3D Printer choices? FDM SLA CLIP

Post by pininy on Fri 22 Jan 2016 - 2:19

Hi,

Been quite busy with new place, finally got it leased out.

Anyway, I am new to 3D printers.

I am really new at it but after looking at Carbon3D CLIP technology i am SOLD, prints 25 to 100X faster. but it won't be out till 2018 or a stable or next gen one would be...

so i've two choices FDM or SLA.

MakerBot 5Gen + Scanner would be on my table... i and deciding MakerBot or FormLabs - Form2 SLA Printer,

The main concern would be the materials, resin is more dangerous to work with, when you have kids around. but it's enclose.

Whereas MakerBot can only do PLA, ABS would require higher temperature. but i think they will make new extruder for that.

SLA can provider very detail items, i like to produce some clear cockpits... but that is not the only things on my list to make.

for the formlabs material is costly about USD179 to USD250 not including shipping per litre. then PLA USD80 to USD100.

spoilt for choices.

I had conversion with formlabs since last OCT, their new product is due in 2016 which is now. I thought I had make a decision.

But after look at TED week on Carbon3d CLIP... i think no SLA printers will beat it..... so thus i am reconsidering getting FDM makerbot..

Then when Carbon3d is ready in the near future 2 to 3 years i will get that! it's printing speed and smoothness.. is amazing.!

Disclaimer: I am a total noob at 3D printing, even though we have a FDM printer (Lulzbot Mini) already since March 2015.

From what I read and saw on YouTube, unless you have a dedicated, well ventilated area, SLA printing may not be a good choice. Apparently it is extremely smelly, toxic and messy, in a bad way.

I would also say: don't worry what will happen in 2-3 years. There are so many models coming out every 3 month. The technology is improving all the time, and prices come down quickly. If you don't need a printer now, don't buy one. Buy what makes sense for you now. Maybe get a cheap 2nd hand printer first to get your feet wet, and upgrade to your dream model later.

The applications for FDM vs SLA are also very different. If you want to make a small, highly detailed, possibly clear part as you hinted, then SLA is your only choice anyway,
But a hobby-SLA will not be able to make large parts, or structural parts (e.g. replace a broken RC steering part), or parts that are strong enough to be used as tools.

On the opposite, FDM can not make anything "clear" (but it can do milky translucent), and the resolution is not good enough to make nice, detailed accessories for RC cars.

Beside the resin/filament, you should also consider other cost of other consumables.
Apparently the tray in some DLP-based SLA printers gets foggy and needs to be replaced regularly (at quite a cost!). Of course this depends on the exact printer you buy, so do your homework.
FDM is pretty robust nowadays, but there will still be wear-and-tear: bed surface, linear bearings, worn plastic parts, etc. Also rust is a severe issue in the high humidity here in Singapore, unless you can put the printer in a 24/7 aircon environment.

USD 80 for a roll of PLA is extremely expensive. A 1kg roll should be in the USD 30 area.
But: because of the weight shipping to Singapore is expensive, even from China.
Personally I do not use PLA, I use HIPS and ABS. HIPS for "scale parts", ABS for anything that requires strength or flexibility.

Also consider where your 3D models will come from. If you never done any 3D modeling then this will be a learning curve too, especially for making parts that can be printed successfully. There is lots of free/gratis software available, so at least on that front there shouldn't be any investment needed, other than time. Luckily with the help of the Internet it is easy to learn new  skills nowadays.

Incidentally next Tuesday/Wednesday there is a 3D printing conference and expo in Singapore (Suntec). http://inside3dprinting.com/singpore/2016/

good luck in your quest, Werner
