Wondering why 3d printing didn't gain much traction in malaysia...

there are hardly any exhibitions that even have any actual 3d printing related products.

I went to metaltech and PRINTECH exhibitions this year. however, there wereless than 10 3d printing related showcases there, both exhibitions combined.

malaysian facebook groups are pretty much all the desperate 3d printing startups spamming there trying to get a customer or two.

heck, we dont even have a good filament store.

Actually 3D printing has been around a long time ago in the manufacturing sector but desktop 3D printers began gaining traction in Malaysia when the hype began around 2012, when the first desktop 3D printer became available. Thought now it is merely for the niche consumer market, creative designers, and makers a like.

The thing is there are many wannabe desktop 3D printing services that want to take advantage of the technology due to the low capital and limited accessibility but the reality is that the technology isn't fully appreciated and Malaysians aren't cultured enough to be makers/designers that takes advantage of benefits of the technology.

Also, the adoption of the technology not only requires technical knowledge but tons of problem solving and practical experience related to mechanical, electrical, material, and design aspect of the print. This is where beginners at 3D printing make the same mistake every time they start off 3D printing without prior knowledge. I have met several 3D printer owners whom simply bought themselves a 3D printer and not know what to do with it next and in some cases not be able to repair the printers when the problem occur.

I do have a Facebook for my 3D printing business (see my signature below) but I rarely spam as I am busy with my business and several projects. I have a ton of pictures showing completed prints but have yet the time to create posts now. I don't know which facebook group you are referring too but my concern is the quality aspect of the service and print quality provided by these startups. As far as I know, these startups tend make a quick buck and not care about the quality standards of their prints.

Actually we do have filament store but not the type that assures high material quality. They are mostly redistributors of china made filaments which I despise due to poor QA and varying color batches. The reason we don't have a proper filament store in Malaysia is due to two factors: Raw material and high production standards. 3D printers are limited to several thermoplastics and high quality filaments is a  must for continuous operation of the machine.

I did a small marketing analysis on the filament movement in Malaysia and found that it is not feasible to sell filaments to consumers due to low demand even at very poor margin. We just simply purchase our filaments from overseas from reliable suppliers.

Another problem is with the consumer expecting 3D printing services to be unreasonably cheap, since we were grown up with the notion that plastic is a cheap material but the truth is it takes knowledge, experience, and time to create beautiful and appreciative prints.

yup, i mostly agreed with you said.

yes i know we do have filament stores, but those are usually just small resellers that bought the cheapest filaments from China and mark up the price by 200~300%.

It is sad, you know.

Good that you want to start a community. I too wanted to start a society or club in Malaysia but due to my business occupying most of my time and the lack of participation I decided to KIV this idea.

Anyway, you will need to meet 3D printer users to bring them into the 3D printing community and have better exposure if you want a lively discussion.

Anything you can PM me or just simply discuss with me here.

thumbsup.gif Those are good ideas, I will pm you. but for the time being, getting more people to join the group is the main priority.

Since I need more Silica gel to keep the filament dry, I need to get it in big quantity. Daiso silica gel is expensive if want a lot.

Than to recycle the silica gel, I need to oven it dry at the temperature of 80°c. Advice from the expect seller. This process will be repeat again and again for filament box.

Since I can't use the kitchen oven, microwave or toaster for drying the silica gel (safety food purpose), I decide to modify a toaster.

Toaster is same as oven but cheaper version. But toaster is not temperature precise and can spoil the silica gel when the temperature raise high. I need to control the temperature at around 80°c. Without modify it, it is impossible.

Thing I need.

2nd hand toaster. Found it in 2nd hand shop in good running condition.

A solid state relay to control the heater on/off.

Temperature controller

Thermocouple for sensing inside temperature

Design and print the attachment and wire casing. The wire casing later broken cause by bad design.

Start the modify. Wired up all the component. Place the wire into the heat insulation sleeve. SSR place at behind to dissipate the heat out.

Attach the controller at the side toaster cover. Away from heat. This toaster can be very hot. The PLA material might not survive the heat.

Design again the wire casing.

Fit nicely the casing and controller attachment.

Done. Now I can control the temperature precisely. It take about 30-45min to dry the silica gel. Another usefull is to melt the printing surface to smooth it out. Also can be dry any painting parts.

Total cost is about RM90.

silica gel are food safe... this is why you see them in pills bottle, snacks etc.

Silica gel have 2 type. Food grade and non food grade.

The color wan is non food grade. It been ban in western country.

nope, that was Dimethyl fumarate, not silica gel, silica gel is chemically inert.

Hi guys, may I ask any recommendation for a beginner to get a 3D printer budget below 1k? or anyone to recommend to buy from, or a model name would be good, I'll go search for more info... thanks!!

how is your tinkering skills? below 1k actually, not much options but DIY KITs from taobao , if you are not good at tinkering, i highly suggest that you double up your budget and get pre-assembled machines.
