Peachy Turns 6 Months Old! πŸ‘

Last time, we've introduced a stray dog named Peachy, which had her fortune to have one of the volunteer Wong, from the local stray rescue and adoption group in Hualian, Taiwan, to made a 3D printed prosthetic for her congenital amputation, who is also a member of Phrozen's Taiwanese group on Facebook.



    After 3 months, Peachy has become 6 months old and has already adopt to the prosthetic Wong has made for her. And she has also become heavier, more stronger then before, which means Wong have to adjust the design of the tailored prosthetic to better fit her current state.

    Wong has also tried out some new material making the prosthetic. Despite other kinds of resin has stronger, more durable result compared to the Phrozen Rock-Black Stiff he's originally used, Rock-Black for its easy to print, high dimensional accuracy, is still the choice for him to do the fast prototyping, and able to resilience to prolonged use, showcasing remarkable resistance to wear and tear.


    

    Here's the translate of the post which Wong updates the project and Peachy recently:

    Hello everyone, I am a volunteer for animal adoption, currently working on creating prosthetics for disabled stray animals. Three months ago, I posted a question about resin selection, and at that time, I received resin samples from the Phrozen company (thanks a million). Now, after some time has passed, I'd like to share my experience.

    The star of this story is a stray dog named PeachyπŸ‘. She usually lives in a dog shelter on the mountain, available for adoption. Occasionally, she comes down the mountain to participate in adoption events. However, due to her natural disability, it's challenging for her to find a home. Therefore, I decided to make a prosthetic for her to improve her mobility. Peach is now 6 months old, approximately 13KG, and has a strong running power (as those who have had dogs would know). Therefore, the material for the prosthetic is crucial.

    While the characteristics of the resin are essential, the printing properties are equally important. I initially tried using ONYX Impact Plus Resin. Although the characteristics of the finished product are excellent and suitable for high-strength applications like prosthetics, the printing process was quite challenging. Especially in thinner areas, deformation occurred, and the surface remained sticky for some time after curing. This made it difficult to immediately test on the dog and, and do the post processing (priming for protections) right away. Moreover, the printing time was significantly long. For volunteers, it's challenging to spend a considerable amount of time on a single part, and it doesn't align with the actual workflow (usually, dogs stay at the event only for a few days, and we can only work on this during evenings and weekends).

    I also tried Phrozen Protowhite Rigid, which is quite hard and can print well in thin or delicate areas. The printing time was relatively shorter. However, even after curing, the surface remained sticky for several days, making it unsuitable for immediate testing on the dog.

    In the end, I returned to Phrozen Rock-Black Stiff Resin. It has sufficient characteristics for prosthetic use, and most importantly, it's easy to print! Cleaning is also easy, and deformation is less likely in large, thin areas. After curing, it doesn't remain sticky.

    Currently, using 3D printing to create prosthetics is not mainstream, but there are many advantages. Especially for stray animal prosthetics, the most important factors are reducing costs and simplifying production. Even if the 3D printing material is not the best, as long as there is a 3D file, a new prosthetic can be printed (in fact, well-made ones are quite durable). Moreover, future printing technology will only improve, and costs will decrease, making animal prosthetics more accessible and benefiting more animals.

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 main factors

[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, there is no indicator

The Principle Behind Fast Resin 3D Printing

TL;DR:  There are several things you should look into when try to shorten your printing time. Before you start to adjust the speed of the setting, find a stable setting as your starting point. Understand your equipment and the material you are using. Choose a resin that requires lower exposing time with low viscosity, and install a releasing film that is not sticky to the cured resin.  Fast printing is a result of the combination of right setting for right tools, experimenting with the setting to optimize it is necessary. Expect to spend time on this process.      Printing fast has becoming a trending topic in Phrozen community recently. After Phrozen released a video promoting their ACF film, with the printer applied with the ACF film ended up prints 6x faster then the other one shown in the demonstration video, people are hyped about this idea.
