethane. It is flexible but not the same as injection molded rubber. Second, the price is real. I've paid $30 to $60 per kilogram for quality TPU, depending on brand and lead time (this was around Q3 2024). Third, it absorbs humidity. If it gets wet, it turns into a stringy mess and clogs the nozzle. A dry box is not optional, at least in our shop. It works well for gaskets, grips, seals, and vibration mounts. But for high-wear parts that need exact dimensional stability, I still reach for the injection molding partner. Buy one small spool before committing to a bulk order. That's the advice I ignored when I bought three spools at once because the price-per-kg looked great.

How to clean a 3D printer nozzle without wrecking it?

If, like me, you searched 'how to clean nozzle 3d printer' and got conflicting advice, here's the version that works. Start by heating the hot end. Never pull material from a cold nozzle. For a partial clog, use the cold pull method: heat the hot end to the filament's print temperature, push material through, let it cool to around 100°C, then pull it out sharply. That tends to pull the clog with it. For a full clog, use a brass cleaning needle at temperature. Don't use a steel needle; it can scratch the inside bore. If you remove the nozzle, reinstall it at spec torque. I once left one hand-tight, and the filament leaked around the threads. That ruined the heater block. Spare nozzles are a few dollars. A damaged hot end is not.

What's the first hidden cost that catches HP Indigo buyers?

For us, it wasn't the press—it was the color management work before the press could run reliably. Profiles, Pantone references, substrate certifications, and operator training all add up. The press can hold a tight tolerance, but only if the input file is built for it. We didn't have a formal prepress review process. That cost us when a file with embedded RGB values printed a blue that was not the customer's brand blue. The rework took a week and a half. After that, we built a preflight checklist. It's boring, and it's the difference between a repeatable run and an expensive story. Budget maybe 10% of project cost for prepress testing if you're new to HP Indigo.

Should you buy or lease an HP Indigo press?

The numbers said lease. My gut said buy. We went with the lease in Q2 2024, and I still think it was the right move. Utilization came in lower than we forecast, and the lease let us hand some of that risk back. If your volume has been stable for several years and you have reliable maintenance support, buying might give you the lower five-year TCO. But the real calculation is not the monthly lease payment. It is the cost per good sheet, including service, ElectroInk, imaging oil, downtime, and waste. We also track a 'creative reprint' line, because design changes are part of our cost. That's an expense line most ROI calculators miss.

What do an HP Indigo digital press and an Adventurer 4 3D printer have in common?

More than people think. Both are digital. In HP Indigo, you don't pay plate charges per job. In desktop 3D printing, you don't cut a metal mold. That changes the cost floor for short runs and custom parts. What was best practice in 2020—minimum order quantities, long set-ups, big safety stock—is not the default in 2025. Workflows have shifted toward smaller batches and later design changes. But the fundamentals haven't changed: you still need the right substrate, the right print profile, and the right cost model. The machine gets the attention. The parameters and total cost are what make or break the project. That's the evolution I care about.
