As you are opening company in UK, you'll pay UK tax - isn't it?

And which bank account do you get through this service and how can it be opened without visiting the bank?

All this sounds too good to be true.

Start a discourse hosting service. And offer people to make their discussion board for some monthly payment. A lot of people get banned and get de-platformed or simply want a better forum software you can offer them that.
econcon··on Ask HN: Those who left software development for a different technical field?
I never think about what will happen in future, tomorrow I might as well fall under the bus and die. Planning way ahead doesn't help me, I just jump into whatever I find interesting then ride the tide till it's no more.

You can also check on YouTube there is a Canadian I think? Company called ProtoPasta which also makes filament in small shop.

Filament market I think, isn't big enough for the large companies to dominate.

And other thing is logistics, I make locally I can offer cheaper rates to local buyers shipping locally.

econcon··on Ask HN: Those who left software development for a different technical field?
I am a programmer but I prefer physical object business.

During Corona self isolation, I started creating and selling filament:

I documented the journey here: https://medium.com/endless-filament/make-your-filament-at-ho...

The price of filament is still going up.

Since selling filament I am working partime, mostly doing maintenance (updates/patches) existing application.

My friend imports medicines from India. While US often accuses Indian companies of selling shoddy quality drugs, it's interesting they wanted HCQ from India and didn't question its quality.
econcon··on Ask HN: How did/do you promote your side project?
Here's is my side project:

https://medium.com/endless-filament/make-your-filament-at-ho...

I blog about the side project and share it with others who are looking to do similar things.

econcon··on Ask HN: College dropouts whose startups failed, what's your story?
Not a dropout but I moved to partime work and quit living in a big city and moved to semi urban area. Since then I've been working on fun things
econcon··on Ask HN: Side projects that are making money, but you'd not talk about them?
I've no doubt anyone can do this within a few weeks (if they work on weekends only)

People can start with extruding clay or Noddles to start

econcon··on The world might run out of people (2019)
Educated women have more options and they do not marry guys just because they happen to have some comfy jobs and can pay for living expense for her.

A lot of women are adopting "all or nothing" approach, aka "I'd rather live alone than with someone I am not attracted to".

There are various articles where women are interviewed and they report shortage of "attractive males" for relationships. Also others where women claim, "men no longer chase" (my personal opinion is that it's because of metoo men are afraid of pursuing and asking out unless if some woman displays explicit interest)

Meanwhile there are lots of women who have children with the guys they deemed attractive but that guy never commited as a husband or father, some of those are now struggling to pay their bills and raise kids as a single parent. Society has to come forward and help them raise their kids.

Maybe we should get done with traditional marriage and assume every country man or woman is father or mother to every kid existing within the borders of the country and pay for their maintenance and good upbringing as a community as a whole.

Maybe the cost of having kids is too high? And we need to lower it through incentives?

If we choose to not do this - where will the future tax payers come from when the present ones will be on retirement? We borrow from future. Today the taxes you are paying have been used already in past for the welfare of the previous generation. Tomorrow when you'll need welfare, you'll want to have fresh population supporting it.

You can bring in the immigrants but will they have the values which your community needs? Will it require a period of time before they are able to contribute to your society in a positive way?

econcon··on Ask HN: Side projects that are making money, but you'd not talk about them?
We need more research into it I guess also see: https://3dprintingindustry.com/news/greek-researchers-determ...

Here they report improved ABS properties on recycling

>Presumably, you've got to melt and extrude these things somewhere, and heating the plastic to its melting point

Right now I do nothing for emissions.

It happens inside a barrel that reduces a lot of emissions.

The emission will appear near the nozzle and the hopper. As those are the only opening in the barrel.

Once filament exists the nozzle, after 10inches, it goes into a water bath.

In future tho, I'll add HEPA+Activated charcoal filter lid on the hopper and use same for nozzle but with an extraction fan.

>as someone who has 3d printed nearly 100kg with FDM machines in the past year, I can't disagree more

If you run into problems, feel free to reach out to me. My telegram is in the medium article - I'll help you solve all your problem while extruding filament.

>even only looking at 'cheap' PLA, let alone PETG.

I don't extrude PLA or PETG at all, buying these special resins is difficult and costs 3x or 5x the ABS. I ask for the lowest wrappage and viscosity blend specially made for extrusion.

I buy general purpose polymers like extrusion grade granules of TPU, Nylon12 (it absorbs the least moisture in all nylons) and ABS - buy them from reputable companies they come in membrane sealed bags of 25kg. These polymers are mass produced and finding them for cheap around $1.4-$3 is easy.

>Filament widths are wildly inconsistent even within the same companies products -- this leads to extruder jams on the cold side.

Before jumping into making filament I researched on Amazon and found most filament being sold is within plus minus 0.05 to 0.02mm tolerance. Upon further research I found that these tolerances are trivial to achieve with sufficiently powered extruder and the industrial machines used for making medical grade silicone tubes can achieve plus minus 0.001mm tolerance using dual axis laser and feedback loop controlling pulling speed at high frequency.

You extrude fast, you lose tolerance. Companies might want more througput if their customers don't care about the dimensions and only want ultra cheap stuff.

I don't splice, all my filament is continuous length.

>I've received dusty spools that were vacuum packed, and spools that were vacuum packed with condensation visible on the inside of the packaging (humidity and moisture can damage many filaments, leading to lengthy rebake procedures if the filament survives at all.).

You need to seal the filament spool right after it's ready with a 10-20grams of dessicant. There are special vaccume seal bags and handheld vaccum sealer for low volumes like I am doing it's good enough.

