Kiln 1.1.9 makes the everyday loop smoother and more self-sufficient. Kiln now keeps itself up to date (your agent offers to install the new version and does it with your go-ahead), no longer wrongly prompts you to set up an outside AI service before it makes an object, and shows you a preview every single time it makes something. Free accounts can now sign in to the web app and land somewhere useful, accepting the Terms of Use is a one-time tap that sticks everywhere you use Kiln, and your saved decorations follow you to every device. On the Business and Enterprise tiers, any design can become a clean dimensioned drawing a machine shop can use, and the chemical-resistance answers now cover far more of the filaments real parts are actually made of.
Kiln keeps itself up to date
When a newer version of Kiln is out, your AI assistant now offers to install it for you (“want me to update Kiln for you now?”) and does it with your go-ahead, instead of leaving you to copy a command. It holds off while a print is running, and tells you plainly that one quick restart finishes the job. Free for everyone.
Design objects without an API key
A few item-creation paths used to wrongly prompt you to set up an outside AI service before you could start. Now Kiln defaults to designing the model itself and previews it for you to refine, and a reference photo works the same keyless way. You describe what you want, Kiln makes it and shows it to you, and you go from there. Free for everyone.
A preview every time you make something
Kiln already popped up a preview the moment you created or changed a model, but a few paths quietly skipped it, so you would have to ask “show me.” Those blind spots are fixed: the preview just appears, every time, whether you described the design in plain words, split it into colors, or changed it mid-print. Free for everyone.
Free accounts get a real home on the web
A free Kiln account now signs in to kiln3d.com and lands on a home that helps you connect Kiln to your AI app, so you can start designing and printing right away. The cloud workshop (version history, branches, and sharing for your designs) stays a Kiln Pro feature, but signing in and getting started is free.
Accept the Terms once, everywhere
Accepting Kiln’s Terms of Use is now a one-time tap, remembered everywhere you use Kiln: the command line, your AI assistant, and the web app. You are never asked twice.
Your decorations follow you (Kiln Pro)
Kiln got better at rendering a saved decoration (a logo, photo, or pattern) onto a model in a single step, free for everyone. Upgrade to Pro tier or higher and a decoration you save once comes back ready to use on any device you sign into, the full design and not just a thumbnail, so your branding travels with you instead of living on one machine.
Common items go straight to the right maker (Kiln Pro)
Ask for something Kiln already supports, a coaster, tray, keychain and more, and it now reaches for that tuned generator automatically instead of building from scratch. You get a cleaner result faster, without having to know which tool to ask for.
Turn any design into a production drawing (Business)
Kiln can now give you a clean, dimensioned drawing of a part: top, front, and side views with real measurements, plus PDF and DXF files (the formats a machine shop or client works from). For something you designed in Kiln it fills in the exact measurements for you; for a model you imported, it measures what it can and says so plainly.
Chemical answers for more of the filaments you actually use (Business and Enterprise)
Kiln’s “will this part survive that liquid?” check now covers far more of the materials functional parts are made of: flexible, polycarbonate, polypropylene, and carbon-fiber grades. The safety warnings stay free for everyone: if it is a bad idea, Kiln still says so. The go-ahead verdicts are paid: everyday exposures (cleaners, oils, sunlight, weather) are Kiln Business, and the answers someone could get hurt by (fuels, automotive fluids, food contact) are Enterprise.
Smaller fixes that add up
A few more: starting a brand-new design in the workshop and saving its first version no longer errors, so a fresh design saves cleanly the first time (Kiln Pro). Locking a design version as official and provably yours no longer gets stuck after sign-in, it just uses your signed-in account. And the in-app Terms link now always points to the current published Terms.
