Catable 3D Printer Resin Review

That the world is full of creativity is beyond doubt that is to say, there is no limit to imagination. And therefore there is need for more platforms, more liberty and choice, more conceivable ways to explore ones creativeness and display the impressive awesomeness. That is why technology keeps on advancing. Such an example is the printing technology.

In an effort to tear down barriers, and give people the freedom to express their thoughts by printing whatever they wanted and designed, 3D printing technology was borne and since then high resolution 3D printers have been developed, giving people the opportunity to fabricate whatever they conceived.

3D printing technology is on its early days but the high-resolution stereo lithography (SLA) 3D printing technology is promising to eclipse the conservative Fused Deposition Modeling (FDM) 3D printer.

How do the resin printers work?

Stereo lithography (SLA) 3D printing makes use of liquid materials called photopolymers. The photopolymers solidify when they are exposed to light. This photopolymerization process is what drives the DLP/SLA printing.

In resin printers photopolymerization is achieved either by use of a laser or a digital projector. The SLA printer utilizes this laser technology and the digital light processing printer (DLP) utilizes the projector technology whereby a digital projector is used to project the entire slice of the object

Why the photolithography 3D printers?

As aforementioned, there are many types of 3D printers, each with different shapes and sizes. There is the

  • Fused Deposition Modeling (FDM) like the Makerbots and Ultimakers that print by use of heat, the heat is applied through a nozzle to a filament.
  • The powder bed 3D print techniques, here a laser or glue is used to fuse the powder particles together

But the photolithography printing technology is the best amongst them all. Photolithography has been utilized to make the best resin (DLP/SLA) 3D printer and to make them appeal to many consumers, they have been made affordable, reliable and easy to use. The models are now selling for as less as $ 5000.

Product features

When light falls on the resin it becomes solid, and where light does not shine, the liquid remains. Photolithography method makes accurate prints because of the remarkably small feature size of 100 nm.

  • Updated castable: this ensures fine detail print as there is no ash remains after burning. The castable resin also captures crisp to ensure that the detail is precise enough and the surface is left as smooth as possible. This makes it instrumental in jewelry designing as it produces an accurate 3D design model
  • High resolution with incredible detail to produce large prints faster
  • Connected printing: this is smart printing as it keeps you informed
  • Ease of use
  • Compatibility: can work with a wide range of materials
  • High resolution
  • Compact
  • Open platform
  • Affordable

What are the advantages of the castable resin?

Castable resin gives one the potential to print in accurate detail, with a material created precisely for direct investment casting. As aforementioned, the castable resin is clean as it has been tested and found to leave no residues and ash remains on the surface. The waxlike appearance of the resin makes it easy to scrutinize and prepare printed parts. The material achieves:

  • Fine details: with ultimate precision one is able to create inscriptions, delicate filigree and migraine. Organic shapes and designs can be created with excellent detail. The features like filigree and prongs print accurately to one’s objective and cast neatly requiring fewer cleanups
  • Smoother surface finish: this ensures minimal touch-ups prior to casting and also minimal metal loss due to precise layer placement. In addition, the finishing time is reduced. With less finishing one can achieve a stunning mirror polish.
  • Accuracy: all fine features are brought out. From spikes to holes in jewelry pieces, this is ideal for stone-setting
  • Opacity: it has a waxlike appearance which gives it the opaque surface. This makes it easy to scrutinize and inspect the details of the print. The resulting color mapping will indicate all the differences and reveal dimensional accuracy
  • Clean exhaustion: the burnout curve has been extensively verified to give beautiful results. According to Formlabs, a pioneer in 3D Printing technology, the castable resin has been completely enhanced for excellent burnout performance, but one is free to develop a specific burnout and casting process that they desire. This is made possible by the supply of guidelines that are provided for consumers to follow.
  • Super speed: a DLP printer using a 180 watt lamp will take 2 seconds to cure a 0.05 mm layer, this is an incredible curing speed.

Open source platform makes it possible to use different variety of resins with diverse properties; it can also work with standard vacuum investment casting requirements. The resin is biocompatible that is, it is certified for medical and dental use. The resin has worked for bronze, tin, copper and even iron.

It is easy to use the resins as it comes with all pigments already mixed in. all it requires is one to make the initial calibration and follow this finishing instruction.

  1. To remove excess resin, use a vat of Isopropyl Alcohol (IPA), it requires 2 minutes of agitation and a soft brush
  2. Excess IPA should be eliminated using compressed air or a cold blow-dryer
  3. Place under the sun or use a UV lamp to cure

To get the targeted durability, prints made out of castable resins are to be post-cured for approximately 2 hours at a temperature of 45 degrees Celsius and with a lighting source of 405nm wavelengths

Advantages of 3D printers that utilize the SLA or DLP technology

Improved speed and resolution: the SLA Technology is of great quality, no details are left out in the prints. Printe5rs such as the kudo3D Titan 1 allow larger and faster printing bringing one’s creation to life.

Great adaptability and open source: the software that accompanies the printers is highly configurable and with the ability to adapt to any model and different resin varieties

The resin container is durable: it is of superior quality to facilitate hours and hours of printing. Approximately 500 hours a container

Less print failure rate: no breakdowns, one needs only fewer supports

Drawbacks

The cost of materials is high, which makes them expensive, also there is a limited range of material one can use on the SLA printer

The resin is expensive too
