What features do you want to see on Sovol’s next printer? Still named as SV05?
I think any new model really needs to separate itself from the older models, perhaps even with a completely different form factor. Aside from minor differences, the current model lineup is more or less the same printer with a few changes here and there. There’s workhorses, IDEX, and larger size, but how about adding something built for speed? Personally, I would like to see either a CoreXY or a Cartesian printer with the bed moving up/down on the Z axis.
Not only would it be something that looks completely different but it would also be more stable, especially at very high print speeds. For example, a well built CoreXY can print at several hundred mm/s. If I tried that on my SV01, the glass bed is going to get thrown across the room.
Your idea is great, about the core XY machine, do you have any idea to increase the print speed of it if it is a direct drive 3d printer?
Got it! A good suggestion!
I’m far from an expert, but to my understanding, the easiest ways to increase print speed on most printers would be linear rails and a light weight carriage. The titan style extruder that comes with our printers is inexpensive, reliable and usually very easy to work with, but it is quite heavy. This would probably be the first place to look if the goal is the shed some weight. Extruders like the Sherpa and Orbiter are incredibly lightweight and get rid of the bulky NEMA 17 motor in favor of a geared NEMA 14 pancake motor.
Even without resorting to any fancy features, a core xy or cartesian with the bed on the z axis is capable of higher speeds simply because they don’t have to worry about a heavy bed with a lot of momentum quickly moving back and forth.
Orbiter uses a different motor, smaller than a Nema 14, but because of this quality matters on the motor AFAIK.
Creality has done a couple corexy builds but they aren’t able to take advantage of the benefits as much. The CR30 and the Ender 7 are corexy, but really don’t speed up well due to other design decisions. There’s claims that some of their other printers are, but they are just extrusion framed standard cartesians.
The hard part, now that Prusa is entering into the CoreXY ring it’s really going to be hard to contend in that market. That and the builds and engineering are more complex and costly.
Here’s my advice to everyone at Sovol on this: If you try CoreXY you’ll have to do it right. It strays far from the classic I3 clones, and is not anywhere near as simple. If you’re going to do it, look into how Voron Designs does it right, and how Tronxy does it wrong. On a good note, Voron designs has a bill of materials for their printers, so you can easily get an idea of the cost and complexity involved. Formbot also has done a corexy voron clone, and they don’t have a great reputation for it since it’s just not the same quality.
I was kicking this around in my head over the last few days.
Something far less in cost of goods sold like the corexy printers are…
Go with a design that either is enclosed out of the box, or is optimized to enclose and use for high temp printing. All metal hotend, bi-metal heatbreak, isolate power supply and board from the hot areas so that airflow in the control area can be separate from the enclosed area. Make sure hotend cooling fan is blowing away from the print area.
Many of us can mod to do this, many just want to print high temp first thing.
