If one of my friends needs this tool (preferably after I finish moving) I'll happily print one when I have time. Jeezus... some of you guys make trying to be nice a fucking ordeal. mnem"No good deed goes unpunished."
Fair dinkum. But honestly... thinking about how often I'd need that battery-powered scope...
0.2mm is the layer height I use when I’m in a hurry and I don’t care much what the print looks like. 0.12mm is “normal” and 0.08mm is what I think of as “fine”. Some modern slicers also offer adaptive layer heights that change with the geometry automatically.
NSFW (if you have multimeters around you)

Quote from: mnementh on August 02, 2020, 01:50:14 pmSLA is gorgeous. But what I HAVE is FDM. Defeats the whole "I have these tools, I want to make this, this is the easiest way" pro of 3DP. Also... making a 300mm rod would be much more expensive; both in resin and in terms of a machine with adequate build volume. That is a really big con to SLA. mnem Sure, but you will note I was replying to bd's comments on resolution for bogie sideframes.Personally, if I had needed to make a spacer for the connector, I would probably have found some metal washers or just drilled a hole in a piece of wood. But then I don't have a "hammer".

The fucking TOOL-DWAGON. Making stuff with my hands is literally my LIFE. I'm just saying that this isn't a job for for which 3DP is the best choice. I think made my case succinctly and I think convincingly - I certainly didn't think I'd be required to provide a full time and motion study, complete with cost of acquisition of materials study. What's next the fucking Spanish inquisition? You can choose to disagree or agree.And I'm saying that since I have the printer... and I have the filament... I would literally rather print it than be arsed to gather the materials to build it from stock. This is is very low-stress tool; the original is made of plastic, and I know from experience that a 3DP version will exceed the need. If I had some suitable rod handy, would I use it? Of course. I'd STILL probably print the handle tho.Maybe that is the difference here... experience. I don't have a lot of experience with 3DP; but I do have enough to be confident in its ability to make this tool. Will it make a heirloom tool I'd hand down to my grandkids? No. Will it make a tool I could... say... print up and mail to a friend who wanted to trim out one of those little voodoo 500MHz nuvistor oscillators and know it will do the job, and probably be around for the next one too, but not care if I never see it again? You betcha. mnemSo how much did this printer cost? How long did it take you before you learnt how to to use it and the CAD software you need to input data? How much space does it take up? These are just as relevant as the time taken to find, store and use stock and file handles.3DP may be easier for odd shaped tools but these will have longer design inputs and the strength of the prt may be questionable. We have have professional very expensive 3D prnters at work and while I am not directly involved in them I've been in contact with their output. To be usable for anything at all structural they need expensive filament and to get a good finish, post processing, both these need extended print times. We tend to use 3DP for prototypes and shapes that cannot be fabricated using stock materials and machining.They have their place but I don't think printing rod is the besy way.How about some pictures of the finished tool ?Oh sweet cheese and crackers... I LITERALLY answered every point you just made in the post you just quoted. The equivalent to my 3DP is the shop full of tools to form the rod and the store to go buy a file handle from. Apples-apples man.This is a low-stress tool; "the best way" is not needed here. All that's needed here is "the good enough way". If I didn't have any appropriate plastic tube, I'd print that too, because it would be good enough.If one of my friends needs this tool (preferably after I finish moving) I'll happily print one when I have time.

Too bad it's all in I assume Hindi or some other Indian dialect where I guess he explains what happens.

A proper rods/linear bearing design can get much higher res without breaking a sweat. Depends on just how much fettling you're willing to do to get everything perfectly square.Like xrunner; 3DP for me is one of many hobbies. It is just one that is also a tool. mnemmoo.
A Diggro eh, only Diggro 3DP I can find is the Alpha 3 which has a maximum print dimension of 250mm so you can't actually print a 300mm rod in one piece

What about SLA? Much smoother; the camera doesn't like to try to focus on it. 2mm pitch thread. The facets in the barrel are in the model, and aren't a printing artefact; the facets are 2mm wide.

It did make me crack up laughing when I heard that. Then I had flashbacks to chowing on veins and gristle out of the particular pie brand and shuddered slightly.

And there was another brand I can't remember now with a square of skin big enough to identify as pig, hairs included. *blerk*
