Von Perry Crowdfunding for 3D Printing Homes in Texas
Dallas-based startup Von Perry wants to build 3D-printed homes across Texas, but it needs funding to do so, so it’s launching a $2 million fundraising campaign on the platform. StartEngine crowdfunding. The startup is expected to complete the first 3D-printed proof-of-concept for its AM home building technology next month, and is already planning six more custom projects with its geopolymer concrete material and hardware from Total Kustom. With this funding, Von Perry will hire two new construction teams, fuel ongoing research and partnerships with three Texas universities, and launch its proprietary Arcus software platform, which uses AI to modify custom home designs. and consolidate the construction process. Despite interest from other parts of the world, Von Perry doubles down on Texas, which has codes and regulations that make building easier.
“We’re actually building real houses using 3D printers, and it’s a jaw-dropping moment for [people]. Because they don’t even believe it’s possible,” said Sebin Joseph, co-founder and CTO of Von Perry. “But it is a reality that is happening and is slowly revolutionizing the sector. We need more investment, more talent in this area to make [it] grow and be mainstream. It will certainly become mainstream in the next 30 years.

Evonik is Stratasys’ latest hardware partner
Stratasys has announced that specialty chemicals company Evonik is the third hardware partner for its P3-based Origin One 3D printer, which offers excellent precision and surface finish, along with a diverse and growing line of high-performance materials. Evonik will offer its expertise to help Stratasys develop and manufacture ready-to-use, industrial-grade photopolymer materials to improve the P3, and the first – P3 Deflect 120 – is available for customer order in the US and some European countries. The Stratasys-validated material has been tested by Evonik for reliability on the Origin One, and results suggest a 10% strength improvement over a competing DLP system. Additionally, the high temperature P3 Deflect 120 can be used to print parts with a heat deflection temperature of up to 120°C, making it a good choice for manufacturing applications, such as molds .
“Feedback from our customers indicated that there was a real market need for a high temperature resistant photopolymer in our portfolio. In summary: this new partnership with Stratasys means that we can offer more applications to Stratasys customers to develop 3D printing in manufacturing,” said Alex Sant’Anna, Director, Additive Manufacturing and Hardware Solutions – Americas, Evonik.
Exaddon appoints AXT as distributor in Australia
Swiss metal additive microfabrication (µAM) technology manufacturer Exaddon has appointed AXT as the official distributor in Australia for its CERES µAM system. This printer uses spot electroplating to deposit metals, such as copper, gold, nickel, silver, and platinum, in complex geometries onto conductive substrates in the range of 1 to 1000 µm with lower resolution to the micrometer. CERES has a proven track record in areas such as microelectronics and neural interfaces, an emerging field that connects computers to the human nervous system with 3D printed needles or pillars, and can print materials with superior strength and durability. to those that multi-step lithography microfabrication is capable of achieving, and post-processing methods like etching are not required. In addition, the system can operate in a standard laboratory.
“As a Swiss company, we strive to provide exceptional technology combined with excellent customer support based on expertise and experience. For us, it was an obvious choice to appoint AXT as our distributor in Australia; they have an intimate knowledge of their local market and, above all, an excellent reputation for adopting cutting-edge technology such as ours,” said Exaddon CEO Edgar Hepp. “We are confident that AXT will represent the unique technology we provide at Swiss quality level.”
YouTuber 3D prints prototype Shockwave jet engine
YouTuber Integza, also known as Joel Gomes, makes cool science and tech project videos that teach people about science concepts in an entertaining way. In one of his latest projects, he used resin 3D printing to build his own detonation-powered pulse jet engine, otherwise known as a shockwave jet engine. Pulsejet engines are lightweight, valveless engines that inject fuel through a pipe, before being ignited in a series of pulses. They only require a few moving parts, if any, so these engines are easy to build and maintain, but not very efficient, so Integza decided to 3D print a prototype valveless engine capable of continuous detonations. These engines inject oxygen and propellants into long cylinders open at one end and closed at the other, and the contents of the pipes are ignited, causing the fuel to burn and rapidly transition to an explosion. The pressure from this shock wave then pushes the exhaust out of the pipe outlet to create thrust.
Pulsejet engines have complex geometries, but do not allow continuous thrust, so Integza thought it could generate more power with this type of engine using detonations. He used a Prusa SL1S 3D printer and Siraya Tech resin to create a combustion chamber connected to a long acrylic pipe and oxygen and fuel intake valves, and ignited it with a high voltage generator , which he ran with an Arduino controller. But, he didn’t know if it actually created detonations, so he then injected pure oxygen into the chamber, which allowed him to reach a rate of 80 meters per second. Based on this resin prototype, the YouTuber machined a second version from metal, which he claims can create “clean, consistent bangs”, while hitting up to ten pulses per second. He has made the 3D model design files for his prototype available for free download via Onshape if you want to try one out yourself, and you can watch his video below:
Only-Games.co launches full color 3D printing for tabletop models
Finally, Only-Games.co was launched in 2021, as part of established manufacturer 3DC, to facilitate the manufacture and distribution of digital game assets for the countless tabletop game players who lack access to a 3D printer. Just a few months ago it was acquired by MyMiniFactory and has flourished as hundreds of independent designers have chosen the platform to 3D print over 100,000 tabletop models for customers around the world. The Only-Games.co software automatically charges a manufacturing fee, depending on the complexity of the design, and the creator decides to design their own packaging, before setting a retail price; minus this manufacturing cost, these independent designers keep 90% of the models’ final income. Today, the company announced the launch of on-demand color 3D printing and distribution of these creations, with a delivery time of less than five days. Not only is this great news for the company’s growing network of designers and tabletop gamers, it also helps MyMiniFactory continue to build its MetaReverse universe, trained to use 3D printing to reconnect digital users in the physical world.
“We can provide this service because we have built the right process, machinery, software, packaging and most importantly the right team to provide the global community of miniature and model designers with access to the best capabilities of manufacturing in their category. And, above all else, we make sure to provide a fair business model for creators,” said Alex Ziff, Founder of Only-Games.co and Co-CEO of MyMiniFactory.
