Innovation Horizons: Metal 3D Printing, Space Manufacturing, and AI’s Impact

As of August 24, 2025, the global innovation landscape is rapidly evolving, driven by groundbreaking advancements that are reshaping industries and redefining our capabilities. This newsletter explores three pivotal areas: the accelerating evolution of metal 3D printing, the revolutionary potential of in-space manufacturing, and the strategic imperative of navigating future innovation frontiers in areas like AI-driven finance.

Pushing the Boundaries: Latest Advances in Metal 3D Printing

Metal additive manufacturing is advancing rapidly, with breakthroughs enhancing material properties, process efficiency, and sustainability. Caltech’s Hydrogel-Infusion Additive Manufacturing (HIAM) now supports dual-metal printing, demonstrated with copper–nickel alloys, yielding materials with significantly increased strength and tailored properties Source. Meanwhile, Saarland University researchers found that applying sound during powder bed fusion (PBF) improves component quality by compacting metal powder, leading to reduced porosity, smoother surfaces, and stronger parts with just 3-5 watts of sound power Source.

Industry leaders are scaling up for real-world applications. MX3D secured €7 million to deploy its M1 Metal AM System and Print-on-Demand services globally, producing large-scale parts with over 80% less material waste for sectors like energy and aerospace Source. Eplus3D has delivered over 100 „super-meter“ metal Laser Powder Bed Fusion (LPBF) 3D printers, highlighting a trend towards greater adoption of multi-laser systems Source. Sustainability is also a key focus; Bright Laser Technologies (BLT) integrates ESG principles with fully automated production lines, closed-loop powder circulation, and gas recovery, claiming up to 80% CO₂ emissions reduction Source. These advancements underscore a dynamic period, with the metal 3D printing market projected to reach $60 billion by 2034 Source Source.

Building the Future in Orbit: The Rise of Space Manufacturing

The field of In-Space Servicing, Assembly, and Manufacturing (ISAM) is revolutionizing space exploration by shifting manufacturing capabilities into orbit, reducing reliance on Earth-based supply chains. ISAM encompasses in-space servicing (repair, refueling, upgrading satellites), in-space assembly (constructing large structures like telescopes in orbit), and in-space manufacturing (ISM), which involves on-demand fabrication of parts and tools using techniques like 3D printing in space Source. NASA is actively pursuing these capabilities, with 3D printing experiments already proven feasible on the International Space Station Source.

Crucial to this vision is In-Situ Resource Utilization (ISRU), or „living off the land,“ which involves extracting and processing resources from celestial bodies. For instance, lunar regolith offers oxygen and metals, while polar water ice can be converted into rocket propellant Source. The convergence of ISAM and ISRU promises a new era of sustainable, accelerated, and autonomous deep-space exploration, redefining humanity’s presence in the cosmos Source.

Navigating the Future Frontiers of Innovation

The global business landscape is continuously reshaped by emergent technologies and strategic innovation. Artificial Intelligence (AI) is transforming the investment sector by revolutionizing portfolio modeling, data governance, cloud infrastructure, and cybersecurity. Firms are focused on leveraging AI for enhanced decision-making while addressing data quality and navigating regulatory frameworks like the Digital Operational Resilience Act (DORA), highlighting a need for robust internal capabilities Source.

Nationally, initiatives like the U.S. National Science Foundation’s Directorate for Technology, Innovation and Partnerships (NSF TIP) are accelerating transformative technologies. NSF TIP fosters regional innovation, translates research into market applications, and develops a skilled workforce, supporting thousands of startups and small businesses in critical technology R&D to strengthen American competitiveness Source. As these innovation frontiers expand, continuous learning and strategic adaptation will be essential for organizations aiming to lead.

The collective advancements in metal 3D printing, the bold ventures into space manufacturing, and the pervasive integration of AI in critical sectors underscore a period of profound technological transformation. These innovations not only promise enhanced efficiency and sustainability across terrestrial industries but also open unprecedented pathways for humanity’s expansion beyond Earth. Staying informed and strategically adapting to these rapidly evolving frontiers will be key to unlocking future growth and maintaining a competitive edge in a global economy shaped by relentless innovation.

Automating Twitch Notifications with n8n Webhooks

Automating Twitch Notifications with n8n Webhooks

Have you ever wanted to automatically trigger actions whenever you go live on Twitch? With n8n and Twitch EventSub, you can capture Twitch webhooks and connect them to Twitter, Discord, or any other service. In this guide, I’ll show you how to set up a webhook from Twitch to n8n and use it to automate your workflow.

Prerequisites

  • A Twitch Developer account
  • An n8n instance with a valid HTTPS domain (e.g. https://n8n.hellbz.de)
  • Basic knowledge of webhooks

Create a Twitch App

Go to the Twitch Developer Console, register your application, and note down the Client ID and Client Secret.

Create an n8n Webhook

In n8n, create a new workflow with a Webhook Trigger node. Set it to POST and copy the Production URL as your Twitch callback.

Subscribe to Twitch EventSub

POST https://api.twitch.tv/helix/eventsub/subscriptions
Authorization: Bearer <YOUR_APP_TOKEN>
Client-Id: <YOUR_CLIENT_ID>
Content-Type: application/json

{
  "type": "stream.online",
  "version": "1",
  "condition": { "broadcaster_user_id": "<YOUR_TWITCH_USER_ID>" },
  "transport": {
    "method": "webhook",
    "callback": "https://n8n.hellbz.de/webhook/twitch",
    "secret": "<YOUR_SECRET>"
  }
}

Handle the Verification Challenge

Twitch sends a challenge string on subscription. You must respond with that string to verify the webhook. In n8n, add a Respond to Webhook node with:

{{$json["challenge"]}}

Verify Twitch Signatures (Recommended)

For security, validate Twitch’s HMAC signatures by computing sha256 = HMAC(secret, message_id + message_timestamp + raw_body).

// Verify Twitch EventSub HMAC signatures
const crypto = require('crypto');

// Read Twitch headers
const sigHeader = $json.headers['twitch-eventsub-message-signature'];
const msgId     = $json.headers['twitch-eventsub-message-id'];
const timestamp = $json.headers['twitch-eventsub-message-timestamp'];

// Raw body (if Webhook node has "Raw Body" enabled)
const raw = Buffer.from($binary.data.data, 'base64');

// Compute HMAC
const secret = $vars.twitchSecret; // store your secret securely
const hmac = crypto.createHmac('sha256', secret)
                   .update(msgId + timestamp)
                   .update(raw)
                   .digest('hex');

const expected = `sha256=${hmac}`;
if (sigHeader !== expected) {
  throw new Error('Invalid Twitch signature');
}

return [{ json: { verified: true, event: $json.body } }];

Connect to Twitter (or Other Actions)

  • Twitter: Post an “I’m live now!” tweet.
  • Discord: Send a message to your server.
  • Email: Notify your subscribers.

Add the desired node in n8n and map fields (e.g., stream title + link).

Final Workflow Outline

  1. Webhook Trigger (receives Twitch events)
  2. Respond to Webhook (echo challenge)
  3. Code (validate HMAC)
  4. Action (Twitter/Discord/etc.)
