3d printing

are there any 3d printing enthusiasts out there?
3d printers are going for as low as usd $200 (around sgd $300) (and even lower) on ebay
https://www.ebay.com/sch/i.html?_fro...inter&_sacat=0
one could even order them on the lazada
http://www.lazada.sg/shop-3d-printers/
you could find models ranging from $300-500 to perhaps 1k or more depend on models, manufacturers and functionality

if 1 google for it you would find even more local sellers
https://www.google.com.sg/search?q=3d+printer+singapore

has any 1 build a 3d printer from kit or has simply bought an assembled 3d printer and is actively using it to share your stories?

take a look at https://www.thingiverse.com/, it is a whole new 3d printed world out there

but i'd guess getting started has a rather steep learning curve etc. note 3d printing isn't 'child's play' even if you are 3d printing a toy.
nope, it certainly isn't as simple as putting paper in your inkjet or laser printer & press print

it can be rather *dangerous* as you may be dealing with highly flammable materials and the hot end is actually running non stop sometimes for hours with molten plastic at 200deg C (good enough for highly flammable things to catch fire)

but 3d printing makes possible some things for the ordinary man on the street which may otherwise be difficult or expensive to achieve

I was wondering why there isn't a 3d printing section here in hwz... I'm also keen in learning more before I make a decision to buy one... It doesn't sound easy though...

What questions are you keen to learn more? Maybe I can help! I just recently bought mine in JB it's way so much cheaper than SG. About RM759! Less than sgd$300😜

I guess it's a good budget to start with... Which 3d printer did you buy?

i bought mine directly from ebay
http://www.ebay.com/itm/Flsun-Prusa-...-/182621692509
but i'm so lazy that i've not yet assemble it yet

i think the cheaper and more well known makes are those prusa i3, reprap, rostock delta types of 3d printer. the more well known makers it seemed one of them is geeetech which makes prusa i3, reprap and rostock delta 3d printers.

i think there are some vendors who import geeetech printers from china and sell it locally. i think they may even provide warranty for it. buying from local may be somewhat pricier more like s$500 or more but u'd likely get more local support from the local vendor

the makes of prusa i3, reprap, rostock delta become popular and 3rd party (e.g. geeetech) makes them because prusa (Josef Průša the inventor and designer)
https://en.wikipedia.org/wiki/Prusa_i3
http://shop.prusa3d.com/en/

designed it and makes the specs/design all open source. a lot of 3rd party 3d printers becomes basically made from the same specs as prusa i3

there are basically 2 main types:
1) xyz cartesian 3d printers e.g. prusa i3, ultimaker & all the 'china clones' etc
http://shop.prusa3d.com/en/
https://ultimaker.com/en/products
https://www.ebay.com/sch/i.html?_nkw=prusa+i3&_sacat=0
2) delta 3d printers
delta printers started with Rostock delta 3d as an earliest original design
http://reprap.org/wiki/Rostock
https://www.ebay.com/sch/i.html?_nkw...delta&_sacat=0

delta 3d printers are adapted from the delta robot
https://en.wikipedia.org/wiki/Delta_robot
it is deemed (and actually true) to be more agile / faster moving than xyz cartesian 3d printers
but delta 3d printers some of them comes with a rather small base plate, this limits the footprint of the 3d print. but it seemed delta 3d printers some can print 'taller' models

in my google search i run into this manufacturer, but i've not seen or tried out their printers personally, hence not sure how 'good' they are.
http://www.reprap.cn/3d-printers-diy...27lheb0kuk0265
(note i'm not affiliated with any of the product manufacturers/ vendors, linking to those as examples)
(sidenote: note that ABS material needs a heated bed, the heated bed runs at 100 degC for ABS prints, good enough to boil water ! some vendors do not include heated bed or separate/extra prices for heated bed, so do check carefully, confirm with vendor). without heated bed, you would be 'stuck' with PLA material, but it is common and comes in many colors as well. filaments aren't cheap for both PLA and ABS)

note that a lot of the cheap ones ship as kits and you need to assemble it yourself. if you buy from local, i think the vendor may even offer to pre-assemble for a fee / higher price of the printer.

