EXTRACTED REQUEST: Is there another material that I do t have that would be perfect for this. As in easy to print and supper strong

RECOVERED CONVERSATION EXCERPTS
USER MESSAGES:
1. I have all kinds of material I can 3d print with. What would be a good material to print press break does with
2. What about pa6-cf 20 percent
3. What about pp
4. Do it

ASSISTANT RESPONSES:
1. For press-brake dies/tooling, the best printable material depends heavily on whether you're making 3-inch test sections or actually bending 10–16 ga steel with them. For the short tooling sections you're talking about, I'd rank common printable materials roughly: | Material | Press-brake tooling potential | Why | |. |. |. | | PA-CF / Nylon-CF | ⭐⭐⭐⭐⭐ | Tough, strong, fatigue-resistant; excellent choice | | PA-GF / Nylon-GF | ⭐⭐⭐⭐⭐ | Very tough; slightly less stiff but great impact resistance | | PC / PC-CF | ⭐⭐⭐⭐½ | Extremely strong/stiff; good compression performance | | PET-CF | ⭐⭐⭐⭐ | Stiff, dimensionally stable, relatively easy to print | | PETG-CF | ⭐⭐⭐½ | Good for prototypes/light forming | | ASA/ABS | ⭐…
2. PA6-CF with 20% carbon fiber is one of the better materials you could try for printed press-brake tooling. For short 3-inch tooling sections, I’d choose it over PLA, PETG, ASA, and probably standard PC for most experimental forming. The big advantages are high stiffness, good compressive strength, toughness, and much better heat resistance than PLA or PETG. The carbon fiber also helps reduce creep and deformation under load. The main weakness is that PA6 absorbs moisture aggressively, and wet PA6-CF can lose stiffness and print quality fast, so drying it thoroughly before printing matters a lot. For a 3-inch V-die or punch, I’d use very thick walls rather than relying purely on 100% infill—something like 8–12+…
3. I dug into the actual mechanical data, and I want to change my recommendation a little. For a 3-inch press-brake punch/die, especially where we're concentrating several tons into a small tool, your PA6-CF20 is already extremely hard to beat. The surprise contender I'd buy isn't PC-CF—it's PET-CF. My ranking for your application | Material | Stiffness | Toughness | Moisture issue | Printing | My use | |. |. :|. :|. :|. :|. | | PA6-CF20 | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | High | Medium | Maximum-load tooling | | PET-CF | ⭐⭐⭐⭐½ | ⭐⭐⭐⭐ | Low | Easy | Best all-around tooling | | PC-CF | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | Low | Medium | Impact/shock-loaded tooling | | PC | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ | Low | Hard | Not worth it here | | ASA | ⭐⭐⭐ | ⭐⭐⭐ | Low | Easy | Pr…

EXTRACTED KNOWLEDGE / HOW-TO
- *PA6-CF with 20% carbon fiber is one of the better materials you could try for printed press-brake tooling. For short 3-inch tooling sections, I’d choose it over PLA, PETG, ASA, and probably standard PC for most experimental forming.
- *Easiest → hardest: ASA → PP → PA6-CF20 → PC
- *PC is excellent mechanically, but it's the one I'd least want to print a big, nearly-solid die from unless there was a reason—it wants high temperatures and is much more prone to warping/internal stress.
- PC-CF — my pick for printed press-brake tooling
- PA6-CF20 — potentially excellent strength/toughness, but moisture and dimensional changes are more annoying
- Regular PC — very tough, but significantly more prone to warping
- ASA — easiest inexpensive prototype tooling
- PP — specialized compliant forming dies rather than rigid tooling