>but the quality of your product must come from efforts you don't realize, because the quality on the market for cheap filament is

You'll have to troubleshoot the issues with your filament yes but once you've figured it out - it becomes easy.

I've written several part articles on my medium blog with many more to come where I'll write about common issues and their solutions.

I have had more difficulty in shooting down bugs in production code than building extruder. Just saying that skill level of a programmer and some random guy off the street might have difference. With some guidance anyone can do it.

My wife is now tuning extruder, filling the hopper and extruding filament as good as me. She doesn't have technical education background. Arguably, I find baking to more difficult than extruding filament, but it could be just that baking doesn't exite me.

I appreciate you concerns but quality of filament has lots of parameters but most common problems appear when:

1. Seller has bought the filament like PLA in bulk from china for $3-4 a spool. They buy a full container load at once to make it as cheap as possible. After a year on shelf even when placed in vaccum sealed bags, PLA becomes brittle. And you'll have very hard time printing with it - it will snap at different places randomly and your prints will fail.

2. Inconsistent diameter - these are extruding too fast or using low quality resin with no good operator on machine available for tuning. For example if I want to extrude 1kg filament and I add 200gram resin of A company, I ran out then I add 200gram resin or B company, you'll have to tune extruder again. Better create filament in large batches from the resin from same batch.

econcon··on Ask HN: Side projects that are making money, but you'd not talk about them?
I make 15-20 rolls a day. I'll be adding few more extruders soon - waiting for shipping of additional parts to start building new machines on weekend.

Well, picking up beach plastic is too much work - I am not that involved, I need easy automated work haha.

There are already companies who pick and sort, shred and wash plastic for you and even convert it into granules - so it's much better to give them more business so the are able to pick more of the waste.

econcon··on Ask HN: Side projects that are making money, but you'd not talk about them?
In this virus season alone I've made $8000 in sales.

You'll find various subreddits where people are buying around 5-10spools a month. Imagine how much virgin plastic is being added like that to the environment.

I've been creating filament and selling it:

https://medium.com/endless-filament/make-your-filament-at-ho...

This activity also help recycle waste plastic.

Production cost of filament is $7.5 per 5kg and filament roll has 850 gram filament and can be sold for $20-30 per spool

It's trivial to get the quality right.

You can sell rolls on Amazon, eBay and Etsy or your own Shopify store and use Facebook ads/Google Ads to advertise your website.

That said I didn't use any ads to sell filament! Only few days ago I started Shopify store and paid $5-10 in Facebook ads. Since we accept credit card, it's not too much of a risk for buyer to buy it from us (even when are new)

I work from home so I take 5 minute break and walk to my garage and check if the filament machine successfully is running on auto pilot

Thing is filament doesn't have huge demand, neither it has very less demand. So you can dominate local demand by creating quality filament.

I focus on fulfilling local demand, I've gained customers who need large supply of filament of ABS, TPU and Nylon12.

If people do actually come to compete with me, it's a win win. More plastic recycled = less plastic entering landfill.

econcon··on Ask HN: I recently lost my job, I want to pursue blogging as a career. Thoughts?
It's hard to make money blogging. I suggest becoming a YouTuber instead, consuming YouTube content is lot easier.

And if you want to make money, I suggest you try e-commerce.

econcon··on Ask HN: What can I build for you?
Alibaba clone, most small countries don't have anything like alibaba. Yea I know it's a global but mostly Chinese owned platform.

I'd personally like such B2B platform to be more available to people like Discourse the forum software is.

econcon··on Ask HN: Just left college, unsure of what to do
Hello! Sometime back I was in similar position so i started working partime from home. I take the boring and high paying work which most other refuse to accept.

Meanwhile, I find validation and fullfilment through hobbies like metal fabrication/machining and creating electronics/mechanical projects. I've workshop full of tools like mills, lathe, laser/plasma cutter, 3d printers and several website where I use my tools to deliver the item designed by my customer their door - it's lot of fun!

Recently, so am I always looking for ways to expand my workshop and make money on side.

Lately I've been creating filament from waste plastic

https://medium.com/endless-filament/make-your-filament-at-ho...

Here's what research has to say about it: https://3dprintingindustry.com/news/greek-researchers-determ...

Often what you like doing doesn't pay well or isn't very dependable. So I suggest trying to convert your hobbies into side businesses and see if they can prove to be worthwhile while still taking partime jobs in the skill that pays well but you don't like.

econcon··on Australian researchers set record for carbon dioxide capture
India is building freight corridors which will be using electricity except for a couple of remote links on hilly areas.

This will bring economics of scale right. When all emision will be in couple of power stations, it can be scrubbed and treated better and cheaper than going after individual diesel engines of trucks and locomotives.

Freight corridors and land ports are going to lower the greenhouse and fog generation drastically.

econcon··on Optical Baking: CO2 Laser Browning of Dough [pdf]
I looked into buying CO2 laser and built one own my own.

It doesn't need much, just couple of aluminium extrusions for frame and V wheel for motion and couple of Nema17 motors. Also cooling for tube and optics.

But laser tube life is crap, I am still waiting for cheap laser systems to come to market but it seems there is nothing cheaper than CO2 available in 60-100w range.

econcon··on Ask HN: When is it time to give up on a side project SaaS?
Without seeing your product it's very hard to give any advise.

Maybe you've not done marketing correct, maybe your product has steep learning curve. Maybe too many alternatives exist at lower price point.

There are lots of maybes, so send me an email I'll take a look zerocorebeta@gmail.com and offer some feedback.
