3D Printing Thread

[CC Ricers]

PLA actually works just fine for structural parts and doesn't emit noxious fumes like ABS does. I'm betting that's what the store is using Definitely check what model of printer they have and then research it to see the quality you can get out of it.

I've decided to go with 3D Hubs as I can easily find a local service that can print in ABS plastic there and delivery is fast (or I can also pick up). Now I'm trying to assess what is realistically and financially possible through these services. Like if I wanted to print a 20x20x1cm base for my custom case, how long would waiting times be and how much would it cost. As well as how well is the design suited for printing.

Oh, has anything been resolved with the 3D hubs controversy?

It seems it's still going on. But I would rather look for alternatives to 3D Hubs where I can outsource a printing service to a local printer. Any other places that are doing that, and are not misleading customers like 3D Hubs?

I believe there's one that soft launched in the wake of the 3D hubs stuff, let me double check its name.

-Edit- Right, it's MakerHub. Not sure how far along they are yet though.

There are a few and @Biowarejak mentioned one of them. The others are Treatstock, Print a Thing, MyMiniFactory, Freelabster, Phanes 3DP, and Paperless Parts.

Ah, I forgot Treatstock! I stumbled into this website somehow the other day. They have a good directory and filters for printing services. In the meantime I will continue designing the parts.

Ive only ordered once w/ tratstock but it was an utter shitshow. They kept me waiting for 2 weeks+ w/ zero contact before they told me the supplier had a broken printer. what should have taken ~ 1 week ended up taking about ~ 1 month.

 

[CC Ricers]

I hope it works out better for me. Being in a bigger city, I see many available local printers to choose from.

Total newbie to 3D printing here. I don't plan to buy my own printer yet but I'd like to try out a third party service. Aside from online services I found a local UPS store that has a 3D printer that people can use, It unfortunately does not say on their website what kind of materials are possible with it, or what model of printer it is. Has anyone used one from those stores? Is the quality good to prototype parts with? I know ABS plastic is one of the higher quality ones without going with a super expensive industrial printer. Just want a good material to build structural parts with.

Hi! I always use this platform for printing the items. There you can find 3d models and find Print Service with the suitable price, color and material btw, you'll not spend your time, you can place the order online

Interesting concept using laser holography for SLA...needs to be refined to get a better surface finish. I'm wondering if they can do a repeating pattern pretty quickly

looks interesting. doesn't look like it'd be able to print anything more complex than an object definable by 3 isometric planes ._.

Why do you think so? It seems to me like the resin will not cure if not three light-beams overlap, so you can easily choose to cure any voxel of your choice inside the build volume. The only issue I'm seeing is the potential for shadows when you cure something even though you don't want to, but that could be alleviated by printing in sets of layers.

 

[VegetableStu]

oh so only two laser projections are needed to cure that voxel? o_o I think I might have misunderstood that part in the first place ,_,

also is the part being printed prone to sinking while being printed? o_o

 

[iFreilicht]

No, I believe you need three, but it seems like they use a sort of pixel array for each dimension (like a projector, but with lasers instead of regular light), so you can just change where the 3 lasers intersect and where not.

In their demonstration, the edges that are formed were the only areas that all three beams went through. If only two beams were needed then the faces would have cured as well. However, I'm sure the curing is a function of both time and power, so you could just turn up the beam power and just require two beams.

But, as I questioned...if there are regular patterns in the structure, I'm wondering if they would be sequentially cured before the resin bath is drained to retrieve the finished part. For instance, a spoked wheel might be able to be formed by curing a pie section of the wheel and subsequent sections could be sequentially cured after to complete the whole wheel. Also, there are some very advance holographic techniques as well as steerable laser arrays that I could imagine being used to create very complex shapes.

I mentioned a while ago that I got a 3D printer that was large enough for a whole sff case. Well, I finally have parts together and will be printing and building one soon. I'm starting with a Ryzen 1200 and stock cooler until I am more confident in my printed designs. I am planning to upgrade to a Ryzen 2xxx 8 core when they come out in March, so this will be a mobile workstation for me. It will also use only ITX GPUs to stay under 4 L.

Are there any special considerations to note since the whole case will be 3D printed plastic? I am planning to use PLA and make sure the frame is 4-5mm thick for strength and most of the panels will be 2-3mm.

 

[Biowarejak]

I'd recommend PETg personally, but should be fine. Do your best to keep the load bearing PLA away from hot running components to avoid warping.

 

[entropy]

Good point. I ordered some PETG also. I'm not sure how well my printer will handle it, but it's worth a try.

If anyone is keen to print stuff let me know. Just picked up a Markforged Mark Two and will likely be offering a KMPKT printing service for community members in the not too distant future. At this point just taking interest in projects. You can find specs on the unit (including print envelope) here:

Has anyone ever "upgraded" (?) their 3d printer to use as a CNC or a laser cutter? I'm debating on making a modular mount for swapping the end to make my A8 printer into a multi-tool. The A8 isn't the best setup and has some quirks, so I should probably fix those before I try messing with lasers or drilling.
