Optimizing Resin Printing in Colder Temperatures

As 3D printing enthusiasts continue to explore the boundaries of resin printing, adapting to environmental conditions becomes crucial for achieving optimal results. In this article, we will delve into the specifics of resin printing using a unique mixture: a 60/40 blend of Phrozen's  Aqua 8K Gray and Onyx Impact Plus. Our focus will be on adjusting the printing settings for optimal performance in rooms with temperatures below 10 degrees Celsius.

Understanding the Resin Mixture:

    The combination of Phrozen's Aqua 8K Gray and Onyx Impact Plus creates a resin blend that offers a balance of properties, including excellent detail resolution and enhanced impact resistance. However, like any resin, its behaviour can be influenced by environmental factors, particularly temperature.

Challenges in Colder Temperatures:

    Lower room temperatures pose challenges for resin printing. Cold temperatures can impact the flow characteristics and curing reaction rate of the resin, potentially leading to incomplete cures, poor layer adhesion, and compromised print quality.

Setting Adjustments for Printing in Lower Room Temperature:

    To optimize printing with the 60/40 Phrozen's Aqua 8K Gray and Onyx Impact Plus mixture in colder temperatures, with some suggestions from on of the KOC in the Phrozen  Facebook group - Luther, building on his valuable insights and previous experience, here are some key adjustments for optimal printing in lower room temperature:


  1. Increased Exposure Time:
    • Colder temperatures can cause the resin to become more viscous, affecting its flow. Increasing the exposure time provides the resin with more time to settle and ensures proper curing. Experiment with gradually extending exposure times until satisfactory results are achieved.

  2. Elevated Resin Temperature:
    • Warmer resin temperatures can assist in preventing layer separation and improving adhesion. Apply a heat belt to the vat or any other kind of products to heat up the vat to keep resin warm and fluid

  3. Print Speed Adjustments:
    • Slowing down the print speed can provide more time for each layer to cure properly. Giving it a long resting time after the retraction of build plate can also help reduce the failure caused by the bubbles and other issue due to the thickness the resin can turn into in colder temperatures; and slower plate movement can also prevents the model being tear apart due to the higher friction that thicker resin gives to the plate.

Conclusion:

    As you venture into the realm of 3D printing with the 60/40 blend of Phrozen's Aqua 8K Gray and Onyx Impact Plus resin in colder surroundings, skilfully tweaking your printing parameters becomes pivotal for achieving optimal results. Grasping the nuances of how temperature influences resin behaviour and implementing judicious adjustments in your settings empowers you to unleash the complete potential of your resin mixture, even amid challenging conditions. Wishing you a satisfying printing experience!

      How to Create Your Own Resin Profile

      Getting your resin settings right is crucial to achieving a successful print. This is particularly important for those who are aiming for the utmost detail and precision. However, it's often the case that companies only provide resin profiles for their own products—or sometimes they don't provide them at all.      For newcomers to the scene, it can be quite frustrating to spend the majority of their time fine-tuning settings. Moreover, what works perfectly on one printer might not produce the same results on another. This discrepancy arises from the variations inherent to different devices, which shows the necessity to tailor resin settings accordingly.      With that in mind, let's delve into the experience shared by Derek Jackson from J3DTech, also a Phrozen community member. He gives us some insight into the process of refining resin settings. Here's my take on the information: To dial in a resin, there are two ...

      [Mega 8K] Setting Supports on Perforated Build Plate

      Sonic Mega 8K has the largest printing volume of Phrozen's Sonic 3D printer line-up by the time of writing this article. Except the size, perforated build plate that comes with Sonic Mega 8K is also an obvious different from other models in the Sonic line-up.     The reason Sonic Mega 8K comes with a perforated build plate is that, lager the scale the model is, or fuller the build plate, higher the suction force it has to deal with, also longer the time you have to wait for the resin to travel back to its place after retraction. The perforated build plate of Sonic Mega 8K can effectively helps reducing the suction force especially when printing the raft, and also letting resin traveling back to its position after retraction more quickly, preventing model from peeling off from the plate and layer lines happening.     Some people may find it inconvenient working with perforated build plate, as in the slicing software, ther...

      A Simple Tip to Increase the Surface Quality of Prints

       The quality of surfaces of resin 3D  prints varies as it is affected by lots of factors, one of them is the model orientation when preparing the model. Orienting the model, especially for those which has sudden increase or decrease area of cross section, can increase the quality of the model's surface, by minimize the difference between those area of cross sections. This way can also help stabilize the plate-shaped model, spreading out the forces from a single direction to the whole model, decreasing the chance of deformation. ▲ Layer line is a common thing happened on resin 3D prints. This surface annoying many people who pursuit details and perfection. /Evaty Yu     The common way is to orienting the model by 45 degree and see if the result is satisfactory. Sometimes it did work but just doesn't quite there. In this stage most people will simply do the post processing and sand the surface to eliminate those imperfections, but some people would rather adjust and ex...
