I could only afford the 100 gram spool because the full spool is $60. $60 for PLA and the mixing process. I will try to save to get a full spool-have you made enough money to gift me one? You could write it off probably. I was able to print half of a chess set, so I have some high density stainless steel filled HTPLA chess pieces but not an entire set. Will you ever make the full spool affordable for 16 year olds with no money and drug addict parents? If there was ever a candidate for a free spool please let it be me. I am so lonely.
This was my favorite filament out of all of them. I could only get the 100 grams because I dont have any money, but I was able to print 3/4's of a raspberry pi case! so that is great
This filament was really cool; I could only afford the 100grams because the full spool is 60$ for PLA. Maybe if I keep buying your products you will eventually reward me for my loyalty?
This brand is really cool, I wish the spools werent 60$ because I am poor but try to build things. One day maybe they can sell the PLA filaments for cheaper, until then I will plan out dream builds and cry.
Very impressed with this filament! Keep innovating!
This Material Performed so well! I was concerned when the customer requested it, and after a little research I found a great profile some created and made few tweaks and the project turned out perfect!! So much i bought more to continue using it for other projects! Thanks Protopasta for producing such a Unique Filament
Imperfect?? I dig this color!!, I vote for "Burning Barney" for the name. I know most of PP offerings are intended to be bright and glittery but I would enjoy a rustic collection showcasing some deeper tones like this, Keep up the great work and I appreciate the chance to acquire the "mistakes".
Far exceeded my expectations. Found the closest to Nissan Skyline's Midnight Purple line.
This is gorgeous stuff -- I used it as the backing for a silhouette bookmark and it turned out stunning! Prints cleaning and no issues with stringing or clogs.
This is my first experience with Protopasta's PLA filaments and I have to say that it's simply amazing stuff. I have a Bambu A1, using a 0.2 nozzle, and the detail I've achieved with this filament has been nothing short of brilliant. It prints like a finest-quality PLA, but has the heat resistance of PETG. What more can you want??
Fluorescent Blue is both blue and fluoresces. Just what grandma asked for.
Every time i get a grest product from yhis company! Fun colors and quality products!
I only made some small Mastermind pegs with it, but it's very captivating to look at.
I love what Protopasta does. For context, I print every day, from functional items to support a production line for my day job, to demonstration models I use to teach design at a local community college a few times a week, 3d printing is a regular part of my problem-solving workflow. Protopasta feels like a brand having as much fun making the filament as I do using it. Their unique and interesting selection brings me back to the experimental mad scientist feeling I had when I started out in 3d printing a decade ago and I love that feeling of trying something new. Thank you for not being afraid to play with new things on the extruder line, and keep up the great work!
Great product! Finally, a reliable laser-etchable material. It is not uncommon to be able to mark some 3d printable materials but knowing what will mark and how it will look in the end is a matter of tedious trial and error. This is the first filament I am aware of meant/sold just for this purpose. I hope they expand their line with more colors and materials but this a great starting point.
I am using an xTool F2, which is a galvo, and using the 5W IR to get these results. I have yet to experiment with a diode on this material.
For basic engraving: I am using 100% power and 1700mm/s, and 100 lines per cm. Use 2 passes to darken it up a little, but 1 pass still looks good,
For the image engraving, I am using 130 dot duration, 40% power, 500 dpi, and 1 pass
I am going to share this to the xTool material settings library so hopefully this will be selectable for everyone soon.
I ran many tests before settling on these recommendations; however, I am not an expert in this field, so please do your own testing before marking something important to you. The hope is this should at least get you started.
Thank you Protopasta!
