  • Esun Pure PolyCarbonate Filament from 3D Printer Store

    Poly-Carbonate commonly referred to as just PC, is one of the most capable Functional Polymers in the world. PC is the King of cost-effective engineering thermoplastics thanks to High Temperature resistance, UV stability & Flame Retarding. Flame retardant level: UL94:V2 Pure PC handles a whooping 140C continuous operating temperature - only to be beaten by PEI / PEEK Print temperature range: 240-280℃; Black PolyCarbonate Esun Filament 0.5Kg in 1.75mm ABS will only handle 85C in most continuous high temperature applications. You can boil water in pure PC but you can't in ABS or any blended PC-ABS. Pure PC is thus food safe & common in food containers.

  • FlashForge Hunter DLP Resin 3D Printer - Now in NZ DLP 3d printers offer better accuray, precision & sharpness over other common cheaper LCD based 3d printers. This is because DLP printers project entire images much like a movie projector does across a screen, whereas LCD screens have a signifcant amount of light bleed in each pixel which causes exposure bleed & inherent rounding. DLP systems can provide consistent high power necessary across the surface area, in comparison to LCD printers. The FlashForge Hunter now brings the power of DLP resin technology at a very Affordable price. The easy to use free software has pre-calibrated profiles for standard material making it extremely easy to use for industry professionals who want a printer that prints, rather than a machine where they spend time experimenting to gain their perfect results. The machine also supports third party materials, so you can print any resin presently available if you want to trial it out.
  • Phrozen makes the best Entry Level, Easy to Use, & Extremely Versatile Dental 3D Printers in the market out of all the brands we have assessed. If you want to enter Digital Dentistry on a low budget, but still want to have pre-calibrated profiles for common materials & applications, then the new 2022 Phrozen Sonic platform is your best choice. The Sonic 4K XL is the bigger version of the standard sonic 4k, & allows printing a larger number of full archs on the bed simultaneously, for faster speeds. The larger size makes it ideal for thermoforming moulds, aligners, retainers, & many other dental applications where larger size helps. While LCD powered 3d printers may not be the fastest or the best when compared to our professional DLP based dental 3d system like the Desktop Health's EnvisionTec 3D Printers, what these Phrozen's do have is a very low price point of entry that still doesn't require experimentation like you otherwise would with cheaper non-dental resin 3d pritners on the market. These printers support a huge range of materials out of the box, pre-validated for popular Keystone, NextDent, & many other popular dental resins. The Phrozen Sonic 4K also comes in a larger XL which we sell, & is perfect for orthodontics, to be able to print more of the larger models like Full Archs in 1 go.

  • Why Ultrasonic cleaners when Wash & Cure units seem to be so easy to use? Ultrasonic vibrations loosen out debris from any surface surface efficiently & quickly using harmless forces. The frequency of motion they form safely dislodges uncured resin particles at a microscopic level that other devices cant create. Ultrasonic cleaners can clean most resin parts in 3 mins. Most entry level washers can't beat that. The fact that there is no heavy movement, allows debris to settle rather than float around. This makes it far easier to get the parts clean with less fluid use. Resin cleaning liquids like Monocure Resin away & Phrozen now make it a cheaper & safer option than to use IPA or other explosive alcohol based cleaners. When cleaning castable resins or industrial resins in particular, ultrasonic cleaners will give you the edge.
  • Polyether Ketone Ketone (PEKK) is a semi-crystaline thermoplastic in the Polyaryletherketone family. It has higher heat resistance than PEEK, offers exceptional chemical resistance, & can withstand high mechanical stress.

  • So we have fast resin 3d printers now, but have you thought about post processing faster? Take away the mess & hassle of cleaning resin 3d prints by hand. And dont wait nearly 50 mins to be able to use your 3d prints with conventional wash & cure devices. With our Ultrasonic 40KHz industrial style washer & a Heated UV Curer, you will speed up your post processing time down to just 15 mins. Thats just 15 mins from when your print is out to when a usable part is in your hand. Standard curers do not heat the chamber. Heating not only speeds up the cure, but more importantly, it significantly improves the internal structural integrity of your part. Normal washer devices tend to rely only on the standard dissolution rate of resin into the cleaner. Whereas ultrasonic cleaners actively separate the resin stuck to the part with a 40KHz wave, thus speeding up the cleaning process dramatically. Wash for just 5 mins with resin cleaning liquid in the ultrasonic & then cure for 10 mins in the heated curer - you have your self a factory quality usable 3d printed part!

  • Big Parts, High Accuracy, & Reliability - In ALL Filament Materials currently available. The Creatbot D600 Pro is based on the successful D600 commercial grade FDM 3D printer. It features Servo Controlled motors & closed loop feedback electronics, giving it the most precise head calibration of any similar sized large scale 3D Printer on the market. It has become common to see low cost large size 3d printers on the market. So why would you buy this one? Just doubling the size of every single part & giving you a large bed, doesn't lead to a successful print. With cheaper printers you will see them advertise a size like 500x500mm, but when you actually try to print a part that size, your builds will consistently fail. Multi-day prints will be composed of layer shifts in the XY direction, even a 0.1mm XY shift will land your part in the rubbish bin. This is why real commercial grade 3d printers are designed to be able to produce what the spec sheet actually has on it. And that is the reliability you need, so that you dont come back to a 3 day print only to throw it in the bin. Large 600mm x 600mm x 600mm actively convection heated build volume makes it possible to print large parts one piece with ease. And the servo control system doesn't cause stepper drivers to overheat, which is all too common in kit style large 3d printers.
