Filament question

Noob here, getting ready to buy my first printer. I will be making exclusively functional items for use in my shop and garden. I know that PLA will not be a good choice -need better strength, heat tolerance and UV resistance. My question is, will PETG be suficient for my purposes, or will I need ABS or ASA? If PETG will work I would get the A1 printer, but if I need ABS/ASA IT looks like I would need the P1S -big price difference! Could I use the A1 for ABS?

It’s not recommended. You will have problems with warping, adhesion and splitting.

If you can afford the P1S then thats is what I would suggest as it gives you the option of printing most filaments.

Whether PETG is enough depends on the functional items you intend to print. Unless you live in an extreme environment, PETG will stand against ambient (e.g. sun) and UV resistance and entail excellent mechanical properties. ASA exceeds PETG in heat and UV resistance but comes at a higher cost and can be said to be more demanding to print.

I use both in my garden and beach accessories without an issue, but the choice depends on the use.

The A1 seems a superb printer but is utterly different from the P1S. As Jon stated, the P1S is the one to choose for functional prints.

Should probably be in Filament, not MakerWorld. You’ll get more input from people :slight_smile:

About to buy my first printer. Will be printing exclusively functional items for my workshop and garden. Strength, UV resistance and heat tolerance will be important. Will PETG be sufficient for my purposes, or will I need ABS/ASA, which will require a more expensive printer (A1 vs P1S)?

The PETG-HF seems to have a rather low Tg, so you’ll probably want to use a 3rd party PETG or go straight for ABS/ASA.

As someone who also uses my printer for mostly functional mechanical parts that I design myself, if you’re considering an A1, I can promise you that the limitations of not being able to use a wider range of ‘functional’ filaments will ultimately lead you to buyer’s regret. It’s just not worth cutting corners.

For example, here’s something that can’t be done as well with PETG or ASA but is perfect with PC which the A1 can’t handle. For machined parts where I want to add threads, I used to use PETG with heated threaded brass inserts. However, I found that Polycarbonate(PC) to be really suitable for tapping threads directly into the material itself. Often, especially with thin walls at the boundary of a model, direct threads are stronger simply because you can cut them in a smaller space than threaded inserts require. I will never say that it will produce the “prettiest” prints. It does require some post processing to clean up the edges but for strength and high temp capabilities, outside of CF and more expensive and exotic materials, it is within budget and perform incredibly well for parts fabrication.

Refer to Bambu’s filament guide for a good comparison tool.

If you’re looking for mostly outdoor use, here’s what a quick Internet shows

Filament Type UV Resistance Notes
ASA Excellent Highly resistant to UV; designed for outdoor use and remains stable over time.
PETG Moderate Some resistance, but can degrade over time with prolonged UV exposure.
ABS Low Poor UV resistance; becomes brittle and yellows with long-term UV exposure.
PC (Polycarbonate) Moderate to Good Better UV resistance than ABS but can yellow over time with high UV exposure.

If you also want to avail yourself of CF filaments for certain projects, the A1 just can’t handle the nozzle temps.

Sorry, but Zammer3D suggested that I post the question in the filament section, so I did.

I moved your original thread for you (I think that sends a notification?) after you posted and now have merged your second thread in to this one to maintain the responses.