note also again that for 3d printers the hot end runs at some 200 deg C. hence, it is 'not for kids' (it is a fire hazard). do read more about 3d printing the 2 common plastics PLA and ABS filaments and their properties and their use in 3d printers. 200 deg C for a short while is normally 'not a big deal', but 3d prints can run for hours, that makes it a *real fire hazard* and hence dangerous (i.e. flammable materials near hot end can catch fire, esp if you are not monitoring it since it may print for hours)

for those who are keen to learn about 3d printing but isn't yet prepared to get or assemble one (from a kit), the softwares 'tools of the trade' it seemed are
1) openscad (or another 3d modeller cad applications)
http://www.openscad.org/
https://www.youtube.com/watch?v=eq5O...RO6dMGEMsw9-i3
note that this is command/script based, not graphical. it is quite like a programming language.
but the difference in this programming language is that it is declarative and it is based on CSG (constructive solid modeling)
concepts. so you need to learn the language which would include CSG syntax like sphere, cylinder, cube, extrude etc. normally for openscad if you press F5 it would refresh and redraw your model in the screen. then you need to export your model as an STL file. the STL file is the 3d model ready to be printed

2) slicer
i use slic3r
http://slic3r.org/
but i've read that cura (from ultimaker) is also very good is free and easier to start for the beginner
https://ultimaker.com/en/products/cura-software
the slicer 'slice' the 3d model and generate CAM (computer aided manufacturing) control codes that actually runs the 3d printer. it does so by 'slicing' the 3d models and generate 'tool paths' that tells the printer how to print the model as well as include instructions to extrude filament & control temperature.
the CAM instructions is actually used in CNC machines known as g-codes. hence the output file from the slicer is often suffixed with .gcode extension. some 3d printers allows you to put .gcode file on a sd-card, you'd just need to insert the sd card in the printer controller, chose the .gcode file from a menu & press print!

3) 3d printer (nope not yet 1st try the g-code simulator)
no 3d printer? no worries, 1st try a g-code viewer/simulator
http://jherrm.com/gcode-viewer/
http://diy3dprinting.blogspot.sg/201...olling-3d.html
http://gcode.ws/
http://www.dietzm.de/gcodesim/
https://www.thingiverse.com/thing:44286
these apps simulates the whole 3d print on your pc/notebook

so there you go, a free virtual 3d printer


you can find many very good examples of STL files and openscad files from https://www.thingiverse.com/

did more google searches
found an old thread
http://forums.hardwarezone.com.sg/ho...g-4634097.html
found a local group on facebook
https://www.facebook.com/groups/435722669874090/
found a local group on reprap's forum
http://forums.reprap.org/list.php?188

not affiliated with any of them, but listing some of those found in google searches:
found a .sg web for vendor ecomaylene3d printer
https://www.ecomaylene3d.com/
yet another (apparently local as well)
http://www.everyoneacreator.com/
https://www.3dprms.com/collections/3d-printers
more on lazada, but on lazada as like ebay some of them are shipped from overseas, hence check the vendor
http://www.lazada.sg/shop-3d-printers/
also run into this web, but uncertain if they are after all local based
https://iprice.sg/anet/

there are quite a number of 3d printing services, won't list many of them as the idea here is to run your *own* 3d printer and prints

Got a Flsun I3 and CREALITY 3D Ender-2
I will say if you are new to 3D printing, just get the small Ender-2, than move to bigger printer later time.

wow

but of course this is way beyond beginners, beyond 'professional' and possibly 'world record' calibre
designing that in the first place is no ordinary talent

even more examples
https://www.pinterest.com/thepalspin/3d-printing/
those 3d printed medieval buildings are not just 3d printed but 'professionally' finished which could involve very elaborate steps such as sanding, spray painting etc

ebay and
https://www.ebay.com/sch/i.html?_nkw...inter&_sacat=0
aliexpress
https://www.aliexpress.com/wholesale...ext=3d+printer
links on a search for 3d printers

plenty these days from below $200 usd to 1k or more, focus on the quality of parts, design, support (from manufacturer) especially for the 3d printer *kits* if looking for one

actually you don't even need a 3d printer to start

take a look at my post on 'virtual' 3d printer
http://forums.hardwarezone.com.sg/ho...#post109707892

you can also use more 'pro' and graphical editing 3d cad like audodesk fusion 360 etc
https://www.autodesk.com/products/fusion-360/overview

there are many 3d printing services in singapore
https://www.google.com.sg/search?q=3...ting+singapore
for 3d hubs some ship from overseas so do check
https://www.3dhubs.com/3dprint/Singa...psToCountry=SG

you can literally build your model , run it through the slicer, very importantly simulate your prints see for yourself that it is 'printable' and send it to one of the 3d printing services to print it for you. do take note that the 3d printing services normally gives you 'print-ability' guidelines such as walls should not be less than 2mm etc, actually there are lots more precautions for a successful print. hence you may need to work with the printing service especially if the prints fails

join the sg printing facebook group as well, it is run by a group of local enthusiasts
https://www.facebook.com/groups/SG.Reprap/
note that it is more for the sharing of personal 3d prints and (3d printer) builds/assembles
