Polycarbonate 1.75mm 3D Printer Filament
- rigid.ink’s Polycarbonate filament is an engineering grade, extremely impact-resistant thermoplastic. Perfect for a wide range of uses where you need one of the toughest plastics around, that can handle higher temperatures for demanding applications.
- With a Glass Transition of around 150°C your prints will hold their dimensional accuracy for temperatures up to around 120-130°C, but please be aware you need a hot end nozzle temperature of at least 280°C+. If you need a print to withstand higher temperatures, Polycarbonate could be it.
- If you’ve ever had a long print fail in the last 30 minutes, you’ll know how frustrating and disappointing it can be. More often than not, the cause is inconsistent filament ruining your prints. That’s why we pride ourselves in using pure raw resins without contaminants to potentially block your nozzle, or weaken your end use parts.
- Variances in the advertised diameter of your filament can lead to slightly thicker or thinner layers, which not only reduce finish quality but also integrate random weak faults in your prints that are prone to fractures. That’s why we extrude to industry leading tight tolerances, for perfect print layers, every single time. We guarantee 100% printing reliability.
- It’s not just our unmatched filament quality that’s well renowned either. If you ever get an issue with your rigid.ink (unlikely) our efficient, friendly and knowledgeable technical support team are always on hand to get you back on track. We we’re not satisfied with your prints, until you’re ecstatic with them.
Polycarbonate Filament 1.75mm
Are you looking for a material that will give your printed objects truly impressive tensile strength and impact resistance, but is also easy to work with and gives outstanding results?
If so, then rigid.ink polycarbonate printing filament is the thermoplastic material for you.
rigid.ink polycarbonate, also known as PC, is a remarkably strong thermoplastic that is also lightweight and amazingly transparent. It is marketed under the trade name Lexan and has a wide variety of commercial uses. Everything from CDs and DVDs to bullet proof glass to riot gear to electronic display screens and computer or phone cases are made of polycarbonate.
Polycarbonate finds such a wide variety of uses because of its high impact strength - far greater than glass and about ten times that of an acrylic like PMMA. However, that strength comes with a relatively light weight. PC has less than half of the density of glass, but has a comparable transparency. In fact, polycarbonate actually transmits visible light better than many types of glass.
It is this relatively light weight and transparency, combined with incredible strength, which makes rigid.ink polycarbonate such an attractive 3d printing material. That high impact resistance means that rigid.ink PC filament can stand up to the strain of excessively demanding applications.
It can also resist relatively high amounts of heat, but can be bent at room temperature without cracking of breaking. Compare those properties to other transparent thermoplastics, like PMMA, which have a lower impact and heat resistance and will crack and break if bent.
The properties of rigid.ink polycarbonate filament make it an excellent choice for prototyping, especially in situations where transparency and non-conductivity are required. It is far from delicate and will not deform under high energy conditions. Yet, at the same time, its transparency means that it is able to transmit light with startling clarity. This means that it is able to produce strikingly gorgeous printed objects when used correctly.
A quick glance at the data stats for rigid.ink polycarbonate will confirm its impressive strength and relative light weight. rigid.ink polycarbonate has a specific gravity of 1.18 g/cm³. This makes it comparable in density to PMMA and PLA and about one fifth denser than ABS. It has a Rockwell hardness of R 121, making it harder than PMMA, ABS and PLA. Yet, it’s in the category of overall strength that polycarbonate sets itself apart from other thermoplastics.
It has a maximum tensile strength of 11,200 psi which is comparable to PMMA (12,100 psi).
However, it has a tensile break strength between 75% and 150%. Compare this to the tensile break strength of PMMA (1.8% - 7.2%), PLA (1% - 12%) and ABS (4.6% to 27%). This means that while both polycarbonate and PMMA are strong and hard, rigid.ink polycarbonate has an ability to withstand torsional stress that far exceeds any other thermoplastic.
When you print with rigid.ink polycarbonate filament, you get a strong and tough material that can handle weight and successfully survive stress events. You also get a material that has a tensile strength that allows it to flex in situations that would break, deform or shatter other thermoplastics.
So when you need a strong, tough and flexible material that is also capable of producing amazingly delicate and beautiful objects, look no further than rigid.ink polycarbonate. You do need to print at high temperatures though, so do check if your printer can reach the correct temperatures.

Wow, just.... wow.
Firstly it arrived the day after I ordered it, and shipping was only £3. Thanks rigid.ink!
Secondly, this stuff is crazy strong! I printed a normal sized benchy torture test on my original Prusa i3 MK2S (which it handled like a champ btw), and it took all my strength to snap the roof away from the body. It also looked amazing, being really translucent. My nozzle was at 295C and my bed at 120C, and I used an enclosure with an ambient temperature of 38-40C and humidity at 10-15%.
I had some difficulty with warping, but it was readily resolved with some blue masking tape, glue stick and a shorter distance between the nozzle and the bed for the first layer. Many thanks to metacollin on the forums for providing solid settings. Go check it out:
I rarely write reviews, but the quality of the service and filaments warrants an exception. I purchased a number of different filaments (that's why you might see this review in a few places) and followed the material settings as given. I was really impressed by the outcome of each one I tried. Printed fist time and superbly! At this stage I cannot recommend this company and filaments highly enough. I should add that I used 300 degrees as the nozzle setting so can't speak for lower temperatures.
Would be better if this was formulated to require a slightly lower extruder temperature - Sailfish only goes up to 280 even with an all-metal hot-end! Print speed lowered to compensate. Looks great and very strong! Would like to see a black version if possible?
I cannot, for the life of me, get this to print on my brand new Prusa MK2S. Any ideas??
Easy to print with straight out of the box.
If using a Creator Pro (max temp 280 degrees, important to use all metal hot end, PTFE is not good at these temperatures), set the bed a bit higher than recommended and print a bit slower (1800mm/min base speed).
Bed adhesion is critical, you'll get crazy warping if it's not stuck down properly, however, if it is stuck down properly it's really stable.
I used an extra large separation distance from the raft of 0.3mm and double layer separation distance from supports.
On the whole this material should be no problem to anybody with a reasonable amount of 3D printing experience and the prints come out very rigid and strong.
